Life and Martyrdom
Side, in the Roman province of Pamphylia on the southern coast of Asia Minor, was the setting of Alexander's ministry as a priest. The sources place his death in the persecution of the emperor Aurelian, whose reign fell between 270 and 275, locating Alexander among the martyrs of the pre-Nicene Church.
When the ruler Antoninus came to Side, he summoned Alexander to be questioned. Asked who he was, Alexander declared that he was a Christian and a priest, a shepherd of Christ's rational flock, and confessed Christ as the Savior of the world. He defended the divinity and resurrection of Christ before his judge and would not offer sacrifice to idols.
The synaxarion describes a sequence of tortures inflicted upon him, among them scourging, the wheel, a vessel of boiling resin and oil, and a fiery furnace, from which the accounts say he emerged unharmed. He was also given over to wild beasts, which the tradition relates did not touch him. After these torments he was put to death by beheading.
