"Well done, good and faithful servant. You have been faithful over a little; I will set you over much. Enter into the joy of your master." — Matthew 25:21
✠ INTRODUCTION — WHY THE CHURCH CANONISES SAINTS
Every human life ends at death. For most people, even the most beloved, the memory fades within a generation or two — the face forgotten, the name unspoken, the story dissolved into the silence of history. The Church does something different. She takes certain human lives — lives that ended in obscurity or in martyrdom, in monasteries or in palaces, in the first century or the twenty-first — and she declares, with the full authority of the Vicar of Christ, that these specific people are in Heaven, that they can be invoked with confidence, and that their example is proposed to the whole world as a model of Christian life.
This declaration is called canonization — from the Latin canon, meaning rule or list: the person is placed on the Church's official list of saints, enrolled in the canon of the holy, proposed to the universal Church for veneration and imitation. And the process by which the Church arrives at this declaration — the long, careful, rigorous, prayerful investigation that precedes it — is one of the most remarkable juridical and theological procedures in the history of any institution on earth.
The process exists for three reasons that the tradition has always articulated together:
First, to protect the faithful from false holiness. Not every person whose cause is opened will be canonized. The investigation is designed to be genuinely searching — to distinguish authentic heroic virtue from reputation, public piety from private integrity, the apparent holiness of the charismatic leader from the genuine holiness of the person whose interior life is in order with God. The process is the Church's guarantee that those she proposes for imitation and invocation are genuinely worthy of both.
Second, to honour those who have truly served God. The saints have given everything — in many cases, including their lives — in the service of the God who made them and the Church that formed them. Canonization is the Church's act of gratitude, her public and permanent recognition that this life mattered, that this sacrifice was not wasted, that this person will never be forgotten as long as the Church endures.
Third, to strengthen the faith of the living. The saints are the Church's most powerful apologetic — the argument for the truth of the Catholic faith that no theological treatise can replicate. When the Church proposes a ThΓ©rΓ¨se of Lisieux or a John Paul II, a Josephine Bakhita or a Kateri Tekakwitha, she is saying: look at what this faith produces. Look at what grace does in a human life. Look at what a human being can become when they give themselves completely to God. The canon of saints is the Church's gallery of the possible — the evidence that the promises of the Gospel are not merely theological propositions but lived realities in the lives of specific, historical, particular human beings.
✠ A BRIEF HISTORY OF HOW THE PROCESS DEVELOPED
The canonization process as it exists today was not invented whole cloth — it developed over seventeen centuries, becoming progressively more systematic and more rigorous as the Church's experience of the possibilities of error and of fraud accumulated.
✦ The Age of Popular Acclamation
In the earliest centuries of the Church, the recognition of saints was essentially a popular act. The martyrs were the first and most obvious saints — those who had died for the faith, whose deaths had been witnessed, whose graves were known, whose anniversaries were celebrated. Their recognition required no formal procedure: the community that had seen them die simply continued to venerate them, to pray at their tombs, to invoke their intercession. The bishop confirmed and regulated what the people had already decided.
The transition from martyrs to confessors — to saints who had not died for the faith but had lived lives of exceptional holiness — produced the first complications. How does one verify holiness that was not attested by the supreme sacrifice? The answer, in the early centuries, was still essentially local and episcopal: the bishop of the diocese where the holy person had lived investigated the claim, interviewed witnesses, visited the tomb, and — if satisfied — permitted public veneration. The most famous example of this early episcopal canonization is St. Martin of Tours, whose holiness was attested by his biographer Sulpicius Severus and whose cult spread rapidly across Gaul and beyond in the late fourth century.
✦ The Papal Reservation — The Decisive Turn
The turning point in the history of canonization is the pontificate of Pope Alexander III (1159–1181), who issued the decisive decretal Audivimus (c. 1170–1171), asserting that no one should be venerated as a saint without the authority of the Roman Church. This decretal — later incorporated into the Liber Extra of Gregory IX (1234) — effectively reserved the right of canonization to the papacy and ended the era of purely local and episcopal saint-making.
The reasons were partly theological — the universal Church's interest in the universal validity of its saints — and partly practical: the scandals of the preceding centuries, in which persons of dubious holiness had been locally canonised for political reasons or popular enthusiasm, had demonstrated that episcopal oversight alone was insufficient. The papacy stepped in not to diminish episcopal authority but to guarantee the integrity of a process on which the faith and the devotion of the whole Church depended.
✦ The Great Systematisers — Sixtus V, Urban VIII, and Benedict XIV
Three pontificates transformed the canonization process from a relatively informal papal procedure into the sophisticated legal and theological machinery that the modern world inherited:
Pope Sixtus V (1588) established the Congregation of Rites — the Vatican office charged with overseeing the causes of saints — giving the process its permanent institutional home and its procedural framework for the first time.
Pope Urban VIII (1625 and 1634) issued two crucial decrees that tightened the process significantly. The decree of 1634 established the requirement that fifty years must elapse after a candidate's death before their cause could be opened — a rule designed to ensure that popular enthusiasm had time to be tested against the longer scrutiny of history. Urban VIII also definitively established the role of the Promotor Fidei — the Promoter of the Faith, known popularly as the Devil's Advocate (Advocatus Diaboli) — whose function was to argue systematically against every claim made on behalf of the candidate, raising every possible objection, identifying every weakness in the evidence, and ensuring that the cause survived the most rigorous possible challenge before advancing. The Devil's Advocate was not a cynic or a sceptic — he was the Church's guarantee that enthusiasm had not overwhelmed rigour.
Pope Benedict XIV (1740–1758) — before his elevation as one of the greatest canonists in the history of the papacy — wrote the definitive treatise on the subject: De Servorum Dei Beatificatione et Beatorum Canonizatione (On the Beatification of the Servants of God and the Canonization of the Blessed). This monumental work — the product of decades of scholarly engagement with the canonization process — codified the Church's theology and jurisprudence of sanctity with a precision and a comprehensiveness that shaped every subsequent development. It remains, to this day, the foundational reference work for anyone who wishes to understand the process at its deepest level.
✦ The Modern Reform — John Paul II and Divinus Perfectionis Magister
The most significant reform of the modern era came on 25 January 1983, when Pope St. John Paul II issued the Apostolic Constitution Divinus Perfectionis Magister — promulgated on the same day as the new Code of Canon Law — which fundamentally restructured the canonization process for the contemporary Church.
The principal changes were:
The Congregation of Rites was reorganised as the Congregation for the Causes of Saints (now the Dicastery for the Causes of Saints under the reorganisation of the Roman Curia by Pope Francis in 2022).
The Devil's Advocate was abolished — or rather, his function was dispersed into the process itself, with the requirement of rigorous examination built into the structure rather than concentrated in a single adversarial office. This change was controversial: critics argued that removing the Devil's Advocate weakened the process, and the dramatic acceleration of canonizations under John Paul II himself (482 saints — more than all his predecessors combined) fed that concern.
The diocesan phase was substantially strengthened — more of the investigative work was returned to the local Church, with Rome's role becoming primarily that of review and confirmation rather than original investigation.
The fifty-year waiting period after death was replaced with a requirement that the bishop wait five years before opening a cause — though the Pope retained the power to waive even this requirement (as he did for Mother Teresa, whose cause was opened by John Paul II just two years after her death in 1997, and for John Paul II himself, whose cause was opened by Benedict XVI just weeks after his death in 2005).
The path from the death of a holy person to their inscription in the canon of the saints passes through four formal stages, each with its own title, its own procedures, and its own theological significance.
✠ STAGE ONE — SERVANT OF GOD
The Opening of the Cause
"Every scribe who has been trained for the kingdom of heaven is like a master of a house, who brings out of his treasure what is new and what is old." — Matthew 13:52
✦ The Recognition of Holiness
Every cause begins not with a formal legal procedure but with a human reality: a community of people who knew someone and cannot forget them. The priest who brought Communion to the dying for forty years and was known by everyone in the parish as a man of God. The laywoman who ran the soup kitchen and whose prayer life was a source of wonder to everyone who witnessed it. The bishop who governed his diocese with justice and gentleness and died in the odour of sanctity. The young martyr whose death for the faith has never been forgotten.
The first movement is always organic, always from the ground up — the fama sanctitatis, the reputation for holiness, that persists among the people who knew the candidate and spreads to those who did not. The Church does not manufacture saints by bureaucratic decision. She recognises those whom God has already made — and the evidence of that making is the fama: the persistent, widespread, spontaneous conviction of the faithful that this person is with God and can be approached with confidence.
✦ The Postulator
When the fama is sufficiently established — typically through the sponsorship of a religious congregation, a diocese, or a national bishops' conference — a Postulator is appointed. The Postulator is the professional advocate for the cause: trained in canon law and in the history and theology of the canonization process, responsible for assembling the evidence, guiding the investigations, liaising between the local Church and Rome, and representing the cause before the competent Church authorities at every stage of its progress.
The Postulator is not a propagandist. They are not tasked with making the strongest possible case regardless of the evidence. They are tasked with assembling the truth about the candidate and presenting it honestly — and if the truth reveals that the candidate does not meet the Church's standards, the Postulator has an obligation to say so and to advise that the cause not proceed.
✦ The Bishop's Role and the Opening of the Inquiry
The cause is formally opened by the bishop of the diocese where the candidate died — or, in some cases, where they principally exercised their ministry. The bishop issues the nihil obstat — the declaration that there is no obstacle to proceeding — after consulting with the Congregation for the Causes of Saints in Rome, which checks that no prior judgement has been made about the candidate's cause and that the cause does not raise issues that would make it inadvisable to proceed.
With the nihil obstat granted, the bishop formally constitutes a diocesan tribunal: a panel of investigators, theologians, historians, and canon lawyers who will conduct the investigation at the local level. The candidate is given their first formal title:
Servant of God.
This title does not confer any liturgical veneration — the Servant of God is not yet proposed to the faithful for public veneration, no feast day is assigned, no public prayer to them is yet authorised. It simply acknowledges that the Church has begun to look seriously at this person's life, that the question of their sanctity is now formally before the Church, and that the process of discernment has commenced.
✦ The Diocesan Investigation
The diocesan tribunal conducts a comprehensive investigation into every available dimension of the candidate's life:
The writings — every text the candidate produced: letters, diaries, sermons, books, articles, notes, prayer books. These are examined by theological censors for doctrinal orthodoxy. A single statement contrary to defined Catholic doctrine is sufficient to halt the cause. The Church does not propose to the faithful as a model of holiness anyone whose written teaching is doctrinally suspect.
The testimonies — witnesses who knew the candidate personally are summoned before the tribunal and examined under oath. Their testimonies are recorded verbatim and form the evidentiary core of the diocesan investigation. The witnesses are questioned not only about the candidate's good qualities but about any weaknesses, failures, inconsistencies, or faults — the tribunal is not looking for a hagiography but for the truth.
The virtues — the central question of the diocesan investigation is whether the candidate exercised the Christian virtues to a heroic degree. This is a precise canonical standard, not a vague aspiration. The virtues in question are the three theological virtues (faith, hope, and charity) and the four cardinal virtues (prudence, justice, fortitude, and temperance), together with the virtues proper to the candidate's particular state in life. Heroic means exercised with exceptional consistency, exceptional intensity, and exceptional fidelity — not perfect (the saints were not sinless) but genuinely extraordinary in the degree to which the virtue characterised the person's life.
The non cultus — the investigation also confirms that no public cult has developed around the candidate in violation of Urban VIII's decrees. The faithful may venerate the candidate privately, but no public liturgical veneration — no feast day celebrated publicly, no public veneration of images, no official invocation in public prayer — is permitted until beatification. This rule protects the process from being pre-empted by popular enthusiasm.
The Acts of the Diocesan Investigation — the complete record of the investigation, bound and sealed — are then forwarded to Rome, to the Dicastery for the Causes of Saints.
✠ STAGE TWO — VENERABLE
The Declaration of Heroic Virtue
"You are the light of the world. A city set on a hill cannot be hidden." — Matthew 5:14
✦ The Roman Phase — The Relator and the Positio
When the Acts of the diocesan investigation arrive in Rome, a Relator — a scholar of the Dicastery, typically a historian or theologian — is assigned to the cause. The Relator's task is to take the raw material of the diocesan investigation and transform it into the Positio super virtutibus — the formal document that will be placed before the theologians and cardinals who will decide whether the candidate's virtues were truly heroic.
The Positio is one of the most demanding scholarly documents in the Church's juridical tradition. It must present the life of the candidate in full historical context, assess every piece of evidence with critical rigour, answer every objection that has been raised, and make the theological case that the candidate exercised the virtues to a heroic degree. A Positio for a major cause may run to thousands of pages and take years to prepare.
✦ The Congregation of Theologians
The completed Positio is submitted to a panel of theologians who examine it with critical independence. Their task is not to find reasons to approve or to reject — it is to assess honestly, in the light of Catholic theology and of the evidence presented, whether the case for heroic virtue has been made. If the majority of the theologians are in favour, the cause proceeds to the cardinals and bishops of the Dicastery. If the majority are against, it does not.
✦ The Declaration of Heroic Virtue
When the cardinals and bishops of the Dicastery have given their approval, the cause is presented to the Pope, who — if satisfied — issues a decree recognising that the candidate exercised the virtues to a heroic degree. The candidate is given their second formal title:
Venerable.
The title of Venerable is a significant moment in the cause — the first formal papal act in the process, the first declaration by the Vicar of Christ that this person's life bears the marks of genuine heroic sanctity. The Venerable is not yet beatified — they cannot yet be publicly venerated liturgically, no feast day is assigned, no public prayer is yet authorised — but the Church has said, with papal authority, that this person lived a heroic Christian life.
The declaration of heroic virtue is the watershed of the cause. Before it, the cause is primarily an historical investigation. After it, it is primarily a theological and miraculous one.
✠ STAGE THREE — BLESSED
Beatification — The First Permission to Venerate
"I am the resurrection and the life. Whoever believes in me, though he die, yet shall he live." — John 11:25
✦ The Requirement of a Miracle — and Why
For candidates who did not die as martyrs, the Church requires the verification of at least one miracle attributed to the candidate's intercession after their death before beatification. This requirement is the most misunderstood aspect of the entire process — and the one that most requires careful theological explanation.
Why does the Church require a miracle? Not primarily as a test of the candidate's power but as a sign from God. The logic is precise and has been consistent since Benedict XIV articulated it with his usual clarity: the Church is a human institution, and human institutions make mistakes. The investigation of the candidate's virtue is conducted by human beings, using human evidence, subject to human limitations. A miracle — a genuine, medically inexplicable, instantaneous cure or other supernatural event that occurs in response to prayer directed to the candidate — is understood as God's own confirmation of the Church's verdict. It is God saying, through the language of the miraculous, yes, this person is with me, their intercession is heard, you may safely propose them for veneration.
This is why the miracle must occur after the candidate's death — to demonstrate that the intercession is being exercised from Heaven — and why it must be specifically attributed to the candidate's intercession, not to a general prayer or to the intercession of another saint.
✦ The Investigation of Miracles — Medical and Theological
The investigation of an alleged miracle is one of the most rigorous procedures in the Church's entire juridical life. It involves two phases: the medical and the theological.
The Medical Investigation is conducted, in the first instance, at the diocesan level — the same tribunal that investigated the candidate's virtues takes the testimony of the person who experienced the alleged miracle, of the doctors who treated them, and of any witnesses. All available medical records — including X-rays, laboratory results, surgical notes, and specialist assessments — are gathered and examined. The diocese forwards its findings to Rome.
In Rome, the alleged miracle is examined by the Consulta Medica — the Medical Consultants of the Dicastery for the Causes of Saints, a panel of medical specialists (typically including practitioners of the relevant specialty) who are appointed for their professional expertise and who examine the case without knowledge of the candidate's identity. The Consulta Medica does not pronounce on the miraculous nature of the event — it pronounces only on the medical question: is there a natural medical explanation for what occurred? If the medical panel unanimously concludes that the cure is medically inexplicable — instantaneous, complete, lasting, and without medical intervention capable of producing it — the finding is forwarded to the theologians.
The Theological Investigation then examines whether the medically inexplicable event can be attributed to divine intervention through the candidate's intercession. The theological panel assesses the prayer that was offered, the specific attribution of the request to the candidate's intercession, the relationship between the prayer and the event, and whether the event is consistent with the Church's understanding of miraculous divine action.
Only when both panels — the medical and the theological — have given their positive assessment, and the cardinals and bishops of the Dicastery have approved, is the alleged miracle presented to the Pope for his approval.
✦ The Special Case of Martyrs
For candidates who died as martyrs — who were killed specifically because of their Catholic faith, in hatred of that faith (in odium fidei) — the Church waives the requirement of a miracle for beatification. The logic is both theological and practical: the martyr's death is itself the supreme attestation of faith, the act of charity so complete that it encompasses the giving of one's life. The Church has always held that martyrdom is a direct path to Heaven — that the martyr passes immediately from death to the presence of God, without the need for Purgatory's purification, because the blood shed in martyrdom has the effect of a second Baptism. If this theological conviction is sound, no further miraculous confirmation is needed: the martyrdom itself is the sign.
The investigation of martyrdom is, however, equally rigorous — and in some ways more complex. The tribunal must establish that the death occurred, that it was caused by human agents, that those agents were motivated by hatred of the Catholic faith specifically, and that the martyr accepted death freely rather than fleeing, without having provoked the persecution by imprudent behaviour. The last condition has generated significant theological debate in cases involving, for example, martyrs who actively sought martyrdom rather than passively accepting it — a debate that the tradition has generally resolved in the martyr's favour when the other conditions are clearly met.
✦ Notable Modern Examples of Miracle Investigation
The causes of the twentieth and twenty-first centuries have produced some of the most carefully documented and most medically dramatic miracle investigations in the history of the process:
Blessed Margaret of Castello — whose beatification miracle involved a cure attributed to her intercession that had been investigated by the Medical Consulta, ruled medically inexplicable, and confirmed as miraculous by the theological panel.
St. John Paul II — whose canonization miracle was the cure of a French woman, Sister Marie Simon-Pierre, from Parkinson's disease — the same disease from which John Paul II had himself suffered. The cure was medically documented, rapid, and complete. The Medical Consulta could find no natural explanation. The theological panel confirmed attribution to John Paul II's intercession. He was canonized on 27 April 2014.
St. Teresa of Calcutta (Mother Teresa) — whose beatification miracle involved the cure of a Bengali woman, Monica Besra, from an abdominal tumour in 1998. The medical investigation confirmed that the cure was inexplicable by natural causes. She was beatified by John Paul II on 19 October 2003 and canonized by Pope Francis on 4 September 2016 — nineteen years after her death, an extraordinarily swift process by historical standards.
✦ The Beatification Ceremony
When the miracle has been approved and all the conditions met, the Pope — or, since John Paul II delegated this authority, a cardinal acting in the Pope's name — celebrates the Beatification Ceremony, typically in the candidate's home diocese or country. The ceremony includes the formal proclamation:
"We declare that the Venerable Servant of God [Name] may henceforth be called Blessed, and that a feast in their honour may be celebrated... in the places and in the manner established by the norms of law."
The candidate is given their third formal title:
Blessed.
The title of Blessed — Beatus or Beata — is the Church's first formal permission for public liturgical veneration. The Blessed receives a feast day, an Office and Mass in their honour, and the authorisation for public prayer and veneration — but this veneration is local rather than universal: it is permitted in the Blessed's home diocese, their religious congregation, or their country, but it is not mandated for the universal Church. The universal Church will enter only at canonization.
✠ STAGE FOUR — SAINT
Canonization — The Infallible Declaration
"Come, you who are blessed by my Father, inherit the kingdom prepared for you from the foundation of the world." — Matthew 25:34
✦ The Second Miracle
For canonization, the Church requires the verification of a second miracle attributed to the candidate's intercession — this time occurring after beatification. The timing is significant: the miracle must occur after the candidate has been officially declared Blessed, which means that the person seeking the cure was praying specifically to the Blessed, invoking their newly confirmed intercessory power. The second miracle is subject to exactly the same rigorous investigation as the first: diocesan inquiry, Medical Consulta, theological panel, cardinals and bishops of the Dicastery, and finally papal approval.
The requirement of two miracles — one for beatification, one for canonization — reflects the Church's characteristic double confirmation: in ore duorum vel trium testium stat omne verbum — by the testimony of two or three witnesses every word is established (Matthew 18:16). The divine confirmation of the candidate's heavenly status is given twice, at two different stages of the process, separated in time and independent in their occurrence.
As with beatification, martyrs are exempt from the miracle requirement for canonization. The Church has always held that the blood of martyrdom suffices.
✦ Equipollent Canonization — The Ancient Exception
Before proceeding to the canonization ceremony, it is important to note a parallel path that has existed for certain ancient saints: equipollent canonization (canonizatio aequipollens) — the recognition of saints whose cults are ancient, whose veneration has been immemorial, and for whom the full formal process would be historically impossible because the witnesses are long dead and the documents long lost.
Equipollent canonization requires three conditions: an ancient and immemorial cult, the consistent testimony of serious historians to the candidate's virtues, and the continuation of the cult among the faithful. It does not require miracles — because the antiquity of the cult is itself understood as the historical accumulation of miraculous testimony over centuries. Pope Francis used this path to canonize several saints in recent years, including St. Hildegard of Bingen (2012, technically under Benedict XVI) and St. Gregory of Narek (2015).
✦ The Canonization Ceremony
The canonization ceremony is celebrated by the Pope himself — always, in every case, without exception. This is because canonization is understood in Catholic theology as an infallible act of the papal magisterium: the Pope, speaking as the supreme teacher of the universal Church, solemnly and definitively declares that the candidate is in Heaven and may be venerated by the whole Church. This is one of only a handful of acts in which the Pope's infallibility — defined by the First Vatican Council in 1870 — is directly exercised.
The ceremony typically takes place in St. Peter's Square in Rome, before a congregation of tens of thousands — pilgrims from the new saint's home country, members of their religious congregation, representatives of the universal Church. It includes the formal proclamation:
"For the honour of the Blessed Trinity, the exaltation of the Catholic faith and the increase of the Christian life, with the authority of our Lord Jesus Christ, and of the Holy Apostles Peter and Paul, and Our Own, after due deliberation and frequent prayer for divine assistance, and having sought the counsel of many of our brother bishops, we declare and define [Name] to be a Saint, and we enrol him/her in the Catalogue of the Saints, and we establish that throughout the universal Church he/she is to be devoutly honoured among the Saints. In the name of the Father, and of the Son, and of the Holy Spirit. Amen."
The ringing of the bells, the release of white birds, the unfurling of the new saint's image on the facade of St. Peter's — these are not liturgical ceremonies but human expressions of a joy that the liturgy itself, even at its most solemn, can barely contain.
The candidate receives their final and permanent title:
Saint.
The Saint receives a feast day in the universal Roman Calendar — or, more commonly in the modern era, a feast day that may be celebrated universally but is not included in the General Calendar unless the saint's significance is judged to be of universal importance. They receive a proper Mass and Office. Their relics may be publicly venerated. Their intercession may be invoked by the whole Church. Their image may be displayed in every church in the world.
✠ THE EXTRAORDINARY SIGNS — BEYOND MIRACULOUS CURES
While the verified miracle — typically a medically inexplicable healing — is the canonical standard for progress in the cause, the Church has always recognised a range of extraordinary phenomena associated with genuine sanctity. These are not required for canonization, but they are noted, investigated, and received by the tradition as additional testimonies to the candidate's holiness.
✦ Incorruptibility
The incorrupt preservation of a saint's body — the failure of natural decomposition to occur, despite the absence of embalming or other preservative treatment — has been attested in the history of Catholic sanctity with a frequency and a documentary detail that places it beyond reasonable historical doubt.
The bodies of St. Bernadette Soubirous of Lourdes were exhumed three times — in 1909, 1919, and 1925 — and found each time to be substantially preserved, the skin waxen and pale but intact, the features still recognisable. She now lies in a glass reliquary in the Chapel of St. Gildard in Nevers, France, where she can be seen by any visitor — her face covered with a wax mask to protect the original features, but the body beneath substantially incorrupt after more than a century.
St. John XXIII, exhumed in 2001 for the formal recognition of his relics in preparation for his beatification, was found to be remarkably preserved despite burial for thirty-seven years without embalming — his features still recognisable, his vestments still intact. He now lies in a crystal reliquary in St. Peter's Basilica, where pilgrims may venerate him.
The Church does not require incorruptibility for canonization and does not automatically interpret it as a miraculous sign — it is noted and documented but not entered formally into the miracle process. The theological tradition has generally understood incorruptibility as a divine confirmation of the body's dignity as the temple of the Holy Spirit and as a sign pointing toward the resurrection of the body that every Christian awaits.
✦ The Odour of Sanctity
The odor suavitatis — the sweet fragrance, often described as the scent of roses, flowers, or incense, that is sometimes perceived at the death of a saint or at the opening of their tomb — has been attested in the lives of hundreds of saints across the tradition.
At the death of St. John Bosco in 1888, witnesses reported a powerful fragrance that filled the room and persisted for hours. At the opening of the tomb of St. ThΓ©rΓ¨se of Lisieux in 1910, a fragrance of roses was widely reported — a detail that has since become one of the most consistent testimonies associated with her intercession, fulfilling her promise to "let fall a shower of roses" after her death.
The fragrance is understood theologically as a sign of the soul's beauty — the interior beauty of a life conformed to God radiating, in these extraordinary cases, into the physical order, as the soul's perfection leaves its mark even on the body it has departed.
✦ The Liquefaction of Blood
The most famous example — and the most regularly occurring — is the liquefaction of the dried blood of St. Januarius (San Gennaro), Bishop of Benevento and martyr (†305), kept in two sealed glass ampoules in the Cathedral of Naples. On the feast of St. Januarius (19 September) and on two other occasions each year, the dried, solid blood — dark brown and compact — has been observed to liquefy, turning liquid and bright red. The phenomenon has been recorded consistently since the fourteenth century, has been examined by scientists without natural explanation, and has been the occasion for profound popular devotion in Naples for seven hundred years.
When the liquefaction fails to occur — which it does rarely but occasionally — the tradition in Naples has always interpreted it as a warning of disaster, and the historical record offers several cases where the non-occurrence preceded earthquakes, famines, or political upheaval.
✦ Bilocation
Several saints in the tradition are attested to have appeared simultaneously in two different places — most famously St. Pio of Pietrelcina (Padre Pio, 1887–1968), whose reported bilocations were so numerous and so extensively witnessed that they form one of the most thoroughly documented cases of this phenomenon in the history of the Church. The Congregation for the Causes of Saints examined the bilocation testimonies in Padre Pio's cause with great care; they were not entered as formal miracles but formed part of the broader testimony to his extraordinary holiness.
✦ The Stigmata
The bearing of the wounds of Christ in the body — the stigmata, the subject of a separate page on this blog — is among the most dramatic and most theologically rich of all the extraordinary phenomena associated with Catholic sanctity. From St. Francis of Assisi (who received the stigmata in 1224 on Mount La Verna and is the first historically attested stigmatist) through St. Catherine of Siena (whose stigmata were invisible during her lifetime at her own request), through Blessed Anne Catherine Emmerich, through Padre Pio (whose visible stigmata lasted for fifty years, from 1918 to 1968), the tradition has accumulated a testimony to this phenomenon that is among the most remarkable in the history of religion.
The stigmata are not required for sainthood and do not by themselves constitute the miraculous evidence required for canonization. But they have consistently accompanied the causes of those who bore them, adding to the cumulative testimony of extraordinary holiness that the investigation assembles.
✠ THE PACE OF CANONIZATION — FAST AND SLOW
One of the questions most frequently asked about the canonization process is: how long does it take? The honest answer is: anywhere from a few years to several centuries.
The shortest causes in modern history are those where the evidence of holiness was so overwhelming, the documentation so complete, and the causes so pastorally urgent that the normal timelines were accelerated:
St. Teresa of Calcutta — canonized nineteen years after her death (1997–2016). John Paul II waived the five-year waiting period to open her cause in 1999.
Pope St. John Paul II — canonized nine years after his death (2005–2014), with Benedict XVI opening his cause within weeks of his death.
St. ThΓ©rΓ¨se of Lisieux — canonized twenty-eight years after her death (1897–1925), with remarkably swift progress through each stage.
The longest causes are those of ancient saints whose documentation was fragmentary, disputed, or lost:
St. Gregory Barbarigo — died 1697, canonized 1960 — 263 years.
Many causes that were opened centuries ago remain in the Venerable or Servant of God stage, waiting either for a verifiable miracle or for the historical research to be completed.
Currently open causes number in the thousands worldwide. Among the most prominent still in progress are those of:
Archbishop Fulton J. Sheen — declared Venerable in 2012, whose beatification has been delayed by canonical complications surrounding the location of his cause. A miracle attributed to his intercession — the resuscitation of a stillborn child in Illinois — was initially approved and then withdrawn for further investigation. The cause continues.
Dorothy Day — founder of the Catholic Worker Movement, declared a Servant of God in 2000, whose cause is being actively pursued by the Archdiocese of New York.
Venerable Pope Pius XII — whose cause has advanced to Venerable but whose canonization has been complicated by continuing historical controversy over his actions during the Second World War — a controversy that ongoing archival research is progressively addressing in his favour.
✠ THE THEOLOGY OF CANONIZATION — WHAT THE CHURCH IS ACTUALLY DECLARING
It is important, finally, to be precise about what canonization actually asserts — and what it does not.
What canonization declares: That the specific person named is definitively in Heaven — in the full, eternal, unmediated presence of God. That their intercession is safe and reliable to invoke. That their life is proposed as a model for the imitation of the faithful. That they may be publicly venerated by the universal Church.
What canonization does not declare: That the canonized person was perfect — the saints had faults, made mistakes, and in some cases sinned gravely before their conversion. Canonization is the declaration of where they are now, not a retroactive perfection of everything they ever did. It does not declare that every miracle attributed to their intercession was genuine — only that the specific miracles verified in their cause meet the Church's standard of evidence. It does not declare that the candidate was the holiest person who ever lived — only that they were holy enough to propose as a model and powerful enough in intercession to invoke.
The infallibility of canonization: Catholic theology holds that solemn canonizations — the formal papal declaration in a canonization ceremony — are protected by papal infallibility. This means that the faithful can hold with certainty that the canonized saint is in Heaven and that the intercession is reliable. The theological basis is the same as for every exercise of infallibility: the Holy Spirit's protection of the Church from defining error in matters of faith and morals. The Church does not claim that the investigation was perfect or that human error was impossible at every stage — she claims that the Holy Spirit protects the final act of solemn definition from error, as He has protected every other solemn definition in the history of the Church's magisterium.
✠ CONCLUSION — THE SAINTS ARE THE CHURCH'S TREASURE
The process of beatification and canonization is long, costly, demanding, and — in the view of those who have followed a cause from its opening to its conclusion — profoundly moving. It is the Church's most sustained act of sustained attention to a single human life: the careful, prayerful, rigorous examination of what one person did with the grace they were given, and the formal, solemn, irreversible declaration that what they did was enough — more than enough — to bring them to the face of God.
The saints are the Church's answer to the question that every human being, in their most honest moments, asks: is it possible? Can a human being actually become what the Gospel promises? Can a person like me — with my failures, my history, my weaknesses — actually arrive at the destination that faith describes?
The calendar of the saints is the Church's answer: yes. Look. Here are the names and the faces and the stories of the people who did it. Not by their own strength, but by the grace of the God who made them and redeemed them and never stopped calling them by name. They were human beings like you. They struggled like you. They fell and rose and fell and rose again. And they arrived. And they are waiting for you. And you can ask them for help on the road.
This is why the Church canonises saints. This is why the process exists. This is why it matters.
"Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with endurance the race that is set before us, looking to Jesus, the founder and perfecter of our faith." — Hebrews 12:1–2
