The source is from the NCC (National Council of Churches). From its website (http://www.ncccusa.org/about/about_ncc.html)

“the National Council of the Churches of Christ in the USA has been the leading force for ecumenical cooperation among Christians in the United States. The NCC’s member faith groups — from a wide spectrum of Protestant, Anglican, Orthodox, Evangelical, historic African American and Living Peace churches — include 45 million persons in more than 100,000 local congregations in communities across the nation.”

NO Catholics.
