Buddhism and Christianity: On Grief, Mandalas, and Resurrection

The early Christians had to deal with the loss of their most important mandala — the one they called their Lord and Savior, Jesus Christ. Isn’t Christianity weird? I mean, Christians revere Jesus the Messiah, the King. That’s weird because the one Christians revere as the incarnate word of God was killed. He became a victim of human violence. 

How do you atone for that? How do you reconcile with the fact that the one whom Christians worship became a victim of human violence?
