IN Science and Health by Mrs. Eddy the definition of "Church" is given on page 583 as:
"The structure of Truth and Love; whatever rests upon and proceeds from divine Principle.
"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."
