No Incorrect Literature.
A member of this Church shall neither buy, sell, nor circulate Christian Science literature which is not correct in its statement of the divine Principle and rules and the demonstration of Christian Science. Also the spirit in which the writer has written his literature shall be definitely considered. His writings must show strict adherence to the Golden Rule, or his literature shall not be adjudged Christian Science. A departure from the spirit or letter of this By-Law involves schisms in our Church and the possible loss, for a time, of Christian Science.
— Mary Baker Eddy, Manual of The Mother Church, Article VIII, Section 11
Mary Baker Eddy regarded her discovery of Christian Science as a revelation from God so essential to the healing and salvation of humanity that she could not shrink from recording it in its native purity for all to understand and practice. She knew from the outset this would not be an easy task; the revelation would meet with resistance because it required that those reading about it make a fundamental shift in their perception of reality.
Even so, every step of the way Mrs. Eddy humbly, reverently, and steadfastly subordinated herself to God, divine Truth and Love, letting Him bring her thought into precise accord with what He was revealing in everything she wrote. Thus, she could say: “The works I have written on Christian Science contain absolute Truth, and my necessity was to tell it; therefore I did this even as a surgeon who wounds to heal. I was a scribe under orders; and who can refrain from transcribing what God indites, and ought not that one to take the cup, drink all of it, and give thanks?” (Miscellaneous Writings 1883–1896, p. 311).
