I've just been listening on YouTube an interview of Fr. Robert Rohr on the Cosmic Christ. And a new slant on an idea, to me anyway, was expressed.
On the first day the Light described in Genesis was the Cosmic Christ. So many places in the New Testament mention the Christ being from the beginning.
Just as I've often said (as did Rohr), Christ is not the last name of Jesus. Jesus became the anointed one, the Christ. He was able to shine the Christ though his physical vehicle with no distortion. People met God in him.
From the Desert Fathers, Hildegard of Bingen, Meister Eckhart, Jacob Boehme, Thomas Acquinas to Teilhard de Chardin and more recently Matthew Fox and Richard Rohr - the Cosmic Christ has been discussed and it was known that it has been always. The first body of Christ is creation. As Celtic Christianity speaks, we read God in scripture and in creation.
If we settle for a smaller understanding, we miss the inner message and the direct experience that Paul spoke of, The Christ in you, the hope of glory.
