  • Equality and Anti-Authoritarianism

    Paine links religious equality (the way to God open to all) with political equality, opposing monarchy, hereditary privilege, and any claim of divine favoritism toward a chosen group.

    Paine systematically examines biblical texts—such as the prophecies in Isaiah and the story of Jesus—to argue they are fabrications, contradictions, or misinterpretations, not divine revelation.
