Vic,
How've ya been? I've been moving.
Interesting post. Your source is not scholarly, however, as it is clearly agenda-driven. Maybe that's inevitable, since honest scholars of religion seem to either start with an agenda or have one thrust upon them.
Since we share this hobby, I'd like to suggest a source to you. Xoroaster is a bible scholar who is on a quest of discovery, and he's essentially videoing that quest. I think you might find his work interesting. He certainly touches on things like Greek influence on the story of Jesus, especially with regard to Homer. Xoroaster will even cite his sources, and he's email friendly.
Try this one for a starter: http://www.youtube.com/watch?v=r-jw1jml5kM
His YouTube page has many such videos.
The Greek influence on Christianity is a compelling topic. The earliest Gospels were written in Greek, decades after the Jesus story originated. The Greek scribes were well aware of many godmen with certain powers and qualities such as virgin birth (really quite common among the gods), water-to-wine, the fish and loaves stuff, raising the dead, casting out demons, walking on water, son of god claim, crucifixion, and resurrection, to name a few. It's not out of the question that the Greeks borrowed a bit from here, a bit from there, to create a unique character whose several mystical qualities are anything but unique.
I presume you're up to speed with Bart Ehrman?
