Would like to know how christianity oringinated?.Where we got seperated from Jews?.Christians celebrate Passover day?

Christianity was started by Christ. The Jews didn't believe that He was Christ and crucified Him. Christ came back to life and rose from the dead to show that He was Christ, Then ascended up into heaven and sat down at the right hand of God. Christ is the final passover.

This is really a new information to me that Jews don't beleive Jesus.I hope I have to learn a lot.I wasted most of my time just simplying learning all maths and physics......Now I am spending some time to learn what's happening around.I am happy that you people are there to help me ...thanks for updating me.....
