I.

Cyprian to Caecilius his brother, greeting. Although I know, dearest brother, that very many of the bishops who are set over the churches of the Lord by divine condescension, throughout the whole world, maintain the plan of evangelical truth, and of the tradition of the Lord, and do not by human and novel institution depart from that which Christ our Master both prescribed and did; yet since some, either by ignorance or simplicity in sanctifying the cup of the Lord, and in ministering to the people, do not do that which Jesus Christ, our Lord and God, the founder and teacher of this sacrifice, did and taught, I have thought it as well a religious as a necessary thing to write to you this letter, that, if any one is still kept in this error, he may behold the light of truth, and return to the root and origin of the tradition of the Lord. Nor must you think, dearest brother, that I am writing my own thoughts or man's; or that I am boldly assuming this to myself of my own voluntary will, since I always hold my mediocrity with lowly and modest moderation. But when anything is prescribed by the inspiration and command of God, it is necessary that a faithful servant should obey the Lord, acquitted by all of assuming anything arrogantly to himself, seeing that he is constrained to fear offending the Lord unless he does what he is commanded.
