I see no conflict between philosophy and theology. Theology provides the answers to questions raised by philosophy. Philosophy provides categorizations for understanding and applying theology.
If one spends a few years studying philosophy, they will discover that without revelation, the epistemological search for the answer to the question, "How do we know anything?" ultimately ends in skepticism or nihilism.
Unfortunately, during the age of the Enlightenment faith was relegated to religion and reason to science creating an epistemological divide (as if faith and reason are two different spheres of knowledge) that has yet to be bridged. Progress is being made and we see hints that science without faith is a handicapped endeavor.
Yet, it is the church that has often, and erroneously I believe, claimed to possess truths that are beyond any truth-testing criteria, thereby elevating itself beyond reasoned criticism. Instead of the church being the "pillar and ground of truth", what followed, in my opinion, is the anti-intellectualism of the evangelical movement. Men like Jonathan Edwards have been ignored in favor of appeal to popular culture. One need only look to the open theism movement to see this appeal at work. The church today needs to revisit I Timothy 3:14-15; 1 Timothy 4:12-16; 2 Timothy 2:15; 2 Timothy 3:15-17; and 2 Timothy 4:1-6, where we find the mind is also in need of training and discipline.
The Reformers understood that Christianity was superior epistemologically, for they demonstrated that only Christianity offers a unified view of knowledge. The Reformers did not fear philosophy, but instead used its very tools to proclaim the fundamental truths of reality. The current evangelical movement has taken Colossians 2:8 and made it a shibboleth against anyone who would dare to think deeply and even draw upon philosophy to support Christian doctrines. This is surprising given that the passage is eschewing worldly philosophies (systems) and not the discipline of philosophy. Paul was not simply quoting Scripture when he spent every week reasoning in the synagogue in Corinth (Acts 18:4). Paul's theology employed reason in the process, but not as a source of truth, of understanding Truth.
The use of rational argumentation is not a foreign concept in the Bible--see the use of apologia in Acts 19:33; Acts 22:1; Acts 24:10; Acts 25:8; Acts 25:16; Acts 26:1-2; 2 Timothy 4:16; Philippians 1:7; 1 Peter 3:15. It is from revelation that God, and thus Truth, is known. It is from reason that God, and Truth, becomes knowable.
