The powers of the federal government ... result from the compact to which the states are parties, [and are] limited by the plain sense and intention of the instrument constituting that compact.

I have received your letter of the 6th, with the eloquent discourse delivered at the consecration of the Jewish Synagogue. Having ever regarded the freedom of religious opinions and worship as equally belonging to every sect, and the secure enjoyment of it as the best human provision for bringing all either into the same way of thinking, or into that mutual charity which is the only substitute, I observe with pleasure the view you give of the spirit in which your sect partake of the blessings offered by our Government and laws.

It is to the press mankind are indebted for having dispelled the clouds which so long encompassed religion, for disclosing her genuine lustre, and disseminating her salutary doctrines.

Those who proposed the Constitution knew, and those who ratified the Constitution also knew that this is...a limited government tied down to specified powers....It was never supposed or suspected that the old Congress could give away the money of the states to encourage agriculture or for any other purpose they pleased.

If it be asked what is to restrain the House of Representatives from making legal discriminations in favor of themselves and a particular class of the society? I answer, the genius of the whole system, the nature of just and constitutional laws, and above all the vigilant and manly spirit which actuates the people of America, a spirit which nourishes freedom, and in return is nourished by it.

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. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself. A dependence on the people is, no doubt, the primary control on the government; but experience has taught mankind the necessity of auxiliary precautions.

[T]he bill exceeds the rightful authority to which governments are limited by the essential distinction between civil and religious functions, and violates in particular the article of the Constitution of the United States which declares that Congress shall make no law respecting a religious establishment.... This particular church, therefore, would so far be a religious establishment by law, a legal force and sanction being given to certain articles in its constitution and administration.
