God then
is infinite and incomprehensible, and all that is comprehensible about Him is
His infinity and incomprehensibility. But all that we can affirm concerning God
does not shew forth God’s nature, but only the qualities of His nature. For
when you speak of Him as good and just and wise, and so forth, you do not tell
God’s nature but only the qualities of His nature. Further there are some
affirmations which we make concerning God which have the force of absolute
negation: for example, when we use the term darkness, in reference to God, we
do not mean darkness itself, but that He is not light but above light: and when
we speak of Him as light, we mean that He is not darkness. (An Exact Exposition
