Jude Thaddeus
the other Judas of the Twelve
Who was Jude Thaddeus?
- He was one of the Twelve: Matthew and Mark call him Thaddeus. Tradition identifies him with Luke’s Judas “of James.” Matthew 10:3; Luke 6:16
- The Gospel of John tells that a Judas, “not the Iscariot,” asked Jesus a question at the Last Supper. Tradition says it was he. John 14:22
No verse says that Thaddeus and Luke’s Judas “of James” are the same person. Tradition explains it by comparing the lists of the Twelve. The Douay-Rheims reads “Jude, the brother of James”; the original says only “Judas of James.” Tradition also teaches that the Judas at the Last Supper is Thaddeus. The verse only says “Judas, not the Iscariot.” And the note in the U.S. bishops’ Bible says it could be Thomas.
- The name
- “Judas” comes from Judah, which in Hebrew means “praised.” The meaning of “Thaddeus” is not certain: perhaps it comes from the Aramaic word for “breast,” and would mean “great-hearted.” Catholic Encyclopedia (1913), “Judas Iscariot”; Benedict XVI, general audience of October 11, 2006
- Also called
- Thaddeus Matthew 10:3; Mark 3:18 · Judas of James (Tradition identifies them) Luke 6:16; Acts 1:13 · “Judas, not the Iscariot” (according to Tradition) John 14:22
- Feast day
- October 28: Saints Simon and Jude, Apostles
