Another great post, Graham. I so appreciate the depth of your study on these issues. As a self-descrebed "orthodox" Christian believer, the concept of reincarnation is a challenge to my understanding of biblical doctrine. However, after reading Irreducible Mind and the studies of Ian Stevenson and others, I believe this is a concept that Christianity must reconsider. I was not aware of Origen's view on this so this is helpful. I know that Origen ran into trouble with the religious authorities for some of this teaching and I need to look at that more, not sure if these ideas were part of that. Thanks again for your thoughts on these topics.
