Some time ago I had told a commenter that I planned on reading Van Til’s chapter in Introduction to Systematic Theology on the Incomprehensibility of God and blog on it. I never seemed to find the time.
Since my computer was “resting” on Tuesday, I was flipping through my copy of the book. Lo and behold, I have already read that chapter. Silly me. So here I go!
Van Til starts with the problem of knowing the “living and true God, who is infinite in being and perfection, a most pure spirit, invisible, without body, parts, or passions, immutable, immense, eternal, incomprehensible, almighty, most wise…” as our Confession summarizes the Scriptures regarding God. Such a God, according to Kantian epistemology is beyond our experience. In their view, God is not just incomprehensible, but unknowable. The theology of Van Til’s day often embraced such views. God become unknowable, and faith became irrational. It was no longer a faith seeking understanding since there is nothing we can understand about an absolute God.
Aquinas put forth the “way of negation” by which we know God negatively instead of positively. We speak about what God is not rather than what He is. His dependence on Aristotle means he embraces a non-Christian epistemology that descends into a similar irrationalism.
