In the Christian Science textbook, page 349 of the textbook she states: "The chief difficulty in conveying the teachings of divine Science accurately to human thought lies in this, that like all other languages, English is inadequate to the expression of spiritual conceptions and propositions, because one is obliged to use material terms in dealing with spiritual ideas." (See also her books No and Yes 11:8—11 and Miscellaneous Writings 365:26-27.)
The two Concordances to Mrs. Eddy's writings list several references to passages where she speaks of different phases of error as being the opposites of God; but she also indicates, in varying terminology, that God, infinite Mind, Spirit, Soul, Principle, Life, Truth, Love, has no opposites. In some instances she found it necessary to explain her teaching of Christian Science with material, or relative, terms, while in others she employed spiritual, or absolute, statements of truth.
In discussions of Christian Science we sometimes hear it said, for example, that some form of error is "outside God's allness." or that it is "the opposite of Truth." Both of these expressions are relative statements and are not intended to imply that error is located over here and Truth over there, or that Truth occupies space here and error occupies space somewhere outside of Truth. If in our endeavors to forsake error and to demonstrate the allness of God, good, we declare error to be the "opposite of Truth" or "outside God's allness," we must be very sure that by so declaring we are not in our thought giving error location, space, reality, or power.
