The Epistles of Ignatius

Moreover, it is in accordance with reason that we should return to soberness [of conduct], and, while yet we have opportunity, exercise repentance towards God. It is well to reverence both God and the bishop. He who honours the bishop has been honoured by God; he who does anything without the knowledge of the bishop, does [in reality] serve the devil. Let all things, then, abound to you through grace, for ye are worthy. Ye have refreshed me in all things, and Jesus Christ [shall refresh] you. Ye have loved me when absent as well as when present. May God recompense you, for whose sake, while ye endure all things, ye shall attain unto Him.
