Old South Church in Boston, otherwise known as New Old South Church or Third Church a meeting house, or mouth-house of the United Church of Christ (historically related to the Congregationalists). It is home to one of the older religious communities in the United States, organized by dissenters from Boston’s First Church in 1669, and from that time known as the Third Church in Boston. The Third Church’s congregation met first in their Cedar Meeting House (1670), then at the Old South Meeting House (1729) at the corner of Washington and Milk Streets in Boston. Members of the congregation have included Samuel Adams, William Dawes, Benjamin Franklin, Samuel Sewall, and Phillis Wheatley. In 1773, Samuel Adams gave the signals from the Old South Meeting House for the “war whoops” that started the Boston Tea Party.

During the Unitarian Movement of the early 19th century, Old South was the sole Congregational Church in Boston to adhere to the doctrine of Trinitarianism. In 1816 Old South Church joined with Park Street Church to form the City Mission Society, a social justice society to serve Boston’s urban poor. During the American Civil War, Old South became a recruiting center for the Union Army under minister Jacob Manning. Though the congregation was not entirely abolitionist, it strongly supported the Union cause. The conclusion of the Civil War was followed by an expansive time of increased inclusion for the congregation. Under minister George Angier Gordon the congregation moved from its meeting house at Washington Street to its Back Bay location in 1875, occupying the present church constructed on newly filled land.

Old South’s commitment to urban ministry and care continued on into the 20th century becoming a segue for the inclusion of new members increasingly diverse by race, class, and sexual orientation. The congregation supports the God is still speaking initiative of the United Church of Christ, and has formally adopted a platform of equality, social justice, and peace.
