pope
Also known as: Saint Xystus I
St. Sixtus I (born, Rome [Italy]?âdied c. 125, Rome?; feast day April 3) was the pope from approximately 115 to about 125. He succeeded St. Alexander I and ruled the church under the Roman emperor Hadrian. Although authoritative sources vary on the dates of his pontificate, they all agree that he reigned for 9 or 10 years. Sixtusâs martyrdom is unproved. He was succeeded by St. Telesphorus.
