No.
"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)
"It was the Universal opinion of the Century preceding the last, that Civil Government could not stand without the prop of a religious establishment; and that the Christian religion itself, would perish if not supported by the legal provision for its clergy. The experience of Virginia conspiciously corroboates the disproof of both opinions. The Civil Government, tho' bereft of everything like an associated hierarchy, possesses the requisite stability and performs its functions with complete success; whilst the number, the industry, and the morality of the priesthood, and the devotion of the people have been manifestly increased by the total separation of the Church from the State." - James Madison
"Whilst we assert for ourselves a freedom to embrace, to profess and observe the Religion which we believe to be of divine origin, we cannot deny equal freedom to those whose minds have not yet yielded to the evidence which has convinced us. If this freedom be abused, it is an offense against God, not against man: To God, therefore, not to man, must an account of it be rendered." - James Madison
Oh, and let's have a little Thomas Jefferson while we're at it.
"If we did a good act merely from the love of God and a belief that is pleasing to him, whence arises the morality of the Atheist? It is idle to say, as some do, that no such being exists [...] Diderot, D'Alembert, D'Holbach, Condorcet are known to have been among the most virtuous of men. Their virtue, then, must have had some other foundation than love of God." -
Thomas Jefferson, letter to Thomas Law, June 13, 1814
