¥Of our canonical gospels, no more than two had been written when Luke
wrote (Matthew and Mark), possibly only
Matthew.
¥So there were apparently a number of other attempts in existence when
Luke wrote.
¥He does not suggest these present a different Jesus, but rather that
they, too, depend on the testimony of the
eyewitnesses.
¥There is no evidence that any of these attempts survived to be the
gospels mentioned in later
centuries. They were probably displaced very
early on by Matthew, Mark, Luke and John.
