Deuteronomy 13:1-5

The context

Deuteronomy 13 follows the warnings of chapter 12 about adopting Canaanite worship. It sets out three cases: a prophet who works a sign, a family member who whispers an invitation, and a whole town that turns aside. The first case is the hardest, because the sign is said to come true.

What it establishes

The passage establishes a test of loyalty rather than a test of power. A fulfilled prediction does not validate a message that leads away from the LORD; the criterion is the direction of the teaching, not the accuracy of the sign. That ordering is the chapter's contribution.

What it does not establish

It does not provide a general method for testing claims. The passage addresses one error, apostasy to other gods, and presupposes a community with authority to judge. It does not tell a reader how to weigh a teacher wrong on a secondary matter, and it does not authorize private enforcement.

• If a father ever killed his own son he would—all things being equal—be rightly judged immoral. But according to Genesis 22, God told Abraham to kill his own son, and was judged righteous for his WILLINGNESS to do so. So God ordains child murder, huh?
