These three heresies, each subtly undercutting God's truth and plan for mankind, have been recycled since Creation,
effectively continuing the separation from God begun in the Garden of Eden. Certainly, Gnosticism incorporates these foundational falsehoods, but they also exist in every anti-God system of belief, organized or not.
An area where the wrong approach to knowledge becomes apparent is in love toward God and toward fellow man, and especially toward our brethren and families.
The Gnostics tended to disdain those who were not as "enlightened" as they were. Knowledge and understanding were their currency, and they assigned value to people based on what they knew, a practice completely contrary to God's way of outgoing concern.
