James the Just, or a variation of James, brother of the Lord (Latin: Iacobus from Hebrew: יעקב, Ya'aqov and Ancient Greek: Ἰάκωβος, Iákōbos, can also be Anglicized as "Jacob"), was, according to the New Testament, a brother of Jesus. He was the first leader of the Church of Jerusalem. Traditionally, it is believed he was martyred either in 62 AD by being stoned to death on the order of High Priest Ananus ben Ananus, or in 69 AD by being thrown off the pinnacle of the Temple by scribes and Pharisees and then clubbed to death. James, Joses, Simon, and Judas are mentioned as the brothers of Jesus as well as two or more unnamed sisters. (See Matthew 13:55; Mark 6:3.)
Catholics, Orthodox, and some Protestants teach that James, along with others named in the New Testament as brothers of Jesus, were not the biological children of Mary, mother of Jesus, but were cousins of Jesus, or step-brothers from a previous marriage of Joseph (as related in the non-canonical Gospel of James). Others consider James to be the son of Mary and Joseph.
