1 Kings 15:11

Furthermore, with respect to the repentance which occurs in His conduct, you interpret it with similar perverseness just as if it were with fickleness and improvidence that He repented, or on the recollection of some wrong-doing; because He actually said, “It repenteth me that I have set up Saul to be king,” very much as if He meant that His repentance savoured of an acknowledgment of some evil work or error. Well, this is not always implied. For there occurs even in good works a confession of repentance, as a reproach and condemnation of the man who has proved himself unthankful for a benefit. …

But because God foresaw all things, and was therefore not ignorant that man also would fall, we ought to consider this holy city in connection with what God foresaw and ordained, and not according to our own ideas, which do not embrace God’s ordination. For man, by his sin, could not disturb the divine counsel, nor compel God to change what He had decreed; for God’s foreknowledge had anticipated both, that is to say, both how evil the man whom He had created good should become, and what good He Himself should even thus derive from him. For though God is said to change His determinations (so that in a tropical sense the Holy Scripture says even that God repented), this is said with reference to man’s expectation, or the order of natural causes, and not with reference to that which the Almighty had foreknown that He would do. …

11. “The Lord hath made a faithful oath unto David, and He shall not repent” ( ver. 11 ). What meaneth, “hath made an oath”? Hath confirmed a promise through Himself. What meaneth, “He shall not repent”? He will not change. For God suffereth not the pain of repentance, nor is He deceived in any matter, so that He would wish to correct that wherein He hath erred. But as when a man repents of anything, he wisheth to change what he hath done; thus where thou hearest that God repenteth, look for an actual change. God doth it differently from thee, although He calleth it by the name of repentance; for thou dost it, because thou hadst erred; while He doth it, because He avengeth, or freeth. …

1. Of old, when it had repented the Lord that he had anointed Saul to be king over Israel, we are told that Samuel mourned for him; and again, when Paul heard that there was fornication among the Corinthians and such fornication as was not so much as named among the gentiles, he besought them to repent with these tearful words: “lest, when I come again, my God will humble me among you and that I shall bewail many which have sinned already and have not repented of the uncleanness and fornication and lasciviousness which they have committed.” If an apostle or a prophet, themselves immaculate, could speak thus with a clemency embracing all, how much more earnestly should a sinner like me plead with a sinner like you. …

4. Have mercy I beseech you upon your soul. Consider that God’s judgment will one day overtake you. Remember by what a bishop you were ordained. The holy man was mistaken in his choice; but this he might well be. For even God repented that he had anointed Saul to be king. Even among the twelve apostles Judas was found a traitor. And Nicolas of Antioch, a deacon like yourself, disseminated the Nicolaitan heresy and all manner of uncleanness. I do not now bring up to you the many virgins whom you are said to have seduced, or the noble matrons who have suffered death because violated by you, or the greedy profligacy with which you have hied through dens of sin. For grave and serious as such sins are in themselves, they are trivial indeed when compared with those which I have now to narrate. …

It is impossible for us briefly to run through everything. For who could count up almost all the patriarchs and numberless saints, some of whom for the preservation of life, others out of desire for a blessing, others out of pity, others to conceal some secret, others out of zeal for God, others in searching for the truth, became, so to speak, patrons of lying? And as all cannot be enumerated, so all ought not to be altogether passed over. For piety forced the blessed Joseph to raise a false charge against his brethren even with an oath by the life of the king, saying: “Ye are spies: to see the nakedness of the land are ye come;” and below: “send,” says he, “one of you, and bring your brothers hither: but ye shall be kept here until your words are made manifest whether ye speak the truth or no: but if not, by the life of Pharaoh, ye are spies.” For if he had not out of pity alarmed them …
