From the Office of Readings for Sept. 28: St Polycarp's Epistle to the Philippians

Let us run in faith and holiness

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.

I am greatly grieved for Valens, who was once a presbyter among you, because he so little understands the place that was given him [in the Church]. I exhort you, therefore, that you abstain from covetousness, and that you be chaste and truthful. "Abstain from every form of evil." For if a man cannot govern himself in such matters, how shall he enjoin them on others? If a man does not keep himself from covetousness, he shall be defiled by idolatry, and shall be judged as one of the heathen. But who of us are ignorant of the judgment of the Lord? "Do we not know that the saints shall judge the world?" as Paul teaches. But I have neither seen nor heard of any such thing among you, in the midst of whom the blessed Paul laboured, and who are commended in the beginning of his Epistle. For he boasts of you in all those Churches which alone then knew the Lord; but we [of Smyrna] had not yet known Him. I am deeply grieved, therefore, brethren, for him (Valens) and his wife; to whom may the Lord grant true repentance! And be then moderate in regard to this matter, and "do not count such as enemies," but call them back as suffering and straying members, that you may save your whole body. For by so acting you shall edify yourselves.
