Jesus is the microcosm; Christ is the macrocosm. There is a movement from Jesus to the Christ that you and I have to imitate and walk, as well. A lot of us have so fallen in love with the historical Jesus that we worship him as such and stop there. We never really followed the same journey which he made, which is the death and resurrection journey. Jesus died and Christ arose.
Unless we make the same movement that Jesus did—from his one single life to his risen and transformed state, we probably don’t really understand what we mean by the Christ—and how we are part of the deal! That is why he said "follow me.” The Jesus that you and I participate in, are graced by, and redeemed by, is the RISEN Jesus whohas become the Christ, which is an inclusive statement about all of us and all of creation.
It's hard to grasp the difference (without de-emphasizing the unity) in character of the Cosmic Christ and Jesus of Nazareth. One is bound by time and space, the other is transcendent and intimately knowable...
Good food for thought. Thanks Fr. Rohr.
