What it does remind us is that 'God' is not to be separated from the quest for the Kingdom of God and is not and cannot be the object of any detached 'scientific' contemplation. Heidegger's critique of onto-theology is also driving a wedge between speaking of God and the aims of science - not so as to get rid of God but rather to free God from a false objectification.

Schleiermacher, however, starts by attempting to find what he takes to be a basic element of the human condition as such, namely, that we did not invent ourselves but find ourselves born into a life and a world that precedes us in manifold ways.

Religious life is about something real in human experience that is not constrained by what Wittgenstein called 'all that is the case'. In this sense Heidegger is not simply 'mistaken' - he just asks us, as philosophers mostly do, to think more carefully about what we're saying.

Positively, he [Heidegger] shows that the prospect of death doesn't of itself destroy all possibilities of meaning but calls instead for these to be relocated from fantasies about a future post-mortem life. However, I don't think he does enough in this work to show that this relocation has - I believe - a primarily ethical character (in Levinas's sense of 'ethical').

And perhaps this has to do with what I sense is a turning away from the idea of religion as being about conserving a certain heritage from the past towards religion as having to do with how we orientate ourselves to the future, to all we truly long for, to hope.

Every stroke a tennis player plays is different, yet we perceive them as playing in a distinctive and unique way. It's what Heidegger called a certain 'how' of existing. It's ultimately always singular, and the double task of (a) getting it in view and (b) communicating it to others will inevitably be marked more often by failure than success!
