The Didache

Appoint, therefore, for yourselves, bishops and deacons worthy of the Lord, men meek, and not lovers of money, and truthful and proved; for they also render to you the service of prophets and teachers. Despise them not therefore, for they are your honoured ones, together with the prophets and teachers. And reprove one another, not in anger, but in peace, as ye have it in the Gospel; but to every one that acts amiss against another, let no one speak, nor let him hear aught from you until he repent. But your prayers and alms and all your deeds so do, as ye have it in the Gospel of our Lord.
