At a theoretical level, I think a naturalist approach to religion is just asking questions I'm not interested in. They're perfectly legitimate in their own terms, but they don't address the actual experience of how one or other aspect of religion becomes existentially meaningful to us in our actual lives. The fact that we ourselves are the subject of investigation makes all the difference.

For others the mourning is over. Others would say that whilst one God has died - the God of ontotheology perhaps? - this allows for the good news of a God who is to come, a God who will be better able to gather up and give justice to all the manifold aspirations of human life towards goodness and meaning (and not just to those who are able to fit into a narrow 'religious' framework).

It seems that just Being, the sheer fact of existence, that there is something rather than nothing, already inspires a wonder akin to religion. But - as in my comment about the Kingdom of God in the last answer - Jewish and Christian traditions are also prepared to challenge what 'is' for the sake of what could be.

I think he [Heidegger] sets the question up in a useful way and, despite appearances, he's not 'against' technology. He just wants us to have a questioning and thoughtful relation to it. This must be relevant to any approach.

However, in brief, I think the connecting of 'God' and 'Being' is one of these things for which there seems to be a natural impulse in human thinking but it can also lead to confusions. Religious believers mostly want to see God as the epitome of what is most really real and in some non-theistic contexts, people talk simply of 'Isness'.

Interpretation is a task that we repeatedly have to take up and start again from the beginning, Sisyphus-like. But, as Camus said, we must always imagine Sisyphus happy, and this is not so difficult when it's a matter of texts that reveal important truths about being human.

In brief, I regard love as a more decisive focus of meaning than death. In terms of Heidegger's argument, this is because I think he misdescribes the importance of the deaths of others and focuses exclusively on my relation to my own death. But, in reality, the deaths of others have a more urgent and immediate impact on our lives than the purely notional knowledge that I too will one day die.
