(Saint) Pope (September 9) (8th century) Of Syrian parentage, but born at Palermo in Sicily, Saint Sergius I ruled the Church from A.D. 687 to A.D. 701. He bravely resisted the encroachments of the Emperors of Constantinople, and rejected their false Synod of A.D. 691, known as the Trullanum or Fifth-Sixth. He sent Saints Chilian, Swithbert, Willibrord and others as missionaries to the heathens of Germany. To him is attributed the introduction of the Agnus Dei into the Canon of the Mass.
