Introduction to Christianity - pg. 92

Here too is the angle from which it would seem to become cler what it means when John presents the Lord Jesus Christ as the real, living name of God. In him is fulfilled what a mere name could never in the end fulfill. In him the meaning of the discussion of the name of God has reached its goal, and so too has that which was always meant and intended by the idea of the name of God. In him - this is what the evangelist means by this idea - God has really become he who can be invoked. In him God has entered for ever into co-existence with us. The name is no longer just a word at which we clutch, it is now flesh of our flesh, bone of our bone. God is one of us. Thus what had been meant since the episode of the burning bush by the idea of the name is really fulfilled in him who as God is man, and as man is God, God has become one of us and so the truly nameable, standing in co-existence with us.
