Epistula ad Philippenses

Now I beseech you all to obey the word of[*](The examples of the martyrs) righteousness, and to endure with all the endurance which you also saw before your eyes, not only in the blessed Ignatius, and Zosimus, and Rufus, but also in others among yourselves, and in Paul himself, and in the other Apostles;

being persuaded that all of these ran not in vain, but in faith and righteousness, and that they are with the Lord in the place which is their due, with whom they also suffered. For they did not love this present world but him who died on our behalf, and was raised by God for our sakes.

Stand fast therefore in these things and follow[*](Perseverance in philanthropy and good works.) the example of the Lord, firm and unchangeable in faith, loving the brotherhood, affectionate to one another, joined together in the truth, forestalling one another in the gentleness of the Lord, despising no man.
