Saint James was a kinsman of the Lord Jesus, either His half-brother (a son of Joseph by his first wife) or His cousin (a son of Joseph's brother Cleopas). In any case, the Scriptures refer to him as the Lord's brother, as was the idiom of the Jews at that time. He is also known as James the Less and James the Just.
He was the first bishop of Jerusalem, appointed to this position by the Apostles, and served with great holiness and righteousness. One year at Passover, he climbed to the top of the Temple in Jerusalem and proclaimed the divinity of Jesus and His Second Coming. The high priest Ananias had him thrown off the Temple and stoned to death, but James prayed for them until the moment of his death.
His feast is celebrated on October 23.
