""admitting [I] might be wrong in my belief in [my] deity undermining my entire worldview"

Thanks for the reply DmG, interesting stuff. Does admitting you might be wrong in your belief in a deity not mean you have a smidgeon of doubt about the existence of that deity? If it does, how do you address that doubt? Reflection? Scripture?

I'm not sure the analogy with football teams etc is valid though; these are opinions and not beliefs, not the basis for forming a moral code, for example. We accept that other people differ in opinions about football teams and art because we understand these opinions are subjective and however vociferous in our support of our stance, it's only the ignorant who would say theirs was the only correct opinion.

I would class myself as an agnostic, having left religion behind many years ago. I do think about this subject a lot though, but as a scientist I find the scientific method the best way to understand the universe and ourselves, and form a moral framework on the basis of empirical fact. However, science doesn't shelter the homeless or run food banks or give succour to those whom find themselves in distress or suffering; people do that far better and that is why on a local level, churches, mosques and synagogues are vital for our communities.
