Hey guys, I'm preparing to preach on Acts 1:12-26 this week, and had always assumed the men in the upper room were all of the original apostles, save Judas of course. But I noticed in Acts 1 there is a man listed as Judas son of James, who did not appear in the original listing of the 12 (Matthew 10). Did Thaddeus die, and have to be replaced? Did he change his name? Do we have any recourse besides speculation on this? Any other Scriptures that might help solve this mystery?
