3 Let us not therefore accuse riches, nor revile poverty absolutely, but those who do not will to use these virtuously; for the things themselves lie in the middle. But as I was saying (for it is good to return to the former subject), both rich and poor enjoy the benefit of the medicines administered here with the same boldness and freedom; and often the poor with more earnestness. For the special excellence of the medicines is not this only, that they heal souls, that their virtue is not destroyed by length of time, that they are not worsted by any disease, that the benefit is publicly offered gratuitously, that the healing treatment is on a footing of equality both for rich and poor— but they have another quality also not inferior to these good points.
Pray of what character is this? It is that we do not publicly expose those who come to this surgery. For they who go off to the surgeries of the outside world, have many who examine their wounds, and unless the physician have first uncovered the sore, he does not apply the dressing; but here not so, but seeing as we do innumerable patients, we go through the medical treatment of them in a latent manner. For not by dragging into publicity those who have sinned do we thus noise abroad the sins committed by them; but after putting forth our teaching, as common to all, we leave it entirely to the conscience of the hearers; so that each may draw to himself from what is said the suitable medicine for his own wound.
For there proceeds the word of doctrine from the tongue of the speaker, containing accusation of wickedness, praise of virtue, blame of lewdness, commendation of chasteness, censure of pride, praise of gentleness, just as a medicine of varied and manifold ingredients, compounded from every kind; and to take what is applicable to himself and salutary is the part of each of the hearers. The word then issues openly, and settling into the conscience of each, secretly both affords the healing treatment which comes from it, and before the malady has been divulged, has often restored health.
