Athinganoi

The Athinganoi (Ancient Greek: Ἀθίγγανοι, singular Athinganos, Ἀθίγγανος, Atsinganoi) were a Manichaean sect^[1] regarded as Judaizing heretics who lived in Phrygia and Lycaonia but were neither Hebrews nor Gentiles. They kept the Sabbath, but were not circumcised. They were Shomer nagia.^[2]

Other sources mentioned that the Athinganoi were Simonians, and had nothing to do with the Manichean or Paulinic sect, and settled in the year of the East–West Schism in 1054 at Byzantium, and married Byzantine women, adopted Greek Orthodox Christianity and later assimilated in Slavic and Greek Population.^[3] In some studies the Athinganoi are described as remnants of the Indo-Greeks who left India in 400 AD during the Migration period.^[4]
