The acceptance of a supreme being who is all knowing, all powerful, perfectly rational is the first assent that man makes to the absolute.
Once this assent is made, then one has already comitted himself to belief in the absolute and unsailable truth, for God is absolute and unsailable.
The only way to believe that there is not absolute and unsailable truth would be to deny the very existence of God.
But if we did that, then mathematics would confront us with absolute and unsailable truths such as the Descartes plane, Euclid’s postulates which have no proof, Pythagoras’ theorem, which can only be proven by an absolute axion that is unprovable.
If we deny that mathematics has absolute and unsailable truths, then we deny quantitative thinking. To deny quantitative thinking, would annul rational thought.
Rational thought is the joint venture of the quantitative and the qualitative.
If we deny the existence of rational thought, then we have no way of proving our own existence.
Thus we achieve perfect nihilism and we are back in the world of absolutes, for nihilism is absolute.
