Now, as at the beginning of the 19th century, there is a certain discovery of Eckhart and related figures. There are questions as to how far our Eckhart accords with the real medieval teacher of that name, but there are certainly images in his work that help us work our way past several of the aporia with which we're confronted in our attempts to think about God.

And this is also what he takes Christian doctrine, in all its complexity, to be centrally about, that is, teaching an attitude rather than a set of propositions. Call it joyous openness to life. What's not relevant about that?

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.

Sartre is one example of someone who does just this. Every text is, after all, a human document and whatever Kierkegaard thought about God was clearly a matter of human thought that can, in principle, be retrieved and interpreted by other human beings. A phenomenological approach to religion must, it seems to me, adopt the old adage: nothing human is alien to me.

I still read a lot about teenage angst! Of course, any kind of mourning CAN become pathological and then it 'has to stop', but to move through life untouched by the loss of hopes, beliefs and aspirations once cherished is also questionable.

Of course, if one's reading Kierkegaard for personal interest that's fine - but it's sloppy scholarship just to cherry pick what suits one from a particular author, whether it's Kierkegaard, Heidegger, or whoever. Nevertheless, it does seem to me that even the more religious parts of the authorship can offer significant insights into the meaning of the human condition to those who can't then say that, e.g., they believe Jesus Christ is the Son of God and their personal Saviour.

But why should a religious person be interested in a work like Heidegger's that many regard as the epitome of nihilism? For a start, because Heidegger forces us in a way that few philosophers do to really think through the seriousness and all-encompassing nature of our mortality.
