Note 4 at Lu 6:16: Judas, the brother of James, son of Alphaeus, was also known as Lebbaeus and Thaddaeus (Mt 10:3), both of which indicate "a beloved child." He is identified as Lebbaeus and Thaddaeus in Mt 10:3; Thaddaeus in Mr 3:18; Judas, the brother of James, in Lu 6:16 and Ac 1:13; and "Judas...not Iscariot" in Joh 14:22. Four of these five times identify him as one of the twelve apostles.

He is quoted only once in Scripture in Joh 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.
