Organized in 1926 as a branch of The Mother Church in Boston, First Church of Christ, Scientist has maintained a Christian Science worship presence in La Mesa for nearly a century. A 1996 Pasi pipe organ replaced the original 1959 Estey instrument and anchors both worship services and a free community concert series, adding a performing-arts dimension to La Mesa Village's cultural calendar alongside The Lamplighters Community Theatre. Christian Science arrived in La Mesa in 1915 when a small group met above a jewelry store near 8250 La Mesa Boulevard, eleven years before the branch church formally chartered. The congregation currently gathers at its Reading Room at 8370 La Mesa Boulevard after selling its original sanctuary, maintaining both a Sunday worship service and a midweek testimony meeting in the Village storefront. Seasonal observances including Thanksgiving and Easter require floral arrangements, communion preparation, and special music programming through the Pasi organ, with sanctuary florals coordinated through La Mesa Village providers including Allen's Flowers & Plants. The Pasi pipe organ installation required custom architectural coordination to optimize wind-chest placement, tonal projection, and voicing within the auditorium's acoustic envelope—a capital project that transformed the space into a recital-grade venue for both worship and public concert programming.
