Library Ignatius of Antioch Epistles (Middle Recension)
Polycarp, Chapter 4: Exhortations
Let not widows be neglected. Be, after the Lord, their protector and friend. Let nothing be done without your consent; neither do anything without the approval of God, which indeed you do not, inasmuch as you are steadfast. Let your assembling together be of frequent occurrence: seek after all by name. Do not despise either male or female slaves, yet neither let them be puffed up with conceit, but rather let them submit themselves the more, for the glory of God, that they may obtain from God a better liberty. Let them not long to be set free [from slavery] at the public expense, that they be not found slaves to their own desires.
