How is praying understood within the "Death of God" theology?

Theologians like Hamilton and Altizer defend a "secular Theology" that tries to banish the *Deus ex machina* of traditional Theism. So far so good, but how does one pray before God *etsi Deus non daretur*, (to use Bonhoeffer's expression)? How does one interpret things like, for instance, the Ignatian "consolation" felt sometimes in prayer without appealing to any "religious" agency? More specifically: is it possible to elabore a spiritual theology without appealing to religious categories or traditional Theism?
