Didache 15

Now appoint for yourselves bishops and deacons worthy of the Lord, men meek and not ava- ricious, and upright and proved; for they, too, render you the service of the prophets and teachers. Despise them not, therefore; for they are the ones who are honored of you, together with the prophets and teachers. And reprove one another, not in anger but in peach, as ye have it in the gospel; and to every one who erreth against another, let no one speak, nor let him hear any- thing from yo, until he repent. But your prayers and your alms and all your deeds so do ye, as ye have it in the gospel of our Lord.
