The Epistles of Saint Ignatius (5.pref.sal)

Ignatius, who is also called Theophorus, to the[*] Church of God the Father and of the Lord Jesus Christ, which is in Philadelphia in Asia, which has obtained mercy, and is established in the harmony of God, and rejoices in the Passion of our Lord without doubting, and is fully assured in all mercy in his resurrection; I greet her in the blood of Jesus Christ, which is eternal and abiding joy, especially if men be at one with the bishop, and with the presbyters and deacons, who together with him have been appointed according to the mind of Jesus Christ, and he established them in security according to his own will by his Holy Spirit.
