Madison is not only the Father of the Constitution and the Father of the Bill of Rights, but also perhaps the greatest advocate for the separation of state and church. “Every new & successful example therefore of a perfect separation between ecclesiastical and civil matters, is of importance;” he wrote in 1822, adding, “And I have no doubt that every new example, will succeed, as every past one has done, in showing that religion & Govt. will both exist in greater purity, the less they are mixed together.”
