The real object of the First Amendment was not to countenance, much less advance Mohammedanism, or Judaism or infidelity, by prostrating Christianity; but ... to prevent any national ecclesiastical establishment which should give to a hierarchy the exclusive patronage of the national government.

The militia is the natural defense of a free country against sudden foreign invasions, domestic insurrections, and domestic usurpations of power by rulers. It is against sound policy for a free people to keep up large military establishments and standing armies in time of peace, both from the enormous expenses, with which they are attended, and the facile means, which they afford to ambitious and unprincipled rulers, to subvert the government, or trample upon the rights of the people.

The true test is, whether the object be of a local character, and local use; or, whether it be of general benefit to the states. If it be purely local, congress cannot constitutionally appropriate money for the object.

It should therefore be difficult in a republic to declare war; but not to make peace.

Temporary delusions, prejudices, excitements, and objects have irresistible influence in mere questions of policy. And the policy of one age may ill suit the wishes or the policy of another.

It should be, so far at least as human infirmity will allow, not dependent upon the passions or parties of particular times, but the same yesterday, to-day, and for ever.
