But look at the men who have those perverted notions about the grace of Jesus Christ which has come down to us, and see how contrary to the mind of God they are. . . . They even abstain from the Eucharist and from the public prayers, because they will not admit that the Eucharist is the self-same body of our Savior Jesus Christ which flesh suffered for our sins, and which the Father of His goodness raised up again.
Ignatius of AntiochLet us therefore be of a reverent spirit, and fear the long-suffering of God, that it tend not to our condemnation.
Ignatius of AntiochFor some are in the habit of carrying about the name in wicked guile, while they still practice things unworthy of God. You must flee these as you would wild beasts. For they are ravening dogs, who bite secretly, against whom you must be on your guard, since they are men who can scarcely be cured.
