Why did the Jews lie about Jesus?

[fredd bear]

To give a brief summary, the earliest traditions of Jesus do not allude to a bodily resurrection; the latter traditions are embellishments.

 Sounds about right.  I only recently learned that the term "Christian" only came into mainstream use after it was adopted by the emperor Theodosius, in the fourth century.. 

Christians  started squabbling amongst themselves and scrabbling for power almost from the very start, and have never completely stopped. Harder these days because they are no longer allowed to burn 'heretics' alive.

 A bit OT: A fascinating study in itself is the morphing of  Mayan/Aztec/Inca gods into  the Marian cult (for goddesses)  and  a range of Christian saints (gods) As I said, the Church has always been flexible, as long as it's been the church doing the flexing.
