I think the problem with Christianity and the Christian world view is that they see their God as objective structure, the source of meaning, and complete truth.
But really, there is no objective meaning or truth. Try to think of a single word that can be defined without the need for other words. You can't. Try to explain colors to someone who is blind, you can't. for you colors exist and are tangible... for the blind person they don't. Structure and order depends on structures that precede it and follow it. "Genesis" (both capital G and lowercase g) does not happen from nothing. Even the chaos or nihilism that existed before Genesis had a structure, even if it was inverse to what actually happened in the Christian Genesis. The works of philosopher Jaques Derrida go into great detail on post-structuralism and deconstruction.
As far as truth goes, there is no "truth" either, only the power of discourse. Back to our metaphor on describing the concept of "color" to a blind person... even first-person experience in the senses is not objective and universal truth.
Look at what we know about science and what we have accepted as "truth" in the past... the Earth centered universe, the Earth being flat, Galenic medicine (the humors)... all that stuff has been discredited now. If the LHC doesn't vaporize us first, it may turn everything we currently accept as "truth" about the universe on it's head. The meaning of "truth" changes in reflection to the norms that exist during any time period. What becomes knowledge does not become knowledge based on any objective "truth," rather it becomes knowledge via those who have the power to establish "truth" through discourse (doctors, scientists, etc etc). Recommended reading here is Michel Foucault's Dicipline and Punish and The Archaeology of Knowledge.
Really, the main function and purpose of religion is to establish and enforce a system of social norms. But where religion gets it wrong is to say that there is an absolute structure and an absolute and objective truth. The nature of "reality" as we experience it is change, transcendence, the variables that exist between sign and signified.
There is no structure but what we create for ourselves.
