An adjoining educational building was added in 1956-1957. The facility continues to operate as a nondenominational Protestant church under lay leadership, employing ministers with backgrounds in mainstream Protestant denominations. Since 2007 it has been affiliated with the Center for Progressive Christianity. The church's motto is "Where People from All Denominations Meet in Their Differences, but Are One in Their Search for God."
