Pray continually for the rest of humankind as well, that they may find God, for there is in them hope for repentance. Therefore allow them to be instructed by you, at least by your deeds. In response to their anger, be gentle; in response to their boasts, be humble in response to their slander, offer prayers; in response to their errors, be steadfast in the faith; in response to their cruelty, be civilized; do no be eager to imitate them. Let us show by our forbearance that we are their brothers and sisters, and let us be eager to be imitators of the Lord.
-- The Letter of Ignatius to the Ephesians
Much could be said about these magnificent words of instruction, but nothing honestly need be said about them. They are instruction, reminder, rebuke, and encouragement enough.
