The Epistle of Ignatius to the Ephesians (Short Version)

For some are in the habit of carrying around the name [of Jesus Christ] in wicked guile, while yet they practice things unworthy of God, whom you must flee from as you would wild beasts. For they are ravening dogs, who bite secretly, against whom you must be on your guard, inasmuch as they are men who can scarcely be cured. There is one Physician who possesses both flesh and spirit; both made and not made; God existing in flesh; true life in death; both of Mary and of God; first possible and then impossible,—even Jesus Christ our Lord.
