The Cornerstone Baptist Church was organized when 23 persons joined together in 1874.  As the church met needs in the neighborhood, growth was strong, and in March of 1909 the congregation welcomed its 496th member.

The original Gothic/Queen Anne structure was replaced by the current building in 1968.  The new building housed a sanctuary and education wing, and congregational growth led to the addition of the Starkweather wing with five new Sunday School rooms in 1982.  The sanctuary boasts one of the finest pipe organs in eastern Connecticut.

The church maintains an affiliation with and supports the mission of the Northeast Association and the American Baptist Churches of Connecticut and the USA.  

We are also involved in the ministries of the Killingly-Brooklyn Council of Churches, and with local community missions.
