Symeon was a first cousin of our Lord Jesus Christ. He was the son of Clopas (or Cleopas, also called Alphaeus), the brother of Joseph the Betrothed. He became the second Bishop of Jerusalem, as a successor to James the Brother of God. He ended his life when he was crucified during the reign of Trajan, in 107, at the age of 120.
Apolytikion of Hieromartyr Symeon – First Tone:
We sacredly acclaim thee as Jesus Christ’s kinsman, and as His steadfast Martyr, O all-lauded Hierarch. For bravely hast thou destroyed all deception and kept the faith. Hence, O Symeon, we keep thy holy remembrance on this festive day; and by thy prayers, we are granted the pardon of grievous sins.
