I would simply observe that the issues may be deeper than Greg suggests. I've long been convinced (and taught) that underneath the desire to meditate between scientific naturalism and theological orthodoxy is the fundamental epistemological dualism of the Kantian worldview. That is to say, the division between phenomena and noumena which has led to a distinction between knowledge and understanding, between scientific method and sentimental intuition.
That's why as long as evangelicalism emphasizes Christianity as simply a religion of the heart without any reference to the orthodoxy of the mind, she will always struggle with liberalism. And that's because anti-intellectual pietism buys into this Kantian/modernist epistemology that separates mind from heart, knowledge from intuition, science from religion, phenomena from noumena.
At its best, Christianity has emphasized knowledge, affections, and volition together; piety and learning united. Until we debunk the modernist epistemological presumptions that underlie theological liberalism (and much of conservative evangelicalism) we will continue to wrestle and fight against her.
