Leviticus 19:2

Renounce we things carnal, that we may at length bear fruits spiritual. Seize the opportu nity, albeit not earnestly desired, yet favourable, of not having any one to whom to pay a debt, and by whom to be (yourself) repaid! You have ceased to be a debtor. Happy man! You have released your debtor; sustain the loss. What if you come to feel that what we have called a loss is a gain? For continence will be a mean whereby you will traffic in a mighty substance of sanctity; by parsimony of the flesh you will gain the Spirit. For let us ponder over our conscience itself, (to see) how different a man feels himself when he chances to be deprived of his wife. He savours spiritually. If he is making prayer to the Lord, he is near heaven. If he is bending over the Scriptures, he is “wholly in them.” If he is singing a psalm, he satisfies himself. …

2. But, moreover, the very interrogation which is put in baptism is a witness of the truth. For when we say, “Dost thou believe in eternal life and remission of sins through the holy Church?” we mean that remission of sins is not granted except in the Church, and that among heretics, where there is no Church, sins cannot be put away. Therefore they who assert that heretics can baptize, must either change the interrogation or maintain the truth; unless indeed they attribute a church also to those who, they contend, have baptism. It is also necessary that he should be anointed who is baptized; so that, having received the chrism, that is, the anointing, he may be anointed of God, and have in him the grace of Christ. Further, it is the Eucharist whence the baptized are anointed with the oil sanctified on the altar. …

Having premised these remarks, let us carefully attend to the passages which he whom we are answering has produced, as if we ourselves had quoted them. “In Deuteronomy, ‘Thou shalt be perfect before the Lord thy God.’ Again, in the same book, ‘There shall be not an imperfect man among the sons of Israel.’ In like manner the Saviour says in the Gospel, Be ye perfect, even as your Father which is in heaven is perfect.’ So the apostle, in his second Epistle to the Corinthians, says: ‘Finally, brethren, farewell. …

4. “Preserve Thou My Soul, for I am holy” ( ver. 2 ). I know not whether any one could say this, “I am holy,” but He who was in the world without sin: He by whom all sins were not committed but remitted. We own it to be His voice saying, “Preserve Thou My Soul, for I am holy;” of course in that form of a servant which He had assumed. For in that was flesh, in that, was also a Soul. For He was not, as some have said, only Flesh and the Word: but Flesh and Soul also, and the Word, and all this, One Son of God, One Christ, One Saviour; in the form of God equal to the Father, in the form of a servant the Head of the Church. When therefore I hear, “for I am holy,” I recognise His voice: yet do I exclude my own? Surely He speaks inseparably from His body when He speaks thus. …

5. Nor may you excuse yourself on the score of your noble station and the responsibilities of wealth. Look at Pammachius and at Paulinus that presbyter of glowing faith both of whom have offered to the Lord not only their riches but themselves. In spite of the devil and his shuffling they have by no means given skin for skin, but have consecrated their own flesh and bones, yea and their very souls unto the Lord. Surely these may lead you to higher things both by their example and by their preaching, that is, by their deeds and words. You are of noble birth, so are they: but in Christ they are made nobler still. You are rich and held in repute, so once were they: but now instead of being rich and held in repute they are poor and obscure, yet, because it is for Christ’s sake, they are really richer and more famous than ever. …

74. Good, then, is the Spirit, but good, not as though acquiring but as imparting goodness. For the Holy Spirit does not receive from creatures but is received; as also He is not sanctified but sanctifies; for the creature is sanctified, but the Holy Spirit sanctifies. In which matter, though the word is used in common, there is a difference in the nature. For both the man who receives and God Who gives sanctity are called holy, as we read: “Be ye holy, for I am holy.” Now sanctification and corruption cannot share the same nature, and therefore the grace of the Holy Spirit and the creature cannot be of one substance.

116. “Be good to me.” “Why dost thou ask what thou hast denied [to Me]? I would have had thee to be good, and I said ‘Be ye holy, for I Myself am holy,’ and thou settest thyself to deny that I am good? Dost thou then look for forgiveness of sins? Nay, none can forgive sins, but God alone. Seeing, then, that to thee I am not the true and only God, I cannot by any means forgive thee thy sins.”
