"Buddhists cannot accept that there is anything either in this world or any other world that is eternal or unchangeable."
Mike: Hi Glenn. It looks like you are posting self-referential humor again! You are saying
that you believe nothing will change a Buddhist's belief that nothing is unchangeable.
Ha ha ha. That's very funny! By the way, if you are defining "Soul" as necessarily eternal or unchangeable, then it appears you are saying the Soul, if it existed, could never learn anything from experience, and thus be changed by it.
Albert Einstein's friend Gustav Stroemberg wrote a book called The Soul of the Universe. Will even the universe itself learn nothing if it has a soul, according to Buddha?
How you define "Soul" and "Eternal" may yet have a few things to teach you. There's no need to come to conclusions yet with billions of (Earth-time) years ahead. Lets not let our clues about Christ or Jesus or Atman or Buddha or Glenn's Self or Eternal Soul come from this world's opinions. (They're so often wrong though that does not mean the opposite of their views is correct. If it were, they'd be doing a great service by explaining their poorly assembled opinions.) Remember the conventional views about religion are rendered useless in practice by the savagery and incoherent thinking of current inhabitants of our Millenia. Religious taboos are merely currency in a pyramid of blackmail and social bullying which under the common cirumstance favors the wrong answers which were hastily arrived at by the middle of the bell curve in intelligence distribution. The best we can often hope for is a truly loving and patient community in our time -- which keeps hope alive for better answers about the questions you raise.
I find that while Buddha & many 'Christians' may disbelieve, Soul IS. Either view may be safely held where speech are religious freedom are truly protected.
