I'm reading Warfield on Augustine. I ran across this paragraph and it reminded me of Gordon Clark's view on the Bible being the source of truth. (And his so-called arch-nemesis, Cornelius Van Til, I'm sure would agree).
"Say you are determined to have a religion which you can demonstrate. The very search for it presupposes a precedent faith that there is a God and that he cares for us; for surely no one will seek God, or inquire how we should serve Him, without so much to go on. And where and how will you seek? Who are the wise? How will you determine who are wise in such things? In the manifold disagreements of pretenders to wisdom, it will require a wise man to select the really wise. We are caught in a fatal circle here; we must needs be wise beforehand in order to discriminate wisdom. There is but one outlet; and that outlet is, shortly, revelation."
Vol. IV Works of Benjamin B. Warfield, Baker Book House Reprint (2003), pp. 167-68 (addressing and paraphrasing Augustine "De utilitate credendi")(citations omitted)(emphasis added).
Not a new truth, but one we keep having to relearn: the fear of God is the beginning of wisdom.
