These are the Two Great Commandments that contain the whole law of God
I. You shall love the Lord your God with your whole heart, and with your whole soul, and with your whole mind, and with your whole strength
II. You shall love your neighbor as Yourself.
To love God, our neighbor, and ourselves, we must keep the commandments of God and of the Church, and perform the spiritual and corporal works of mercy.
