XXXVIII. But learn the more excellent way, which Paul shows for salvation. “Love seeks not her own,” but is diffused on the brother. About him she is fluttered, about him she is soberly insane. “Love covers a multitude of sins.” “Perfect love casts out fear.” “Vaunts not itself, is not puffed up; rejoices not in iniquity, but rejoices in the truth; bears all things, believes all things, hopes all things, endures all things. Love never fails. Prophecies are done away, tongues cease, gifts of healing fail on the earth. But these three abide, Faith, Hope, Love. But the greatest of these is Love.” And rightly. For Faith departs when we are convinced by vision, by seeing God. And Hope vanishes when the things hoped for come. But Love comes to completion, and grows more when that which is perfect has been bestowed. If one introduces it into his soul, although he be born in sins, and has done many forbidden things, he is able, by increasing love, and adopting a pure repentance, to retrieve his mistakes. For let not this be left to despondency and despair by you, if you learn who the rich man is that has not a place in heaven, and what way he uses his property.
XXXIX. If one should escape the superfluity of riches, and the difficulty they interpose in the way of life, and be able to enjoy the eternal good things; but should happen, either from ignorance or involuntary circumstances, after the seal and redemption, to fall into sins or transgressions so as to be quite carried away; such a man is entirely rejected by God. For to every one who has turned to God in truth, and with his whole heart, the doors are open, and the thrice-glad Father receives His truly repentant son. And true repentance is to be no longer bound in the same sins for which He denounced death against Himself, but to eradicate them completely from the soul. For on their extirpation God takes up His abode again in you. For it is said there is great and exceeding joy and festival in the heavens with the Father and the angels when one sinner turns and repents. Wherefore also He cries, “I will have mercy, and not sacrifice.” “I desire not the death, but the repentance of the sinner.” “Though your sins be as scarlet wool, I will make them white as snow; though they be blacker than darkness, I will wash and make them like white wool.” For it is in the power of God alone to grant the forgiveness of sins, and not to impute transgressions; since also the Lord commands us each day to forgive the repenting brethren. “And if we, being evil, know to give good gifts,” much more is it the nature of the Father of mercies, the good Father of all consolation, much pitying, very merciful, to be long-suffering, to wait for those who have turned. And to turn is really to cease from our sins, and to look no longer behind.
XL. Forgiveness of past sins, then, God gives; but of future, each one gives to himself. And this is to repent, to condemn the past deeds, and beg oblivion of them from the Father, who only of all is able to undo what is done, by mercy proceeding from Him, and to blot out former sins by the dew of the Spirit. “For by the state in which I find you will I judge,” also, is what in each case the end of all cries aloud. So that even in the case of one who has done the greatest good deeds in his life, but at the end has run headlong into wickedness, all his former pains are profitless to him, since at the catastrophe of the drama he has given up his part; while it is possible for the man who formerly led a bad and dissolute life, on afterwards repenting, to overcome in the time after repentance the evil conduct of a long time. But it needs great carefulness, just as bodies that have suffered by protracted disease need regimen and special attention. Thief, do you wish to get forgiveness? steal no more. Adulterer, burn no more. Fornicator, live for the future chastely. You who has robbed, give back, and give back more than you took. False witness, practice truth. Perjurer, swear no more, and extirpate the rest of the passions, wrath, lust, grief, fear; that you may be found at the end to have previously in this world been reconciled to the adversary. It is then probably impossible all at once to eradicate inbred passions; but by God's power and human intercession, and the help of brethren, and sincere repentance, and constant care, they are corrected.
XLI. Wherefore it is by all means necessary for you, who art pompous, and powerful, and rich, to set over yourself some man of God as a trainer and governor. Reverence, though it be but one man; fear, though it be but one man. Give yourself to hearing, though it be but one speaking freely, using harshness, and at the same time healing. For it is good for the eyes not to continue always wanton, but to weep and smart sometimes, for greater health. So also nothing is more pernicious to the soul than uninterrupted pleasure. For it is blinded by melting away, if it remain unmoved by bold speech. Fear this man when angry; be pained at his groaning; and reverence him when making his anger to cease; and anticipate him when he is deprecating punishment. Let him pass many sleepless nights for you, interceding for you with God, influencing the Father with the magic of familiar litanies. For He does not hold out against His children when they beg His pity. And for you he will pray purely, held in high honour as an angel of God, and grieved not by you, but for you. This is sincere repentance. “God is not mocked,” nor does He give heed to vain words. For He alone searches the marrow and reins of the heart, and hears those that are in the fire, and listens to those who supplicate in the whale's belly; and is near to all who believe, and far from the ungodly if they repent not.
XLII. And that you may be still more confident, that repenting thus truly there remains for you a sure hope of salvation, listen to a tale, which is not a tale but a narrative, handed down and committed to the custody of memory, about the Apostle John. For when, on the tyrant's death, he returned to Ephesus from the isle of Patmos, he went away, being invited, to the contiguous territories of the nations, here to appoint bishops, there to set in order whole Churches, there to ordain such as were marked out by the Spirit.
Having come to one of the cities not far off (the name of which some give), and having put the brethren to rest in other matters, at last, looking to the bishop appointed, and seeing a youth, powerful in body, comely in appearance, and ardent, said, “This (youth) I commit to you in all earnestness, in the presence of the Church, and with Christ as witness.” And on his accepting and promising all, he gave the same injunction and testimony. And he set out for Ephesus. And the presbyter taking home the youth committed to him, reared, kept, cherished, and finally baptized him. After this he relaxed his stricter care and guardianship, under the idea that the seal of the Lord he had set on him was a complete protection to him. But on his obtaining premature freedom, some youths of his age, idle, dissolute, and adepts in evil courses, corrupt him. First they entice him by many costly entertainments; then afterwards by night issuing forth for highway robbery, they take him along with them. Then they dared to execute together something greater. And he by degrees got accustomed; and from greatness of nature, when he had gone aside from the right path, and like a hard-mouthed and powerful horse, had taken the bit between his teeth, rushed with all the more force down into the depths. And having entirely despaired of salvation in God, he no longer meditated what was insignificant, but having perpetrated some great exploit, now that he was once lost, he made up his mind to a like fate with the rest. Taking them and forming a band of robbers, he was the prompt captain of the bandits, the fiercest, the bloodiest, the cruelest.
