  There are two remedies for the defects in our knowledge of “what” God is, one taken from faith, the other from reason.  Both make knowledge of God’s existence more like a postulate known with certitude by the “wise” than like an axiom recognized by “all” humans (Boethius, De hebdomadibus, 40).  For Christian belief and for theology, God’s existence is an article of faith. The other remedy is Bonaventure’s adaptation of Anselm’s argument conceived as a philosophical argument on behalf of a metaphysical postulate.
