Gerd Ludemann asks the question and gives his answer in this article.
Jim West then gives his answer here.
This is an issue I've thought about quite a bit. Unfortunately, I don't have a dynamic response to the question. My answer, though, is yes. Here's the comment I left on Herr West's site:
I’m certainly in agreement. Theology cannot be done properly outside of faith (I’m going to get in trouble for that). However, the Venerable John Henry Newman makes the analogy of a blind man. “To speak to a blind man of light and colours, in terms proper to those phenomena, would be to mock him; we must use other media of information accommodated to his circumstances…” Likewise, when the mind is not submitted to the mysteries of God, the theology will be lacking. This is yet *another* dreadful consequence of the “Enlightenment” where the seminary was replaced by the university.
What say ye?
