Emmanuel Episcopal Church, a historic church at 15 Newbury Street in Boston, Massachusetts, was founded in 1860 as part of the Episcopal Diocese of Massachusetts. Designed by architect Alexander Rice Esty and constructed in 1861, it was the first building completed on Newbury Street in Boston’s newly filled Back Bay. In 1899, Frederic Crowninshield designed its sanctuary's centerpiece window, in which the allegorical figure Piety, from John Bunyan's The Pilgrim's Progress, points the way to Emmanuel's Land.
The Leslie Lindsey Memorial Chapel, consecrated in 1924, is considered one of the architectural gems of Boston. An all-encompassing product of and testimony to the artistry of Ninian Comper, the work comprises a decorative scheme for the chapel designed by the architectural firm of Allen & Collens. Comper designed its altar, altar screen, pulpit, lectern, dozens of statues, all its furnishings and appointments, and most notably the stained glass windows. The finest Gothic-revival style craftsmen were engaged for the project under the direction of Campbell & Aldrich of Boston. The chapel memorializes Leslie Lindsey and her husband of ten days Stewart Mason, who were married at Emmanuel Church and perished when the Lusitania was torpedoed in 1915.
Its outreach program in the early twentieth century, known as the Emmanuel Movement, was influential in the development of self-help groups for mental health, particularly for alcoholism. The church is known for hosting Emmanuel Music, which performs Bach Cantatas in their intended liturgical setting, coordinated with the Lectionary.
It currently has a cooperative, interfaith partnership with the Jewish community Central Reform Temple. The clergy from the two congregations regularly offer sermons for each other's congregations, and members are invited to attend the other congregation's services.
