We may be assured by past experience, that such a practice [as some states charging high taxes on goods from other states] would be introduced by future contrivances; and both by that and a common knowledge of human affairs, that it would nourish unceasing animosities, and not improbably terminate in serious interruptions of the public tranquility.

The civil Government, though bereft of every thing 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.

The civil rights of none, shall be abridged on account of religious belief or worship, nor shall any national religion be established, nor shall the full and equal rights of conscience be in any manner, or on any pretext infringed.

The danger of disturbing the public tranquillity by interesting too strongly the public passions, is a still more serious objection against a frequent reference of constitutional questions to the decision of the whole society.

Nor is any evidence to be found, either in History or Human Nature, that nations are to be bribed out of a spirit of encroachment and aggression, by humiliations which nourish their pride, or by concessions that extend their resources and power.

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.
