What's your opinion on Liberal Religion?

[Alan V]

But again, if it does turn out that mind is always and only dependent on the existence of a physical brain, I am skeptical that this would bring any significant change to Christianity.

I agree with you here. If anything, the dependence of mind upon material reality makes Christianity more poignant.

If minds are always dependent on living, functioning brains, then human immortality and God are impossible. I think that might have an impact on a few people who presently believe in such fantasy constructs, as it did me.

Denial isn't an argument.
