Is national religion tyrannical? Or could national religion be beneficial or even necessary? Answering those and other questions, Wagner lays out the long-understood but often-disregarded principle of national religion as the Biblical, logical, and historical option for Presbyterians. In so doing, Wagner addresses the futility of those arguing for the moral neutrality of government and other Christians labouring for trivial improvements in existing policy. In a concise manner, Wagner unveils the divine purpose of the civil government as clearly derived from Scripture.
