It is sometimes said that Christian Science is mind over matter. And it is sometimes said that it is not. If we capitalize Mind, it is. If we do not, it is not.
God, the divine Mind, governs all. A realization of this gives one the ability to apply practically the governing power of Mind in all things. But this practical application necessarily includes the rejection of any mind other than the divine.
The so-called mind of a mortal appears to govern the body in every instance. But a Christian Science healing is a demonstration, in a particular instance, of the powerlessness of mortal mind. The healing takes place in the physical body because what appear to be a mind and a body are not two but one. Mary Baker Eddy writes, "Matter is but the subjective state of mortal mind." The First Church of Christ, Scientist, and Miscellany, p. 109; A diseased condition of the body, therefore, is not diseased matter but a diseased state of mortal mind. When the influence of this so-called mind is rejected, and the fact of the one divine Mind is acknowledged, human consciousness is, to a degree, freed of the illusion of a material body, and the disease disappears.
