Sometimes called Levi or Thaddaeus (some English translations call him 'Judas'), St. Jude was the brother of St. James and son of St. Joseph Betrothed to the Theotokos. He protested along with Simon and Hosea when the elderly Joseph wanted to leave a portion of his estate to Jesus upon his death. He was often called 'brother of James' out of humility and shame for he did not believe in Christ at first, yet St. James did.
He was one of the twelve Great Apostles (not to be confused with the Thaddeus of the Seventy Apostles) and after the Acension he preached the Gospel in Judea, Samaria, Galilee, Idumea, Syria, Arabia, Mesopotamia, and Armenia. While preaching in the area around Ararat he was captured by pagans, crucified and killed by being shot with arrows. The Church remembers St. Jude on June 19 and has canonized his epistle in the Holy Scriptures.
