Apostasy

Apostasy ( /əˈpɒstəsi/; Greek: ἀποστασία (apostasia), 'a defection or revolt', from ἀπό, apo, 'away, apart', στάσις, stasis, 'stand, 'standing') is the formal disaffiliation from or abandonment or renunciation of a religion by a person. One who commits apostasy (or who apostatises) is known as an apostate. The term apostasy is used by sociologists to mean renunciation and criticism of, or opposition to, a person's former religion, in a technical sense and without pejorative connotation.
