While the Sadducees denied the Doctrine of the "resurrection" altogether (Luke 20:27), the Pharisees interpreted the Doctrine of the "resurrection" as the raising of a dead physical body from the grave. This was the fundamental conflict between Jesus and the Pharisees.
In contradiction of the Teaching of Jesus on the Doctrine of "resurrection", then, Paul, the Pharisee, introduced the doctrine of the physical raising of a dead body into Christian theology; an error which, subsequently, was expropriated by the Muslim theologians in contradiction of the Revelation of the "resurrection" received by Mohammed and conveyed in the Koran.
