Did Judas really betrat Jesus?
I wonder what your next question will be?
See Matthew 10:4, part of a list of the names of the Twelve:
. . . Simon the Cananite, and Judas Iscariot, who also betrayed Him.
See also Mark 3:19 and John 18:2, 5, which make the same identification.
Why isn’t there an option for “Yes it is in the Bible and the Church tells us so”…???
