Soggy:
You mean Matthew, who wrote this stuff down decades after the supposed source, Jesus Christ, died?
actually, Matthew used Mark and another source (usually called "Q") to
write his gospel, as well as information unique to Matthew.
Mark was written first.
Like Matthew, Luke used Mark, Q, and information unique to Luke.
by the time John was written (the last of the Canonical Gospels to be
written), things were all over the place, and John isn't even considered
a synoptic gospel (like Mark, Matthew, and Luke).
Read Mark in a sitting, and then John in a sitting, and you will see
the tremendous leap in the "Jesus Message" that has taken place,
already within the first 70 years of Jesus' death.
one of the earliest gospels, Thomas, is not a cannonical gospel
because by the time the canon was decided upon, Christianity had chaged
so much that the church fathers felt the early gospel was "alien"
to Christianity.
now, the gospel of Thomas handn't changed. what had changed
was the views of Christianity around.
a fascinating subject, and one i wish i knew more about
