Strongly guarded as is the separation between Religion and Government in the Constitution of the United States, the danger of encroachment by Ecclesiastical Bodies, may be illustrated by precedents already furnished in their short history.
- James Madison; Monopolies, Perpetuities, Corporations, Ecclesiastical Endowments
Who does not see that the same authority which can establish Christianity, in exclusion of all other Religions, may establish with the same ease any particular sect of Christians, in exclusion of all other Sects? that the same authority which can force a citizen to contribute three pence only of his property for the support of any one establishment, may force him to conform to any other establishment in all cases whatsoever?

If Religion be not within the cognizance of Civil Government how can its legal establishment be necessary to Civil Government? What influence in fact have ecclesiastical establishments had on Civil Society? In some instances they have been seen to erect a spiritual tyranny on the ruins of the Civil authority; in many instances they have been seen upholding the thrones of political tyranny: in no instance have they been seen the guardians of the liberties of the people. Rulers who wished to subvert the public liberty, may have found an established Clergy convenient auxiliaries. A just Government instituted to secure & perpetuate it needs them not. Such a Government will be best supported by protecting every Citizen in the enjoyment of his Religion with the same equal hand which protects his person and his property; by neither invading the equal rights of any Sect, nor suffering any Sect to invade those of another.

The settled opinion here is, that religion is essentially distinct from civil Government, and exempt from its cognizance; that a connection between them is injurious to both;
- James Madison; Letter to Edward Everett, March 18, 1823
Nothwithstanding the general progress made within the two last centuries in favour of this branch of liberty, & the full establishment of it, in some parts of our Country, there remains in others a strong bias towards the old error, that without some sort of alliance or coalition between Gov' & Religion neither can be duly supported: Such indeed is the tendency to such a coalition, and such its corrupting influence on both the parties, that the danger cannot be too carefully guarded agst.. And in a Gov' of opinion, like ours, the only effectual guard must be found in the soundness and stability of the general opinion on the subject. Every new & successful example therefore of a perfect separation between ecclesiastical and civil matters, is of importance. And I have no doubt that every new example, will succeed, as every past one has done, in shewing that religion & Gov will both exist in greater purity, the less they are mixed together;
