"The mind is purified by spiritual knowledge; the spiritual passions of the soul by charity; and the irregular appetites by abstinence and penance." — Saint Serapion's personal rule, as recorded by Socrates Scholasticus
The Man Who Gave Saint Anthony His Hair Shirt
When Saint Anthony the Great lay dying in the desert of Egypt — the father of Christian monasticism, the man whose life Athanasius would write as the template for all monastic biography to follow — he divided the two possessions he had kept through a lifetime of radical poverty. One hair-shirt tunic he left to his friend Athanasius. The other he left to Serapion of Thmuis.
This detail, preserved in Athanasius's Life of Anthony, is a small thing and a significant one. The two men to whom the dying desert father entrusted his last possessions were the two people who had earned the most of his regard: the bishop who was the greatest defender of Trinitarian orthodoxy in the fourth century, and the scholar-bishop who had left the most celebrated school in Christendom to pray in the desert. Anthony apparently found them worth the same recognition.
Serapion of Thmuis is among the most accomplished and least-remembered figures of the fourth-century Church. He directed the Catechetical School of Alexandria — the school that had shaped the intellectual tradition of Eastern Christianity through the minds of Clement and Origen, the most theologically active educational institution in the ancient world. He left it to become a monk. He was drawn from the desert to become a bishop. He was exiled for standing with Athanasius against the Arians. He spent the last years of his life in banishment, in which he died.
He is for the scholar who has discovered that the deepest learning requires more than books. He is for the bishop who has been driven from his see for refusing the demands of imperial power. He is for the friend who knows that standing with the persecuted is the simplest definition of loyalty, and who does it regardless of the cost.
Alexandria, the Greatest School in Christendom, and the Decision to Leave It
The Catechetical School of Alexandria was not merely an institution. It was the intellectual nerve center of the Eastern Church — the place where Greek philosophy and Christian theology had been in productive, sometimes explosive, contact since the late second century, where Clement of Alexandria had begun the project of a genuinely Christian intellectual culture, and where Origen had pushed it to its farthest reaches. To direct this school was to occupy one of the most prestigious positions available to a Christian scholar in the ancient world.
Serapion occupied it. His reputation had been established by a combination of penetrating intelligence and wide learning, both sacred and secular — the scholasticus appellation that Jerome would later give him was the earned recognition of a man who had mastered the curriculum of the age and applied it to the service of the faith. He was, by every available evidence, exactly the kind of mind the school needed: brilliant, disciplined, orthodox, and able to transmit the tradition with both rigor and warmth.
He left.
The sources record no dramatic crisis, no moment of conflict or collapse, no external pressure that forced the decision. Serapion left the school because he had decided that the "science of the saints" — the deep interior knowledge of God that the monastic life made possible — was what his studies had always been pointing toward, and that no amount of additional reading would substitute for what the desert could teach. He withdrew from Alexandria and became, in the language the sources use, "a bright light in the monastic state."
He came under the formation of Anthony the Great — the austere Egyptian hermit whose influence on fourth-century Christianity was mediated primarily through the quality of the people he shaped and the testimony they bore to what proximity to genuine holiness produces. Anthony, according to Athanasius's account, could perceive things at a distance, including things happening in Alexandria during Serapion's visits to the desert; Athanasius records that Anthony would tell him in the desert what was currently occurring in the city, as though reading it from the air. The hair-shirt bequest at Anthony's death was the formal conclusion of a relationship of formation and friendship that had been running for years.
Thmuis, Athanasius, and the Arian Crisis
He was consecrated Bishop of Thmuis sometime before 339. Thmuis was a city of Lower Egypt, in the Nile delta region near Diospolis — a city whose Egyptian name meant "goat" and whose ancient religious life had featured that animal's worship, as Jerome dryly noted. It was not Alexandria. It was not the intellectual summit. It was a diocese that needed a bishop, and Serapion became its bishop and served it well.
But his most important ministry was not parochial. It was the friendship with Athanasius that defined both men's lives during the decades of the Arian crisis.
Athanasius of Alexandria — Bishop of Alexandria, patriarch, the most important orthodox churchman of the fourth century, the man whose name became the adjective for the orthodox position in the Trinitarian controversy (Athanasian) — was fighting, for most of his episcopate, to defend the Nicene definition of Christ's full divinity against an Arian party that had the support of the imperial court. He spent seventeen of his forty-five years as bishop in exile, driven from his see five times by Arian emperors who wanted a more compliant patriarch.
Serapion was with him. In 347 he attended the Council of Sardis as Athanasius's representative, defending him before the assembled bishops. In 356, Athanasius sent Serapion and four other Egyptian bishops on an embassy to the Emperor Constantius — the Arian emperor — to refute the charges the Arian party had brought against the patriarch and to speak in his defense. The embassy did not save Athanasius, who was exiled again; but it demonstrated, in the most public possible forum, where Serapion's allegiances lay.
The consequences were predictable. In 359, the Arian usurper Ptolemaius — installed by the Arian party as a rival patriarch in Alexandria — expelled Serapion from his see. He went into exile. Jerome, writing in the generation after these events, named him "Confessor" — the technical title given to those who suffered for the faith short of martyrdom. The title was accurate: Serapion had been stripped of his see and driven from his diocese because he would not abandon Athanasius or the Nicene faith.
The New Heresy and the Letters That Refuted It
While Athanasius was in hiding and Serapion was in banishment, a new threat appeared in Egypt that neither man had anticipated.
There were Christians, Serapion reported to Athanasius in a letter, who accepted the full divinity of the Son — who confessed with Nicaea that the Son was homoousios with the Father, of the same substance — but who denied the full divinity of the Holy Spirit. They treated the Spirit as a creature, a subordinate being created by the Father, present in sanctifying grace but not sharing in the divine nature. This position would later be called Macedonianism, after the bishop Macedonius who was associated with it; at the moment Serapion was writing, it was a new error without a name.
He informed Athanasius. He asked him to respond.
What Athanasius wrote in response to Serapion's letters — the four Letters to Serapion, composed while Athanasius was in hiding in the Egyptian desert in 359 — was the first formal theological treatise on the Holy Spirit in the history of Christian thought. The letters worked out, for the first time in systematic form, the full argument for the Spirit's divinity: the Spirit proceeds from the Father, acts as God acts, sanctifies in the way that only God can sanctify, and must therefore be understood as fully divine rather than as a creature of the divine. The pneumatology that would find its definitive conciliar statement at Constantinople in 381 was being worked out in letters between a bishop in hiding and a bishop in exile, in the middle of the Arian crisis, against a heresy that had not yet found its name.
Athanasius thought so highly of Serapion that he told him to revise the letters as he saw fit. The invitation to correct the patriarch's own theology is one of the most remarkable testimonies to the quality of Serapion's theological judgment in all of patristic literature.
The Euchologion: The Most Important Prayer Book You Have Never Heard Of
Among Serapion's surviving writings, the most important for the history of Christian worship is the Euchologion — a collection of thirty liturgical prayers discovered in an eleventh-century manuscript of the Great Lavra of Mount Athos by the scholar Dmitrijewskij in 1894 and published for the scholarly world shortly thereafter.
The thirty prayers cover the full range of liturgical life: eighteen prayers related to the Eucharistic liturgy, seven to Baptism and Confirmation, three to Holy Orders, two to the anointing of the sick, one to the burial of the dead. They are the most complete surviving record of Egyptian liturgical practice in the fourth century — a window into what Christian worship looked, sounded, and felt like in the delta of the Nile when the great doctrinal controversies were still being decided.
Among the Eucharistic prayers, two features stand out for liturgical historians. First, the Euchologion contains the earliest certain textual evidence for the Sanctus in the Mass — the Holy, holy, holy Lord that has been sung in every Eucharistic prayer in every rite of the Catholic Church from that day to this. Second, Serapion's epiclesis — the prayer calling down divine power upon the eucharistic elements to effect their transformation — invokes the Logos, the divine Word, rather than the Holy Spirit: "We beseech You, O God of truth, let Your holy Logos come upon this bread that the bread may become the body of the Logos." This is not unorthodox — the Logos is the Second Person of the Trinity, and the prayer is a Eucharistic consecration in the full sense — but it is theologically distinctive, and it has occupied liturgical scholars ever since.
The Euchologion is not a historical curiosity. It is a living document in the sense that the liturgy it preserves is recognizably continuous with the liturgy still celebrated in every Catholic church. The Sanctus that Serapion's congregation sang in the delta of the Nile in the fourth century is the same Sanctus sung at the altar this Sunday. The words have come from very far away.
The Exile and the Death
Serapion died in his banishment, in the fourth century, at a date the sources do not specify precisely — somewhere in the range of 362 to 370. He died away from his diocese, away from his people, in the condition the Roman Martyrology describes with the economy appropriate to a man who had traded comfort for fidelity at every stage of his life: "forced into exile by the enraged Arians, went to heaven."
Jerome, whose intellectual severity made him a demanding judge of his contemporaries, named him Confessor and said of him that he wrote "many useful letters" along with the works on the Psalms and against Manichaeism that are partially preserved. Athanasius, whose letters to Serapion constitute the most important intellectual exchange in the fourth-century pneumatological debate, treated him as a theological equal — the only person to whom he ever gave the authority to revise his own work. Anthony the Great, dying in the desert, divided his last two possessions between Athanasius and Serapion.
Three witnesses. Three of the greatest figures of fourth-century Christianity. All three pointing to the same man, who left the greatest school in Christendom to pray in the desert, was called from the desert to shepherd a city in the Nile delta, and then driven from that city for standing with the faith he had learned in the desert and taught in the school.
His summary of the spiritual life — "The mind is purified by spiritual knowledge; the spiritual passions of the soul by charity; and the irregular appetites by abstinence and penance" — has the compressed quality of a rule composed for people who do not have much time. He had been a director of scholars and a student of hermits, and what he distilled from both was not a program but a diagnosis: know what needs purifying, and apply the appropriate remedy.

Prayer to Saint Serapion the Scholastic
O God, who gave Your servant Serapion the grace to exchange the chair of the scholar for the cell of the monk, and who then drew him from the cell to shepherd a people and defend the faith, grant through his intercession that those who study may not mistake knowledge for wisdom, that those who pray may not mistake solitude for withdrawal from the world's real needs, and that those who are driven from their work for the faith's sake may find in exile the deepening that the work could not provide. Through Christ our Lord. Amen.
