Berkhof on the Knowledge of God’s Being

In dealing with our knowledge of the Being of God we must certainly avoid the position of Cousin, rather rare in the history of philosophy, that God even in the depths of His Being is not at all incomprehensible but essentially intelligible; but we must also steer clear of the agnosticism of Hamilton and Mansel, according to which we can have no knowledge whatsoever of the Being of God. We cannot comprehend God, cannot have an absolute and exhaustive knowledge of Him, but we can undoubtedly have a relative or partial knowledge of the Divine Being. It is perfectly true that this knowledge of God is possible only, because He has placed Himself in certain relations to His moral creatures and has revealed Himself to them, and that even this knowledge is humanly conditioned; but it is nevertheless real and true knowledge, and is at least a partial knowledge of the absolute nature of God. There is a difference between an absolute knowledge, and a relative or partial knowledge of an absolute being. It will not do at all to say that man knows only the relations in which God stands to His creatures. It would not even be possible to have a proper conception of these relations without knowing something of something of both God and man. To say that we can know nothing of the Being of God, but can know only relations, is equivalent to saying that we cannot know Him at all and cannot make Him the object of our religion.
