First Church in Boston is a Unitarian Universalist Church (originally Congregational Church) founded in 1630 by John Winthrop's original Puritan settlement in Boston, Massachusetts. The current building is on 66 Marlborough Street in Boston. The church has long been associated with Harvard University.
The church was created in 1630 when the settlers on the Arbella arrived in what is now Charlestown, Massachusetts.John Wilson was the first minister, and the only minister while the church was in Charlestown. Two years later they constructed a meeting house across the Charles River near what is now State Street in Boston, and Wilson was officially installed as minister there. In 1633 John Cotton arrived from England, and was a teaching elder at the church, helping to establish the foundation of the Congregationalist Church, the official state church of Massachusetts. In the 18th century, Charles Chauncy was a minister at First Church for sixty years and gained a reputation for opposing what he believed was emotionalism during the Great Awakening of Jonathan Edwards.
A schism developed at the turn of the 19th century, the trinitarian Christian church eventually transformed into a unitarian congregation by the mid-19th century along with many of the other state churches in Massachusetts. Massachusetts' state churches (largely Unitarian and Congregationalist) including First Church were officially disaffiliated with the government in 1833.
