Christian Science reveals spiritual concepts, defines them accurately, and demonstrates them scientifically. One such concept is Christ. Throughout the ages this great word "Christ" has meant many things to many people; and it does today. Christian Science, the Science of Christ, expands one's understanding of Christ, explains it in various aspects, and helps one achieve a workable knowledge of its power.
The Christ is timeless. To human sense it seems to come and go; but this only indicates periods of spiritual enlightenment and material obscuration on the part of mankind. Mary Baker Eddy says in "Science and Health with Key to the Scriptures" (p. 333), "Abraham, Jacob, Moses, and the prophets caught glorious glimpses of the Messiah, or Christ, which baptized these seers in the divine nature, the essence of Love."
Christ Jesus lived this essence, the divine nature, in the fullness of its purity and might. He described it as the Comforter, "the Spirit of truth" (John 14:17), and prayed God that this spirit would abide with his followers forever. The spirit of Truth is deeply essential to one's ability to rise above earthliness and manifest the power of God. One recognizes this aspect of Christ in every least expression of good, of justice, tenderness, mercy, forgiveness, truthfulness. In such moments of Christliness the veil of materialism is thrust aside, and the realm of Spirit, entirely apart from the mortal, personal sense of life, is glimpsed.
