With attendance at Sunday services dwindling, mainline Christian churches in New London are merging or moving out of town completely. Newer evangelical churches are filling the void, in some cases by moving into their older buildings, and attracting a younger population. Engaging Heaven Church and First Congregational Church are sharing worship space, with Engaging Heaven having agreed to purchase the building. In the basement of the former Montauk Avenue Baptist Church, Calvary Chapel holds a service called Sunday Night Vibe that draws a younger crowd.
