Richard Carrier who in his book ‘The Empty Tomb’ argues that "the earliest Christians probably believed Jesus had received a new body in the resurrection, and that stories of his old body disappearing from its tomb were developed later." He also argues it is less likely but still possible the original body of Jesus was misplaced or stolen.
There are others such as reported atheist Robert Price who is the Chair Of Theological Studies at Johnnie Coleman Theological Seminary, and Fellow of the Jesus Seminar. Has also, in books, such as ‘The Incredible Shrinking Son of Man’, ‘Deconstructing Jesus’ and ‘Beyond Born Again: On Putting Away Childish Things,’ has consistently challenged Biblical literalism and has argued for a more skeptical and humanistic approach to Christianity. He has also helped popularize the Gnostic tradition and has questioned the idea of a historical Jesus. Among atheists and agnostics his books and publications are very popular.
There continues to be a growing list of other atheists, agnostics, skeptics, and so called free-thinkers, promoting a continued rise in ant-Christ and anti-Biblical sentiments.
Then finally there are the near religiously insane such as Fr. John Dominic Crossan Co- founder of the Jesus Seminar who maintains the Gospels were never intended to be taken literally by their authors and the Body of Jesus was probably eaten by dogs ('Search For Jesus' ABC June 26th 2000) and possibly even drug through the streets.
