As nouns the difference between excommunication and disfellowshipment

is that excommunication is the act of excommunicating or ejecting; especially an ecclesiastical censure whereby the person against whom it is pronounced is, for the time, cast out of the communication of the church; exclusion from fellowship in things spiritual while disfellowshipment is a temporary sanction used within The Church of Jesus Christ of Latter-day Saints, more severe than formal probation but less severe than excommunication.
