James Madison
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; (James Madison, letter to Edward Livingston, July 10, 1822, The Writings of James Madison, Gaillard Hunt)
An alliance or coalition between Government and religion cannot be too carefully guarded against......Every new and successful example therefore of a PERFECT SEPARATION between ecclesiastical and civil matters is of importance........religion and government will exist in greater purity, without (rather) than with the aid of government. (James Madison in a letter to Livingston, 1822, from Leonard W. Levy- The Establishment Clause, Religion and the First Amlendment, pg 124)

Freedom arises from the multiplicity of sects, which prevades America and which is the best and only security for religious liberty in any society. For where there is such a variety of sects, there cannot be a majority of any one sect to oppress and persecute the rest. (James Madison, spoken at the Virginia convention on ratifying the Constitution, June 1778)
Strongly guarded... is the separation between religion and government in the Constitution of the United States.
The purpose of separation of church and state is to keep forever from these shores the ceaseless strife that has soaked the soil of Europe in blood for centuries.
