For what has happened to you, O wisest of men, and for what do you condemn yourself, that you have cast away the sacred and delightful books which you used once to read to the people (do not be ashamed to hear this), or have hung them up over the chimney, as men do in winter with rudders and hoes, and have applied yourself to salt and bitter ones, and preferred to be called a Professor of Rhetoric rather than of Christianity? I, thank God, would rather be the latter than the former. Do not, my dear friend, do not let this be longer the case, but, though it is full late, become sober again, and come to yourself once more, and make your apology to the faithful, and to God, and to His Altars and Sacraments, from which you have withdrawn yourself. And do not say to me in proud rhetorical style, What, was I not a Christian when I practised rhetoric? Was I not a believer when I was engaged among the boys? And perhaps you will call God to witness. No, my friend, not as thoroughly as you ought to have been, even if I grant it you in part. What of the offence to others given by your present employment -- to others who are prone naturally to evil -- and of the opportunity afforded them both to think and to speak the worst of you? Falsely, I grant, but where was the necessity? For a man lives not for himself alone but also for his neighbour; nor is it enough to persuade yourself, you must persuade others also. If you were to practise boxing in public, or to give and receive blows in the theatre, or to writhe and twist yourself shamefully, would you speak of yourself as having a temperate soul? Such an argument does not befit a wise man; it is frivolous to accept it. If you make a change I shall rejoice even now, said one of the Pythagorean philosophers, lamenting the fall of a friend; but, he wrote, if not you are dead to me. But I will not yet say this for your sake. Being a friend, he became an enemy, yet still a friend, as the Tragedy says. But I shall be grieved (to speak gently), if you do neither yourself see what is right, which is the highest method of all, nor will follow the advice of others, which is the next. Thus far my counsel. Forgive me that my friendship for you makes me grieve, and kindles me both on your behalf and on behalf of the whole priestly Order, and I may add on that of all Christians. And if I may pray with you or for you, may God who quickeneth the dead aid your weakness.
