The civil institutions of the United States could not have been formed without the separation of Church and State, and could not continue to exist if they were again united. Christianity could not maintain its primitive purity if politics and religious faith were mingled together; nor could the State preserve its capacity to provide for the general welfare if subjected to the dominion of ecclesiastical authority. Our success as a nation is mainly attributable to the fact that these sentiments are deeply imbedded in the American mind.
A party pledged to restore to the pope the temporal power which the Italian people have taken away, must necessarily be politico-religious in character, because it proposes to interfere with the temporal affairs of one of the European nations. And if the attempt to do this is justified upon the ground that such restoration involves religious duty, any one can see that the obligation is the same in the United States as in Italy, for the laws of God do not shift to suit the exigencies of human affairs.
In the times before the Reformation the temporal affairs of Governments were required to conform to the commands of the ecclesiastical authority—that is, the pope—and it was held to be a necessary and essential part of religion that this union should be continued, no matter what might be the degree of popular ignorance and humiliation. The founders of our Government started out upon a different theory, believing it to be[Pg 4] their duty to separate "the things of God" from "the things of Cæsar," so that each could reach perfection in its own distinct sphere. Therefore, it is clear that a politico-religious party in this country, pledged to unite Church and State in Italy, against the expressed will of the Italian people, not only must oppose one of the fundamental principles of our Government, but disturb the public peace.
To my mind it is also clear that a nation acts politically, and not religiously, when it decides upon the structure of its temporal Government—that is, whether its affairs shall be managed by an absolute or elective monarch, or by machinery provided by a written constitution. I have, therefore, refrained from the discussion or criticism of religious belief—as it is understood in the American sense—any further than it is made the pretext for the reversal of this opinion, so generally prevalent in this country. It would be an evil day for the people of the United States if they should be persuaded to permit any power whatsoever, whether temporal or spiritual, at home or abroad, to share with them any portion of their political authority, or to dictate, in any degree, the measures of their civil polity.
