[W]e may classify heresies into six major categories:

1. Heresies about revelation — teachings that distort, deny, or add to Scripture in a way that leads people to destruction; false claims to apostolic or prophetic authority.
2. Heresies about God — teachings that promote false gods or idolatrous distortions of the true God.
3. Heresies about Christ — denials of His unique Lordship, His genuine humanity, His true identity.
4. Heresies about salvation — teaching legalism or licentiousness; denying the gospel of Christ’s death and resurrection; and so forth.
5. Heresies about the church — deliberate attempts to lead people away from the fellowship of true Christians; utter rejection of the church.
6. Heresies about the future — false predictions for which divine authority is claimed; claims that Christ’s return has taken place; and the like.

 

Note that errors in any one of these six categories tend to introduce errors into the other five. Take, for instance, the heretical view held by many groups that the church became totally apostate in the early centuries and thus had to be “restored” in the last days. This doctrine implies (1) that Scripture is not a sufficient revelation, but needs supplementing or “explaining” by some authoritative teacher or publication. It also almost always serves as a basis for rejecting the early church’s views of (2) God and( 3) Christ. Since the Reformation is rejected as falling short of the needed restoration, (4) the doctrine of salvation by grace through faith is likewise rejected. And the doctrine of a restoration comes to dominate the group’s views of (5) the future, as it requires them to view many or most biblical prophecies about the future as finding fulfillment in their own group.
