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. How great must be the sin beside which seduction and adultery are insignificant? Miserable wretch that you are! When you enter the cave wherein the Son of God was born, where truth sprang out of the earth and the land did yield her increase, it is to make an assignation. Have you no fear that the babe will cry from the manger, that the newly delivered virgin will see you, that the mother of the Lord will behold you?
The angels cry aloud, the shepherds run, the star shines down from heaven, the wise men worship, Herod is terrified, Jerusalem is in confusion, and meantime you creep into a virgin's cell to seduce the virgin to whom it belongs. I am filled with consternation and a shiver runs through me, soul and body, when I try to set before your eyes the deed that you have done. The whole church was keeping vigil by night and proclaiming Christ as its Lord; in one spirit though in different tongues the praises of God were being sung.
Yet you were squeezing your love-notes into the openings of what is now the altar, as it was once the manger, of the Lord, choosing this place in order that your unhappy victim might find and read them when she came to kneel and worship there. Then you took your place among the singers, and with impudent nods communicated your passion to her.
