The Christian Science Quarterly (Bible Lessons) is a publication of the Christian Science Publishing Society that sets out the Bible lessons for all students of Christian Science. Each lesson serves as the Sunday sermon in church and is studied for the week preceding the Sunday on which it is read as the sermon. Daily Bible study and Sunday sermon Called the Lesson-Sermon, each week's Bible lesson is read in daily individual study during the week, and as the Sunday sermon in Christian Science church services around the world. It is composed of a series of references from the Bible and the Christian Science textbook, Science and Health with Key to the Scriptures, written by Mary Baker Eddy. The particular topic for each week's lesson follows one of twenty-six subjects chosen by Eddy, who "discovered" Christian Science in 1866 and founded the church in 1879. The citations for each lesson are selected by the Bible Lesson Committee in Boston, Massachusetts. The subjects are (in order): God; Sacrament; Life; Truth; Love; Spirit; Soul; Mind; Christ Jesus; Man; Substance; Matter; Reality; Unreality; Are Sin, Disease and Death Real?; Doctrine of Atonement; Probation After Death; Everlasting Punishment; Adam and Fallen Man; Mortals and Immortals; Soul and Body; Ancient and Modern Necromancy, alias Mesmerism and Hypnotism, Denounced; God the Only Cause and Creator; God the Preserver of Man; Is the Universe, Including Man, Evolved by Atomic Force?; and Christian Science. The sequence of 26 subjects is studied twice each year, though the passages change from week to week, making each week's lesson different. There is no special Christmas or Easter lesson, however there is an additional lesson for Thanksgiving, read in the United States on Thanksgiving Day. For countries other than the U.S., the Thanksgiving service is optional. When there are 53 Sundays in a year, the subject Christ Jesus is added a second time. The lesson begins with the "Golden Text", a short passage from the Bible related to that week's subject. It is followed by the "Responsive Reading", Bible verses which expound on the focus set by the Golden Text. During the Sunday service, the reading of these verses alternates between the lay First Reader and the congregation. The body of the lesson is divided into several sections, which further develop different aspects of the subject. Bible verses are read first in each section, followed by passages from Science and Health which correlate
