A Reader in a Christian Science church is a member of the congregation who has been elected to serve in one of two positions responsible for church services.
 Each week's sermon in Christian Science churches is outlined in the "Christian Science Quarterly", prepared months in advance, and is the same in all Christian Science churches, worldwide.
 A lay church, it has no clergy; rather, the sermons consist of passages from the "Bible" and the Christian Science textbook, are studied as lessons during the week and are read aloud to the congregation on the Sunday following.

First Church of Christ, Scientist Building is an historic Christian Science church located at 1519 East Denny Way / 1841 16th Avenue on the corner of East Denny Way and 16th Avenue in the Capitol Hill neighborhood of Seattle, Washington.
 Designed in the Classical Revival style, it was built of Bedford limestone between 1906 and 1909.
 Established in August 1896, First Church first held services in various rented buildings or halls until building its first church building on the corner of 6th Avenue and Marion Street.
 This was completed in time for its first service on Easter Sunday, April 7, 1901.
 This was soon outgrown and in November 1906 a contract was signed to purchase the Denny Way property.
 In August 1908, services began in a temporary wooden structure that was built on the completed foundation of the new church.
 On January 17, 1977 the building was declared a City of Seattle historic landmark.
 In 2006 the congregation made the decision to move to the South Lake Union neighborhood to be in a more active urban location.
 The building on East Denny Way was sold to a developer who has since converted it into townhouse project called The Sanctuary.
 First Church of Christ, Scientist, Seattle, now holds services at 900 Thomas Street and is still an active branch of the Christian Science Mother Church.
A Christian Science Reading Room is a place operated as a public service by a Christian Science church in the community where that church exists.

Mary Baker Eddy (July 16, 1821 – December 3, 1910) was the founder of Christian Science, a new religious movement in the United States in the latter half of the 19th century.
A Christian Science practitioner is an individual who prays for others according to the teachings of Christian Science.
 Treatment is non-medical, rather it is based on the Bible and the Christian Science textbook, "Science and Health with Key to the Scriptures" (1875) by Mary Baker Eddy (1821–1910), who "discovered" Christian Science in 1866 and founded the Christian Science church in 1879.
 According to the church, Christian Science practitioners address physical conditions, as well as relationship or financial difficulties and any other problem or crisis.
 Practitioners are either "listed" or "unlisted," a designation that refers to a form of international accreditation maintained by The Mother Church, in Boston, Massachusetts.
The Manual of The Mother Church is the book that establishes the structure and governs the Christian Science Church, functioning like a constitution.
 It was written by Mary Baker Eddy, founder of the church.
 It was first published in 1895 and was revised dozens of times.
 The final edition, the 89th, was published in 1910, two weeks after her death.
The Destiny of The Mother Church, by Bliss Knapp is a controversial book published by Christian Science Publishing Society in 1991.
 Knapp and his parents, Ira O. and Flavia Stickney Knapp, all knew Mary Baker Eddy.
 His parents were students of hers and his father was one of the original members of the Board of Directors of The Mother Church.
 Until 1991, the book was repeatedly rejected for publication by the Christian Science Board of Directors because of the depiction of Eddy as the fulfillment of biblical prophecy and equating her with Christ Jesus, a position which Eddy considered blasphemous.
 Eddy identified the woman in the Book of Revelation not as a person, but as "generic man".
 "Destiny's" publication caused divisions within the church, including several resignations of prominent church employees.
 Critics claimed that the failure of the church's then-recent television venture, which had cost the church several hundred million dollars, had motivated the Board's reversal on publishing Knapp's book.
 Knapp, his wife and her sister left wills that granted bequests totalling over $100 million (in 1990s dollars) promised to the church if the book were to be published.
 The wills set a time limit of 20 years for the book to be published, otherwise the bequests were to be divided between Stanford University and the Los Angeles County Museum of Art, and the church would receive nothing.
 The 1973 death of Knapp's wife set the date of the time limit to May 1993.
The Christian Science Hymnal is a collection of hymns sanctioned for use in Christian Science services including Sunday services and Wednesday evening testimony meetings, as well as in occasional informal hymn sings.
 It includes both traditional Christian hymns, traditional hymns with minor adaptations better suiting Christian Science theology, and hymns unique to Christian Science, including seven poems by the denomination's founder Mary Baker Eddy set to various tunes: "Christ, My Refuge", "Christmas Morn", "Communion Hymn", "Feed My Sheep", "Love", "Mother's Evening Prayer", and "Satisfied".
 Found in the Supplement section are the hymns, "I Need Thee Every Hour", "I'm a Pilgrim and I'm a Stranger", and "Eternity", which were originally included in the Hymnal in accordance with [Mrs. Eddy's] wish."
The First Church of Christ, Scientist is the administrative headquarters and mother church of the Church of Christ, Scientist, also known as the Christian Science church.
