Ignatius of Antioch... you... are stones of the temple of the Father, prepared for the Father's building, and drawn up on high by the instrument of Jesus Christ, which is the Cross (cf. Jn. 12:32), making use of the Holy Spirit as a rope, while your faith was the means by which you ascended, and your love the way which led up to God. You, therefore, as well as all your fellow-travelers, are God-bearers, temple-bearers, Christ-bearers, bearers of holiness, adorned in all respects with the commandments of Jesus Christ.

It is not lawful either to baptize or to celebrate a love feast without the bishop, but whatever he approves of, that is also pleasing to God.
