"..history is always writ by those who conquered?"

Kinda...

And it is merely a historical accident that Jesus won over Ahura Mazda (Mithraism)in Rome. What there was of the Bible was read/transmitted in 'dockyards' Greek, and Mithra was ahead until Constantine was converted and decreed that Jesus was his choice.

(If I remember correctly, there were 3 popes at one time back when power was being juggled.)
