 Deism, which was largely led by rationality and reason, could allow a belief in the immortality of the soul, but not necessarily in the resurrection of the dead.American deist Ethan Allen demonstrates this thinking in his work, "Reason the Only Oracle of Man" (1784) where he argues in the preface that nearly every philosophical problem is beyond humanity's understanding, including the miracles of Christianity, although he does allow for the immortality of an immaterial soul.In Christian theology, it was once widely believed that to rise on Judgment Day the body had to be whole and preferably buried with the feet to the east so that the person would rise facing God.
