"Make certain, therefore, that you all observe one common Eucharist; for there is but one Body of Our Lord Jesus Christ, and but one cup of union with His Blood, and one single altar of sacrifice-even as also there is but one Bishop, with his clergy and my own fellow-sevitors the deacons. This will insure that all your doings are in full accord with the will of God."-St. Ignatius of Antioch c.35-107)
