Matthew and Luke were written later still, using Mark (and perhaps Q) as a reference. John was written even later; you can clearly see that xtianity had evolved considerably by the time it was written.

What can we tell from this table, class?  First, there is not even
one book undisputedly written by a claimed eyewitness to Jesus'
"resurrection." Second, the earliest work with an undisputed
date is 50 AD (some 20 years after Jesus' death).  Even the
earliest possible date for a highly disputed work is 15 years
later than Jess died.  Would such "stand up in court" as you and
Al claim?  Doubtful in the EXTREME, Mikey.  You wouldn't need
Johnny Cochrane to get this stuff tossed out.
For lagniappe, the fates of the 12-1/2 apostles:
Judas Iscariot:    Died mysteriously, definitely not martyred.
Thomas:            Either lived out his life peacefully in Parthia, or
                   was martyred in India -- no confirming evidence
                   either way.
Peter (Simon):     Possibly martyred in Rome -- evidence is slight.
Matthew:           Unknown.
John:              Unknown.
Thaddaeus (Jude):  Unknown.
Bartholomew:       Unknown.
Philip:            Unknown.
Simon:             Unknown.
Andrew:            Traditionally martyred -- no backing evidence.
Matthias:          Unknown.
James (greater):   Martyred (according to bible and legend, anyway).
James (lesser):    Stoned, according to Josephus.
