This week's heresy is one of the Gnostic heresies about which we know a good deal.
Peratism, meaning “to pass through” is a 2nd century Ophitism Gnosticism sect related to Borboritism, Mandaeism, Naassenism, and Sethianism. Little has survived about this sect other than in the writings of one early church father. They were largely focused on astrology and the influence of stars and planets on man, with many myths about the planets. It appears that they believed in a Trinitarian-like God with three divisions or “principles”: Pater (the Father, who was perfect goodness and unbegotten), Uios (the Son, considered to be the Word and the Serpent) and Hyle (the Spirit, who was fashioned by the Father but is without form). They seem to largely follow the redemption story of the Bible. The Serpent (meaning the Son) attracts to himself the “likeminded” (like iron is attracted to a magnet), who are called “Paratae”. The Paratae are those who have learned through gnosis how “to pass through” the corruption to which every created being is subjected. The ignorant were known by Peratians as “Egyptians”.
