"The Epistles of Ignatius which were sent to us by him, and others which we had by us, we send you as requested. They are enclosed herewith. You will be able to benefit greatly from them. For they are conducive to faith and patience and to every kind of edification pertaining to our Lord."
- Polycarp, Bishop of Smyrna (Epistle to the Philippians 13, 2; cited in Quasten, Vol. 1, p. 73)
