In an influential book of thirty years ago, The Rise of the Social Gospel in American Protestantism, 1865–1915, Charles Howard Hopkins interpreted the founding in 1908 of the Federal Council of the Churches of Christ in America, the forerunner of the present National Council, as a stage in the flowering of the social gospel in American Christianity. His interpretation was soon confirmed by John Alexander Hutchison. In We Are Not Divided, a study of the pronouncements of the Federal Council, Hutchison wrote that the Federal Council was born of the marriage between “the idea of social service and the idea of interdenominational cooperation”. By “the idea of interdenominational cooperation”, however, Hutchison meant little more than what Hopkins had already defined as the impulse for social Christianity, and there the matter has rested for subsequent historians, including two former secretaries of the Federal Council.
