…He reveals Himself as Person: or reveals that in Him which is Person. For – dare one say it? In a book it would need pages of qualification and insurance – God is in some measure to a man as that man is to God. The door in God that opens is the door he knocks at. (At least, I think so, usually.) The Person in Him – He is more than a person – meets those who can welcome or at least face it. He speaks as “I” when we truly call him “Thou.”….
This talk of “meeting” is, no doubt, anthropomorphic; as if God and I could be face to face, like two fellow-creatures, when in reality He is above me and within me and below me and all about me. That is why it must be balanced by all manner of metaphysical and theological abstractions. But never, here or anywhere else, let us think that while anthropomorphic images are a concession to our weakness, the abstractions are the literal truth. Both are equally concessions; each singly misleading, and the two together mutually corrective. Unless you sit to it very tightly, continually murmuring “Not thus, not thus, neither is this Thou.” The abstraction is fatal. It will make the life of lives inanimate and the love of loves impersonal. The naïf image is mischievous chiefly in so far as it holds unbelievers back from conversion. It does believers, even at its crudest, no harm. What soul ever perished for believing that God the Father really has a beard?
