Epistle to Polycarp

Having obtained good proof that your mind is fixed in God as upon an immoveable rock, I loudly glorify [His name] that I have been thought worthy [to behold] your blameless face, which may I ever enjoy in God! I entreat you, by the grace with which you are clothed, to press forward in your course, and to exhort all that they may be saved. Maintain your position with all care, both in the flesh and spirit. Have a regard to preserve unity, than which nothing is better. Bear with all, even as the Lord does with you. Support all in love, as also you do. Give yourself to prayer without ceasing. Implore additional understanding to what you already have. Be watchful, possessing a sleepless spirit. Speak to every man separately, as God enables you. Bear the infirmities of all, as being a perfect athlete [in the Christian life]: where the labour is great, the gain is all the more.
