Why do Matthew and Mark list Thaddeus, but Luke another Judas?
The short answer
Because they are the same man. The Thaddeus of Matthew 10:3 and Mark 3:18 is the Judas of Luke 6:16. He probably went by a second name to avoid confusion with Judas Iscariot.
One apostle
Thaddeus in Matthew (10:3) and Mark (3:18) is the same person as the first Judas named in Luke (6:16).
Why two names
This apostle likely had a second name that was often used so he would not be confused with Judas Iscariot. As A Catholic Commentary on Holy Scripture notes, like many people of his time he had several names, and the early Christians naturally avoided the one he shared with the traitor.
