Zwingle, when he provoked in German Switzerland the rupture with the church of Rome, had approved of the arrangement that the sovereign authority in matters of religion should pass into the hands of the civil powers.

Luther himself, at the same time that he reserved to the new German church a certain measure of spontaneity and liberty, had placed it under the protection and preponderance of laic sovereigns.

In this great question as to the relations between church and state Calvin desired and did more than his predecessors; even before he played any considerable part in the European Reformation, as soon as he heard of Henry VIII.'s religious supremacy in England, he had strongly declared against such a regimen; with an equitable spirit rare in his day, and in spite of his contest with the church of Rome, he was struck with the strength and dignity conferred upon that church by its having an existence distinct from the civil community, and by the independence of its head.

When he himself became a great Reformer, he did not wish the Reformed church to lose this grand characteristic; whilst proclaiming it evangelical, he demanded for it in matters of faith and discipline the independence and special authority which had been possessed by the primitive church; and in spite of the resistance often shown to him by the civil magistrates, in spite of the concessions he was sometimes obliged to make to them, he firmly maintained this principle, and he secured to the Reformed church of Geneva, in purely religious questions and affairs, the right of self-government, according to the faith and the law as they stand written in the Holy Books.
He at the same time put in force in this church a second principle of no less importance.

In the course of ages, and by a series of successive modifications, some natural and others factitious and illegitimate, the Christian church had become, so to speak, cut in two, into the ecclesiastical community and the religious community, the clergy and the worshippers.
