late 14c., scisme, "dissension within the church," from Old French scisme, cisme "a cleft, split" (12c.), from Church Latin schisma, from Greek skhisma (genitive skhismatos) "division, cleft," in New Testament applied metaphorically to divisions in the Church (I Corinthians xii.25),
from stem of skhizein "to split" (from PIE root *skei- "to cut, split"). Spelling restored 16c., but pronunciation unchanged. Often in reference to the Great Schism (1378-1417) in the Western Church."
