In the Royal Letter which the Bohemians had extorted from Rodolph II., as well as in the German religious treaty, one material article remained undetermined. All the privileges granted by the latter to the Protestants, were conceived in favour of the Estates or governing bodies, not of the subjects; for only to those of the ecclesiastical states had a toleration, and that precarious, been conceded. The Bohemian Letter of Majesty, in the same manner, spoke only of the Estates and imperial towns, the magistrates of which had contrived to obtain equal privileges with the former. These alone were free to erect churches and schools, and openly to celebrate their Protestant worship; in all other towns, it was left entirely to the government to which they belonged, to determine the religion of the inhabitants. The Estates of the Empire had availed themselves of this privilege in its fullest extent; the secular indeed without opposition; while the ecclesiastical, in whose case the declaration of Ferdinand had limited this privilege, disputed, not without reason, the validity of that limitation. What was a disputed point in the religious treaty, was left still more doubtful in the Letter of Majesty; in the former, the construction was not doubtful, but it was a question how far obedience might be compulsory; in the latter, the interpretation was left to the states. The subjects of the ecclesiastical Estates in Bohemia thought themselves entitled to the same rights which the declaration of Ferdinand secured to the subjects of German bishops, they considered themselves on an equality with the subjects of imperial towns, because they looked upon the ecclesiastical property as part of the royal demesnes. In the little town of Klostergrab, subject to the Archbishop of Prague; and in Braunau, which belonged to the abbot of that monastery, churches were founded by the Protestants, and completed notwithstanding the opposition of their superiors, and the disapprobation of the Emperor.
