yourmomma - No if you read my posts in this thread you will see that nobody is defending the film although fulltimestudent did post an interesting rebuttal of the video in the OP.
The problem is we have two extreme positions - there are those who see evidence of pagan influence in the gospels in every verse and on the other hand there are biblical literalists like Christ Alone who is so wedded to the concept of inerrancy he won't listen to any of it.
The truth lies somewhere in between. Gospel writers did borrow from pagan mythology. They didn't copy those stories verbatim but they did adapt them to show that their god-man was better than all the pagan god-men.
Dionysus is a good example. Contrary to some commentators I am certain Jesus is not closely based on the life of Dionysus, however the particular incident with the wine miracle is an obvious example of pagan influence. The differences in the two accounts do not negate this any more than the differences between Romeo and Juliet and West Side Story prove that Bernstein didn't adapt Shakespeare's play.
When Christ Alone denies the connection because Dionysus miraculously filled three jars while Jesus filled six, it is typical of the lack of objectivity of those who are committed to defend the gospels at any cost.
I already explained a couple of times why I referred to Justin Martyr. In his First Apology he uses the similarity of Jesus' story to pagan mythology concerning the "sons of Jupiter" to reassure the Emperor that they are not teaching anything radically new.
My use of Martyr is in context, but I don't think you have looked carefully enough at what I actually wrote.
There are a few other interesting examples of pagan influence in the gospels. I will see if I can find the details and post them later.
