In 1895, Mary Baker Eddy took a significant step to safeguard the purity of the revelation of Christian Science. She announced: "Humbly, and, as I believe, divinely directed, I hereby ordain the Bible, and 'Science and Health with Key to the Scriptures,' to be hereafter the only pastor of The Church of Christ, Scientist, throughout our land and in other lands.
"From this date the Sunday services of our denomination shall be conducted by Readers in lieu of pastors." Miscellaneous Writings, pp. 313-314;
Mrs. Eddy established this ordination of the Bible and the Christian Science textbook by a By-Law in the Manual of The Mother Church.See Man., Art. XIV, Sect. 1;
