The Author of the Letter
nMost of 7 listed are pretty obscure.
nThe name was quite popular.
nThe author of our letter was probably:
nJude, of James (Luke 6:16)
nJude, bro of James and Jesus (Matt 13:55)
nThe second of these seems best, though Catholics identify the two.
nI donŐt, as JesusŐ brothers did not believe in him during his ministry.
