Truth has always been present, but the promise of the Comforter is the promise of the coming of a deeper and more widespread understanding of Truth than was earlier received. This new effulgence of eternal light comes as the result of the continual activity of the Christ in transforming human thought. The line of spiritual unfoldment reaches across the boundaries of time and unites everyone in the embrace of Christianity and Christian Science. Mrs. Eddy writes, "Christ's Christianity is the chain of scientific being reappearing in all ages, maintaining its obvious correspondence with the Scriptures and uniting all periods in the design of God." Science and Health, p. 271;
The Church of Christ, Scientist, and the Cause of Christian Science are outward evidence of the spiritual activity of the Christ and its Science. This Science has come in accordance with biblical prophecy. In the Old Testament, spiritual discernment repeatedly testified to the coming of the Messiah. These prophecies were fulfilled in the life and practice of Christ Jesus. He lived the power of Truth. He taught and demonstrated the Christ. Always aligning himself with his Father, divine Love, he showed mankind the way to healing and eternal life. But Jesus indicated that there was to be a further flowering of the truth when mankind would more readily receive it. Speaking to his disciples, he said of the Comforter, or "Spirit of truth": "I have yet many things to say unto you, but ye cannot bear them now. Howbeit when he, the Spirit of truth, is come, he will guide you into all truth." John 16:12, 13;
Jesus did not limit his concept of Church to a group of people and a physical structure. He consistently turned away from the material sense of things to the spiritual reality, the divine idea. Even the institution we call church can never be confined to a material form, for it is the evidence of the power of Truth and Love washing away error.
