Here is the part to bear in mind when imparting the profundity of the founders to future freethinkers:
Notwithstanding 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 Govt. & 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 Govt. 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 & Govt. will both exist in greater purity, the less they are mixed together.
Perfect separation! Not partial separation, not merely neutrality in funding various religious programs, but perfect, utter, absolute separation between affairs of state and church.
