The stories say the miracles are literally true. If we believe them or not is a different matter.And what is it that they were meant to mean?
What many liberal theologians believe about Jesus' death
Many liberal and some mainline Christian leaders believe that Jesus died during the crucifixion, did not resurrect himself, and was not bodily resurrected by God. At his death, his mind ceased to function and his body started the decomposition process. Returning to life a day and a half later would have been quite impossible. The story of having been wrapped in linen and anointed with myrrh seems to have been copied from the story of the death of Osiris -- the Egyptian God of the earth, vegetation and grain. The legend that he visited the underworld between his death and resurrection was simply copied from common Pagan themes of surrounding cultures. One example again was Osiris. "With his original association to agriculture, his death and resurrection were seen as symbolic of the annual death and re-growth of the crops and the yearly flooding of the Nile." 1
They also believe that Paul regarded the resurrection to be an act of God in which Jesus was a passive recipient of God's power. Paul did not mention the empty tomb, the visit by a woman or women, the stone, the angel/angels/man/men at the tomb, and reunion of Jesus with his followers in his resuscitated body. Rather, he believed that Jesus was taken up into heaven in a spirit body. It was only later, from about 70 to 110 CE when the four canonic Gospels were written, that the Christians believed that Jesus rose from the grave in his original body, and by his own power.
Later, perhaps after Paul's death, there was great disappointment within the Christian communities because Jesus had not returned as expected. They diverted their focus of attention away from Jesus' second coming. They studied his life and death more intensely. Legends without a historical basis were created by the early church; these included the empty tomb and described Jesus returning in his original body to eat and talk with his followers.
In previous centuries, almost all Christians believed in miracles as described in the Hebrew Scriptures (Old Testament). These included creation, the story of Adam and Eve, a talking serpent, the great flood of Noah, the drying up of the Red/Reed sea, a prophet riding on a talking ***, the sun stopping in the sky, etc. From the Christian Scriptures (New Testament), they believed in the virgin birth, the Christmas star, angels appearing to the shepherds, Jesus healing the sick, etc. Many, perhaps most, liberal Christians now believe that these stories are not to be interpreted literally as real events. Their faith has not been damaged by losing faith in the reality of these events. A growing number of liberals are now taking the final step by interpreting the stories of Jesus' resurrection and his appearances to his followers and to Paul as other than real events.
