For 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.
Ignatius of AntiochMore Ignatius of Antioch quotes
Christianity is not a matter of persuading people of particular ideas, but of inviting them to share in the greatness of Christ. So pray that I may never fall into the trap of impressing people with clever speech, but instead I may learn to speak with humility, desiring only to impress people with Christ himself.
Ignatius of Antioch
