These enactments were an immense advance, practically, but they did not involve the liberty of conscience. The absolute right of the State to determine the religion it professed was not disputed, but it was tempered by the right of emigration. No man could be compelled to change, but he might be compelled to go. State absolutism was unlimited over all who chose to keep their home within the precincts. There was no progress in point of principle. The Christian might have to depart, while the Jew remained. No Protestant could complain if he was expelled from Cologne; no Catholic if he could not have his domicile at Leipzig. The intolerance and fierceness of the Germans found relief in the wholesale burning of witches. Charles V would have nothing to do with these innovations. He left it all to his brother Ferdinand, King of Bohemia and Hungary, who was more elastic and pliable than himself. With the Turk over the border, he could not exist without the goodwill of both parties; and he desired the vote of Lutheran electors to make him emperor. He had no Inquisition in one part of his dominions contradicting and condemning toleration in the rest. He was an earnest promoter of reform in the shape of concession. The embers of Hussitism were not extinct in the region of which Bohemia was the centre. Ferdinand had that as well as Lutheranism to contend with, and he desired to avert peril by allowing priests to marry and laymen to receive the cup. That is to say, he desired to surrender the two points for which the Church had struggled successfully against the State in the eleventh century, against the Bohemians in the fifteenth. His conciliatory policy was assisted by the moderation of the Archbishop of Mentz. At Rome they said that the empire was divided between Christ and the devil. But the Pope, advised by Jesuits, made no protest.
