Epistles of Ignatius

Keep yourself pure as the dwelling place of God. You are the temple of Christ. You are the instrument of the Spirit. You know how I have raised you. Although I am the least of men, seek to follow me; be an imitator of my conduct. I do not glory in the world, but in the Lord. I exhort Hero, my son: "Let him who glories, glory in the Lord." May I find joy in you, my dear son, whose guardian may be the only unbegotten God, and the Lord Jesus Christ! Do not believe everyone; do not place confidence in all; nor let anyone deceive you with flattery. For many are the ministers of Satan, and "he who is quick to believe is light of heart."
