James the Less is a figure of early Christianity, one of the Twelve chosen by Jesus. He is also called "the Minor", "the Little", "the Lesser", or "the Younger", according to translation. He is not to be confused with James, son of Zebedee. He is identified by some as James, the Lord's brother, thought of by St. Jerome and those who followed him as really the cousin of Jesus. James the Less was traditionally commemorated with St. Philip on May 1st in the Western calendars.
James the Less is identified with James the brother of Jesus. Jerome concluded that James "the brother of the Lord" is the same as James the Less. To explain this, Jerome first tells that James the Less must be identified with James, the son of Alphaeus. After that, James the Less being the same as James, the son of Alphaeus, Jerome describes in his work called De Viris Illustribus that James "the brother of the Lord" is the same as James, son of Alphaeus:
The title, "the Less", is used to differentiate James from other people named James. Since it means that he is either the younger or shorter of two, he seems to be compared to one other James. In the lists of the twelve apostles in the synoptic Gospels, there are two apostles called James, who are differentiated there by their fathers: James, son of Zebedee, and James, son of Alphaeus. Long-standing tradition identifies James, the son of Alphaeus, as James the Less. James, son of Zebedee, is then called "James the Great". Some propose that Alphaeus was the same man as Cleophas or at least the husband of Mary Clopas. In this regard, Jerome identified James the Less with James, son of Alpheus writing in his work called The Perpetual Virginity of Blessed Mary the following: Papias of Hierapolis, who lived circa 70–163 AD, in the surviving fragments of his work Exposition of the Sayings of the Lord relates that Mary, wife of Alphaeus is mother of James the Less: Therefore, James, son of Alphaeus would be the same as James the Less. In Catholic tradition, James's mother is none other than Mary of Clopas who was among the women at the foot of the Cross of Jesus, weeping. For that reason, and given the fact that the Semitic word for brother is also used for other close relatives, James son of Alpheus is often held as a cousin to Jesus. He is also thought by some to be the brother of Matthew the Apostle, since the father of both was named Alphaeus. ModernBiblical scholars are divided on whether this identification is correct. John Paul Meier finds it unlikely. Amongst evangelicals, the New Bible Dictionary supports the traditional identification, while Don Carson and Darrell Bock both regard the identification as possible, but not certain.
