St. Jude, known as Thaddaeus, was a brother of St. James the Lesser, and a relative of Jesus. Ancient writers tell us that he preached the Gospel in Judea, Samaria, Idumaea, Syria, Mesopotamia, and Lybia. According to Eusebius, he returned to Jerusalem in the year 62 and assisted at the election of his brother, St. Simeon, as Bishop of Jerusalem.

Little is known about the post-Pentecost life of St. Simon, who had been called a Zealot. He is thought to have preached in Egypt and then to have joined St. Jude in Persia. Here, he was supposedly martyred by being cut in half with a saw, a tool he is often depicted with. However, the 4th-century St. Basil the Great says he died in Edessa, peacefully.
