Church! is a nontraditional take on the Christian church, self-described as "a group of people seeking to figure out how to follow Jesus in a challenging and changing world." The congregation gathers on Sunday at the Camp Friendship building on Eighth Street in Park Slope. The church also hosts a number of small group that meet outside of Sunday service to discuss spirituality and interest groups and activities such as triva night, knitting and basketball. Church! also runs the Postmark Cafe coffee shop on Fifth Avenue and Sixth Street.
