I have no problem with the concept of the Cosmic Christ, but this essay doesn't do it justice. But the theology is sound and hinted at in the Nicene Creed and even in the New Testament.

" ... And he put all things beneath his feet and gave him as head over all things to the church, which is his body, the fullness of the one who fills all things in every way." (Ephesians 1:22-23)
