Little is known of Thaddaeus, apart from his appointment as one of Jesus’ twelve apostles. From the comparison of the lists of names in the four Gospels, it seems that ‘Thaddaeus’ was another name for Judas the son of James (Matthew 10:3; Mark 3:18; Luke 6:16; John 14:22; Acts 1:13). (In some versions he is called the brother of James and given an alternative name, Lebbaeus.)
