The resurrection of Jesus is the pivotal teaching of the Christian faith.
If Jesus had not been resurrected, he would have been just another failed Messiah. Christianity would have been no different from other false religions and cults who venerate their dead prophets.
As such, the resurrection is one of the most attacked doctrines in the Christian faith.
And so some of the attacks on Jesus’ resurrection by atheists, heretics or false religions include:
(1) Attack on the historicity of Jesus
(2) Stolen body theory
(3) Wrong tomb theory
