"If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary." - James Madision, The Federalist Papers No. 51
Guiding Principles in Which to Root Pragmatic Policy
The sole purpose of government is to defend the inalienable rights of mankind, the God-given rights of life, liberty, and property.
All government has authority by the consent of the governed. Men cannot grant government authority they themselves do not have. If private individuals do not have the moral authority to commit an act, then they cannot grant government that authority. Mankind's authority comes endowed solely from God, who retains sole authority over all the universe.
All mankind are imperfect beings in need of God's grace. This includes the general population, government bureaucrats, and politicians at all levels of government. The Founding Generation thus established the federalist system, ensuring that no single person or governmental entity wields too much power. Political authority is (should be) dispersed between the three branches of the federal government, the states, local governments, the Church, and the people. Each should play its own unique role without infringing upon the sovereign role of the others.
As we are all created in God's image, Justice for all means just that: justice for ALL.
