What beliefs would we consider reasonable for a self proclaimed Christian to hold?

[vulcanlogician]

It doesn't matter because perfectly healthy brains can experience hallucinatory experiences.

And your first article starts with a quote from Heisenberg--it's something that he never said. I kinda stopped there. The podcast is an hour long. Too frikkin' long!

Look, next time your on, put a link to something relatively brief that you think makes a rock solid case for NDEs and I'll look at it. But you may as well not even bother posting an hour-long podcast, man. You can have hour-long podcasts about the moon being a hologram. Nobody wants to sit through an hour of unsubstantiated claims.

I did a google search on the quote. It seems that Helsenberg did actually say that. Here is another site if you are interested:   http://the-formula.org/how-to-deal-with-...-atheists/

I'll get back to you on your link. Meanwhile...
