Didache

Thou shalt not long for division, but shalt bring those who contend to peace. Thou shalt judge righteously, thou shalt not respect persons in reproving for transgressions. Thou shalt not be undecided whether it shall be or no.

Thou shalt hate all hypocrisy and everything which is not pleasing to the Lord. Do thou in no wise forsake the commandments of the Lord; but thou shalt keep what thou hast received, neither adding thereto nor taking away therefrom. In the church thou shalt acknowledge thy transgressions, and thou shalt not come near for thy prayer with an evil conscience.
