I’m working through the publicly available English texts from the early Church. Polycarp is one of the earliest post apostolic writers. Only one of his letters survive.
Again, two chapters of his letter to the Phillipians at once.
I exhort you all, therefore, to yield obedience to the word of righteousness, and to exercise all patience, such as you have seen [set] before your eyes, not only in the case of the blessed Ignatius, and Zosimus, and Rufus, but also in others among yourselves, and in Paul himself, and the rest of the apostles. [This do] in the assurance that all these have not run in vain, but in faith and righteousness, and that they are [now] in their due place in the presence of the Lord, with whom also they suffered. For they loved not this present world, but Him who died for us, and for our sakes was raised again by God from the dead.
Stand fast, therefore, in these things, and follow the example of the Lord, being firm and unchangeable in the faith, loving the brotherhood, and being attached to one another, joined together in the truth, exhibiting the meekness of the Lord in your intercourse with one another, and despising no one. When you can do good, defer it not, because alms delivers from death. Be all of you subject one to another having your conduct blameless among the Gentiles, that you may both receive praise for your good works, and the Lord may not be blasphemed through you. But woe to him by whom the name of the Lord is blasphemed! Teach, therefore, sobriety to all, and manifest it also in your own conduct.
