Religious conservatives generally view the Bible as inerrant . Thus the resurrection event is not debatable. To them, it actually happened, exactly as described in the Gospels.
Most liberal theologians tend to approach passages in the Bible differently.
They consider it to be written by very human, spiritually minded, fallible authors, who often promoted their own religious belief system. Liberals compare Bible passages in the light of contemporary Jewish, Pagan and non-canonical Christian writings. They also study the culture of the time and the beliefs of surrounding Pagan societies. Of particular interest are the evolving beliefs of the followers of Christ during the approximately 7 decades between the crucifixion and the completion of the last Gospel, John. They have come to very different conclusions about the resurrection.
