On page 274 of the Christian Science textbook, "Science and Health with Key to the Scriptures," Mary Baker Eddy, its author, writes, "Divine Science is absolute, and permits no half-way position in learning its Principle and rule—establishing it by demonstration." In numerous places in her writings Mrs. Eddy refers to Christian Science as absolute Science, and the teaching of Christian Science lays its emphasis on the oneness and wholeness of Deity—one absolute God.
Mrs. Eddy was especially careful in her choice of words. When she says that Christian Science is absolute, she does not mean that it is transcendental in a philosophic sense. It is in fact quite the contrary. The word absolute is perhaps not always clearly understood. When speaking of the absolute, people have thought of it as something more or less intangible or impractical, but this is not so.
As used in Christian Science, the word absolute conforms to the best dictionary definitions, and therefore when referring to God as absolute we mean that God is entirely perfect, whole, complete, real, actual, immaculately pure, without limit or restriction, free from error or variability. All true knowing, to be real and have its origin in Truth, must be from the basis of absolute, uninterrupted perfection.
