Pronunciation

  • IPA (Classical): [ˈhae̯.rɛ.sɪs][1]
  • IPA (Ecclesiastical): [ˈɛː.re.s̬is][1]

Forms

haeresis f (genitive haeresis or haereseōs or haeresios); third declension[1]

Etymology

It is borrowed from Ancient Greek αἵρεσις (haíresis, “choice; sect”).[2][1][3] Tertullian and Jerome explain the name from the Greek for “choice”, and Isidore of Seville says it is so called because each person chooses what seems best to him.[4][5]

Earliest recorded meaning

Varro speaks of a new school and of the Menippean school.[6] Köbler dates Varro 116–27 BC.[7]

Semantic evolution

It meant a philosophical school or sect, the pure Latin being secta: Cicero says that Cato belongs to the school that seeks no ornament of speech, and Vitruvius speaks of following Pythagoras' school.[2][8][6] Cicero also jokes about Vestorius' trade as his haeresis.[8]

From Tertullian on it was heretical religious doctrine, heresy, as Lactantius' many sects and heresies and Sidonius' Arian heresy.[8][9] Isidore of Seville applies it both to the philosophical schools and to those who left the Church for a perverse dogma.[5] The Theodosian Code uses it of a calling or trade.[8] Medieval Latin used it of heretical doctrine and sects, and of a fine for heresy.[10] English heresy came from Old French about 1200.[11]
