Ideally one would leave their colored lens at the door when they try to learn, but the fact is that is impossible. You may not have christian colored glasses but you have colored glasses (read Thomas Kuhn) and I doubt you would make it through the Middle Age of the Great Books very smoothly with those anti-christian views.
And as a Graduate of Gutenberg I can with confidence say that despite most students and all the Tutors being christian, they do a really good job of leaving Christianity out of most of the discussions.  The first goal for them when reading a book is to understand what the author is trying to say, using the book we are reading and the context of when and where in history it was written. We know Christianity was not on the table for Aristotle, so why would we discuss Christianity when we are reading The Nicomachean Ethics by Aristotle? 
And not all Christians throw Darwin out just because it doesn't line up with what they think the Bible says.
