Gnosticism & Christian Heresies
Gnosticism was considered a heretical form of early Christianity that developed during the 1st and 2nd centuries CE. Until 1945, most of what scholars knew about Gnosticism came from the passionate debates and condemnations from the Early Church Fathers (aka the opponents of Gnostic theologians). In 1945, a large collection of manuscripts – including the Gospel of Thomas – now known as the Nag Hammadi corpus was found. Read articles about Gnosticism below.
