Christ Jesus was unique. He was uniquely dedicated to the things of Spirit. He outgrew physical and personal views of himself. His love of divine law, his understanding of it, and his faithfulness to it brought about his resurrection and ultimately took him beyond the ken of the senses. "As the reward for his faithfulness, he would disappear to material sense in that change which has since been called the ascension," Science and Health, p. 34 Mrs. Eddy explains in Science and Health.
The spiritual brilliance of Jesus' life and demonstrations may seem almost beyond our comprehension. And his ascension may seem to have little relevance for us. But all spiritual concepts have timeless meaning. They are equally significant on one day as on any other, equally significant in any millennium. They apply universally. And Jesus' experience points to possibilities for us. He was our Way-shower.
Ascension, then, can have realistic meaning for us in down-to-earth life today. That's not to trivialize ascension but to appreciate what it's about, scientifically. Ascension, as seen in Christian Science, is not a theological abstraction, nor only a one-time event from nearly two thousand years ago. It's something that relates to each of us in the present century.
