For lyrics of spirituals, Erskin Peters' Lyrics of the Afro-American Spirituals: A Documentary Collection (Greenwood, 1993) is very helpful. "Scandalize My Name" is on page 37, the source of which is Calhoun Plantation Songs, published in 1901 and 1907. The reprinted edition of the latter (1907; AMS, 1976) contains it on page 65 with the music.
