The six weighted criteria

• Textual fidelity — preservation, manuscript count, and accuracy of source documents.
• Historical verification — independent corroboration, hostile-witness testimony, archaeological confirmation.
• Scientific testability — falsifiable claims, observable evidence, repeatable predictions.
• Internal consistency — logical coherence of doctrine and absence of contradiction.
• Prophetic accuracy — ratio of fulfilled to unfulfilled predictions, dated against earliest manuscripts.
• Explanatory power — how well the system accounts for the breadth of human experience.
