The doctrine of heresy is validated by the consistent warnings in Scripture against teachings that deviate from apostolic doctrine.
Heretical doctrines are identified in the Bible as beliefs or practices that lead to schism and division within the church. The New Testament provides warnings about false teachers and heresies that arise, as evidenced in 1 and 2 Timothy where Paul highlights the rapid spread of false teachings (1 Timothy 2:18). Heresy is not limited to obvious deviations; it encompasses any teaching that undermines the original gospel, as heresies throughout history have evolved but fundamentally retained the same principles of deception aimed at nullifying grace. Paul emphasizes the danger of these teachings, alerting believers of their divisive nature.
