Heresy originally meant choice—placing personal opinion above God’s revealed truth. Throughout history, heresies have taken many forms, but they share a common root: redefining God, Christ, or salvation to fit human philosophy rather than Scripture.

From ancient Gnosticism and Arianism to modern process theology, heresy consistently undermines revelation, incarnation, and God’s authority. When man reshapes theology, truth erodes. Orthodoxy is not rigidity—it is faithfulness to the God who has spoken.
