Forms

apostasia f (genitive apostasiae); first declension.[1][2] The Greek accusative apostasian occurs in the Latin Irenaeus.[3]

Etymology

It is borrowed from Ancient Greek ἀποστασία (apostasía).[1][4][5][6] Conte calls both the Latin word and its Greek source late.[7]

Earliest recorded meaning

It is first found in Christian writers: the Latin translation of Irenaeus,[3][2] and Ambrosiaster, in the last third of the 4th century AD,[8] who uses it of the fall of Lucifer from heaven.[3]

Semantic evolution

The word meant a falling away from God or from the faith:[1][4] Augustine speaks of the apostasia of the first man,[3] and Salvian uses it of departure from one's religion.[1]

In Medieval Latin it also named heresy and schism,[4] a cleric's breach of duty or defiance of church authority,[5] and the breaking of monastic vows or desertion of a monastery.[6][4][5] English writers used it for the renunciation of the Jewish faith too, and for giving up a vocation.[5] English borrowed it in the late 14th century as apostasie.[9]
