John Chrysostom — on 2Tim 4:2 (Homily on 2 Timothy 9)

“"Preach the word: be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine." What means "in season, out of season"? That is, have not any limited season: let it always be thy season, not only in peace and security, and when sitting in the Church. Whether thou be in danger, in prison, in chains, or going to thy death, at that very time reprove. Withhold not rebuke, for reproof is then most seasonable, when thy rebuke will be most successful, when the reality is proved. "Exhort," he says. After the manner of physicians, having shown the wound, he gives the incision, he applies the plaster. For if you omit either of these, the other becomes useless. If you rebuke without convicting, you will seem to be rash, and no one will tolerate it, but after the matter is proved, he will submit to rebuke: before, he will be headstrong. And if you convict and rebuke, but vehemently, and do not apply exhortation, all your labor will be lost. For conviction is intolerable in itself if consolation be not mingled with it. As if incision, though salutary in itself, have not plenty of lenitives to assuage the pain, the patient cannot endure cutting and hacking, so it is in this matter. "With all longsuffering and doctrine." For he that reproves is required to be longsuffering, that he may not believe hastily, and rebuke needs consolation, that it may be received as it ought. And why to "longsuffering" does he add "doctrine"? "Not as in anger, not as in hatred, not as insulting over him, not as having caught an enemy. Far be these things from thee." But how? As loving as sympathizing with him, as more distressed than himself at his grief, as melted at his sufferings? "With all longsuffering and doctrine." No ordinary teaching is implied.”
