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).

In a sense these are questions that most people ask themselves to some extent. They become philosophical when asked with a persistence and rigour that pushes past conventional or evasive answers. It's nothing to do with acquiring a technical facility in an academic discipline.

I'm not sure how far Derrida's later 'theological' interests are really rooted in post-structuralism or whether they don't rather reflect a kind of Kantian-Marxist trajectory - with a French twist on the centrality of liberty, equality and fraternity (cf. Politics of Friendship). Not to mention the role of Levinas and, behind Levinas, Judaism's twinning of eschatology and the call for justice.

Perhaps unsurprisingly, there's a paradox here! Kierkegaard's own indirect communication proposes that we start with the experience of those who don't believe and meet them on their own ground. His success in doing this is evidenced by the fact that, at least for some periods of the 20th century, aspects of his work became a major focus for radical thinkers of various kinds, including the non-religious and, interestingly, a significant number of Jewish thinkers (Buber, Rosenzweig, Taubes, and others).

I'm not sure if Cupitt himself still uses this term, but it's useful in suggesting that, actually, there are more choices than the choice between nihilism and faith. In fact, the issue may not be faith as such but the fact that for millennia, Christianity has buttressed itself with a particular kind of metaphysics that has now seemingly reached the end of its life-span. But perhaps Buddhist metaphysics could provide an alternative here - or, at least, offer a direction of travel.

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.

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.
