With the Mystery of Golgotha Christ entered earth-life, and He has remained in earth-life since then; and from this point of view we can feel it as good fortune for earth-life that Christ should have entered it. But now let us consider this from the standpoint of the Angels — which is no invention of mine, but follows as a reality from occult investigation — let us transfer ourselves to the standpoint of the Angels. Their experience in the spiritual sphere was quite different, it was the reverse of ours. Christ left the sphere of the Angels to come to mankind; He forsook their world. Speaking for themselves they could say: Christ left our world to go through the Mystery of Golgotha.
And they would have as much reason to sorrow over this as we have to rejoice that Christ in His healing power should have come to us in as far as we live on earth in our physical bodies. This is a real train of thought, and anyone with actual knowledge of the spiritual world knows that there is only one way for the Angels to find solace, and I described it rightly when I said that men on earth in their physical bodies should live with the Christ-thought in such a way that it can shine upwards as a light to the Angels — since the Mystery of Golgotha — shine up to the Angels as a light.
