He was supposed to be fully human, so who knows (although I seriously doubt Leanardo heard any more about it than I have). Priests in Jesus' days were married. Catholic Church celibacy came later, and isn't practiced in the East. I don't know if it was important at the time of the Borgias, but certainly it wasn't practiced at the highest levels by a pope or two or three.
Jesus' wedding invitations never appeared in any of the testaments I have read including that of the cult leader Moses David in the early 1970's. I have't heard yet that it popped up in the Dead Sea Scrolls. So it sounds like a work of pure fiction and based on nothing historical other than the fact that some people existed around Jerusalem a couple thousand years ago.
Why the heck not. It's always great sport to ask "what ifs" of important historical figures. The message of Jesus was such that it really isn't crucial to the story whether he was married or not. I personally know of folks getting worked up over this book and this show and to different points of view. I think I'll worry about things more tangible.
No more calls. We have a winner!
Except that it would invalidate some Old Testament prophesies concerning Him if he had been married.
Only if you're into reducing the Savior of the world to a portable pocket Jesus for Ethical Living.
Christians preach "Christ crucified", not "Christ teaching". Christ's crucifixion, including his death, is the "message".
