SabiansThe Sabians, sometimes also spelled Sabaeans or Sabeans, are a mysterious religious group mentioned three times in the Quran (as الصابئون ALA, in later sources الصابئة ALA), where it is implied that they belonged to the 'People of the Book' (ahl al-kitāb). Their original identity, which seems to have been forgotten at an early date, has been called an "unsolved Quranic problem". Modern scholars have variously identified them as Mandaeans, Manichaeans, Sabaeans, Elchasaites, Archontics, ḥunafāʾ (either as a type of Gnostics or as "sectarians"), or as adherents of the astral religion of Harran.
ArchonticsThe Archontics, or Archontici, were a Gnostic sect that existed in Palestine, Syria and Armenia, who arose towards the mid 4th century CE. They were thus called from the Greek word ἄρχοντες, "principalities", or "rulers", by reason that they held the world to have been created and ruled by malevolent Archons. Epiphanius of Salamis seems to be the earliest Christian writer who speaks of this sect. He relates that a young priest in Palestine named Peter had been charged with heresy, deposed from the office of the priesthood and expelled by Bishop Aëtius.
MonophysitismMonophysitism (məˈnɒfɪsaɪˌtɪzəm or məˈnɒfɪsɪˌtɪzəm) or monophysism (məˈnɒfɪzɪzəm) (from Greek μόνος , "solitary" and φύσις , "nature") is a Christology that states that the person of the incarnated Word (that is, in Jesus Christ) there was only one nature—the divine". The First Council of Nicaea (325) declared that Christ was divine (homoousios, consubstantial, of one being or essence, with the Father) and human (was incarnate and became man).
