“YOU MUST all follow the lead of the bishop, as Jesus Christ followed that of the Father; follow the presbytery as you would the Apostles; reverence the deacons as you would God’s commandment. Let no one do anything touching the Church, apart from the bishop. Let that celebration of the Eucharist be considered valid which is held under the bishop or anyone to whom he has committed it. Where the bishop appears, there let the people be, just as where Jesus Christ is, there is the Catholic Church. It is not permitted without authorization from the bishop either to baptize or to hold an agape; but whatever he approves is also pleasing to God. Thus everything you do will be proof against danger and valid.”
~St. Ignatius of Antioch (born 35 or 50 — martyred between 98 to 117): Letter to the Smyrnaeans, 8.
