Outside of the Episcopal Church, "Crapsey went right back to what he had always done," but without the confines of ecclesiastical authority. Crapsey gave his efforts to his Brotherhood for "social and religious reform." For this work, he added Walter Rauschenbusch, who was "a young and radical minister." Crapsey reorganized what previously had been the brotherhood of Andrew's as the Brotherhood. The Brotherhood served as Crapsey's congregation. He taught Sunday School and "considered himself the pastor of the Brotherhood." Membership in the Brotherhood was open to people of any "race, nationality, class or creed." The Brotherhood's purpose was "to unify the race of mankind in God and in one another." As pastor of the Brotherhood, Crapsey often gave eulogies at funerals.
