The public Spitzer persona I knew

"I consider the government of the United States as interdicted by the Constitution from intermeddling in religious institutions, their doctrines, discipline, or exercises...Certainly, no power to prescribe any religious exercise or to assume authority in religious discipline has been delegated to the General Government...

"But it is only proposed that I should recommend, not prescribe a day of fasting and prayer. That is, that I should indirectly assume to the U.S. an authority over religious exercises which the Constitution has directly precluded them from.... I do not believe it is for the interest of religion to invite the civil magistrate to direct it's exercises, it's discipline, or it's doctrines; nor of the religious societies that the general government should be invested with the power of effecting any uniformity of time or matter among them. Fasting and prayer are religious exercises. The enjoining them an act of discipline. Every religious society has a right to determine for itself the times for these exercises, and the objects proper for them, according to their own particular tenets; and this right can never be safer than in their own hands, where the constitution has deposited it...every one must act according to the dictates of his own reason, and mine tells me that civil powers alone have been given to the President of the U.S. and no authority to direct the religious exercises of his constituents."
