Through the discovery of Christian Science by Mrs. Eddy the spiritual idea of Church is unfolded. Mrs. Eddy defines the spiritual concept of "Church," as, "The structure of Truth and Love; whatever rests upon and proceeds from divine Principle." Science and Health, p. 583; This spiritual idea of Church reveals all that is needed to free mankind from the thralldom of material living. Its supremacy is invincible, irresistible, imperishable. It corresponds to the kingdom of God in consonance with Christ Jesus' teaching. It was expressed by Christ Jesus in the church established for the pure purpose of inaugurating and maintaining spiritual and healing redemption, and today it is manifested outwardly in the Church of Christ, Scientist.
This Church, The Mother Church, was spiritually conceived and was established through discernment and demonstration of the spiritual idea of Truth and Love by Mrs. Eddy; it cannot be overshadowed by traditional beliefs, opposed by human powers, or subordinated to ecclesiastical laws. The Church of Christ, Scientist, is empowered to be the essential agency in the redemption of mankind.
Mrs. Eddy continues the definition of "Church" as it is evidenced in human experience: "The Church is that institution, which affords proof of its utility and is found elevating the race, rousing the dormant understanding from material beliefs to the apprehension of spiritual ideas and the demonstration of divine Science, thereby casting out devils, or error, and healing the sick."
