The United Baptist Church, John Clarke Memorial (previously known as the First Baptist Church in Newport, Second Baptist Church in Newport and the Second Baptist Church in America) is a historic Baptist church in Newport, Rhode Island, USA that was founded in 1638-1644. It is one of the two oldest Baptist congregations in the United States and is currently affiliated with the American Baptist Church. The current meeting house of the church was constructed in 1846.
Around 1638 Roger Williams founded the First Baptist Church in America in nearby Providence, after being exiled from Massachusetts in 1636. In 1638 John Clarke, a minister, from Great Britain, started leading worship in nearby Portsmouth, Rhode Island (Newport County) after he and his congregation were exiled from Massachusetts after disagreements with the Puritan leadership.
By 1644 Clarke's group moved to Newport where the current church was founded and the first meeting house was constructed at Green's End within that same year, which was the first church building of any denomination in the colony. The congregation used the building until 1708 when the first meeting house in Newport was constructed on Tanner Street in Newport on the corner of Calendar Avenue, adjacent to the cemetery, which was established on land donated by Clarke. In addition to Clarke, Obadiah Holmes and John Crandall were active in the leadership of the church in the seventeenth century.
In 1656, while Clarke was in England — advocating for the Colony's royal charter and religious liberty — a group of congregants broke off from the church to found the Second Baptist Church in Newport, which followed Six Principle Baptist (Arminian) principles in contrast to Clarke's more Calvinist theology. (Second Baptist would eventually reunite with First Baptist in 1946, hence its present name.)
