"Follow the bishop, all of you, as Jesus Christ follows his Father, and the presbyterium as the Apostles. As for the deacons, respect them as the Law of God. Let no one do anything with reference to the Church without the bishop. Only that Eucharist may be regarded as legitimate which is celebrated with the bishop or his delegate presiding. Where the bishop is, there let the community be, just as where Jesus Christ is, there is the Catholic Church. Without the bishop, you are allowed neither to baptize nor to hold an agape celebration. Whatever he approves is fine in God's sight so that all that is done may be legitimized and certain. It is reasonable to start being sensible again and, while there is still time, to repent and come back to God. It is good to honor God and the bishop. The one who honors the bishop will be honored by God. The one who does something and hides it from the bishop serves the Devil."
-St. Ignatius of Antioch, Letter to the Smyrnaeans.
