And to you [priests] also, disciples of our illustrious physician, it is fitting that you should not withhold healing from him who needs healing. Whoever shows his wound to you, give him the medicine of penitence; and whoever is ashamed to show his disease, you shall exhort him not to conceal from you, and when he has revealed to you do not publish it, lest by means of it the innocent should be considered as debtors by enemies and those who hate them
