The First Congregational Church of Darien is a member of  the United Church of Christ (UCC),  a distinct and diverse community of Christians that come together as one church organization to join faith and action.  With more than 5,100 churches and 1.1 million members across the U.S., the UCC serves God in the co-creation of a just and sustainable world.   UCC was formed in 1957 when the Evangelical and Reformed Church and the Congregational Christian Churches united to create one larger community of faith with roots in Congregational, Christian, Evangelical, and Reformed denominations.  Learn more about the United Church of Christ and the Southern New England Conference of the United Church of Christ.
