Weekly Bible lessons are "a lesson on which the prosperity of Christian Science largely depends." — Mary Baker Eddy

Bible Lessons and Sunday Sermons
Twenty-six Bible Lesson topics are covered twice a year plus a special lesson for Thanksgiving morning. Each week's lesson is divided into sections (usually six) which include subtopical passages from the Holy Bible and correlative passages from Science and Health with Key to the Scriptures by Mary Baker Eddy. Each lesson is prepared by the Bible Lesson Committee in Boston, Massachusettes for that week: (Bible Lessons are studied each day of the week and read at every Christian Science Sunday service worldwide).

"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." (Miscellaneous Writings 1883–1896, Mary Baker Eddy, p. 313:25)
