Note 4 at Lk. 6:16: Judas, the brother of James, son of Alphaeus, was also known as Lebbaeus and Thaddaeus (Mt. 10:3), both names of which indicated "a beloved child." He is identified as Lebbaeus and Thaddaeus in Matthew 10:3, Thaddaeus in Mark 3:18, Judas, the brother of James in Luke 6:16 and Acts 1:13, and "Judas . . . not Iscariot" in John 14:22. Four of these five times identify him as one of the twelve apostles.

He is quoted only once in scripture in John 14:22 asking Jesus how He would manifest Himself to His disciples and not to the world.

Tradition says he worked for the Lord in Persia and was eventually beaten to death by pagan priests.
