Quote: then it doesn't matter if John is alive and well for several years after Jesus meets his death.
Yes...but that is not what the books say.
Mark claims the godboy was baptized and then hightailed it for the "wilderness." Then it claims that after John was arrested jesus went into Galilee preaching the gospel. Before that, he didn't seem to do shit.
Matty makes similar claims. Jesus gets the holy soaking, goes and plays with the devil for a while and then hears John was arrested and picks up the flag. Even more clearly than "mark" it notes that "from that time onward, jesus began to preach."
Luke botches the whole story - dealing with it as a flashback of Antipas' after throwing in jesus' genealogy at a particularly questionable place.
Again, this stuff does matter. If xtians can't get their story straight why should anyone believe anything they say?
