GNOSTICISM: Guard Against Falsely Called Knowledge—How Important Is Truth to You?

Gnosticism heresy is a collection of ancient religious ideas and systems which originated in the first century AD among early Christian and Jewish sects. These various groups emphasized personal spiritual knowledge over orthodox teachings, traditions, and ecclesiastical authority.
The Gnostics (Greek gnosis, meaning “knowledge”) maintained they had superior knowledge by way of secret revelation and bragged that they were the “correctors of the apostles.” Gnosticism weaved philosophy, speculation, and pagan mysticism with apostate (false) Christianity.
