These two preliminary sessions were given over almost entirely to a discussion of the procedure that should be followed. In the end it was agreed that the legates should propose to the council the questions on which a decision should be given, that these questions should be examined by committees of bishops aided by theologians and jurists, that the results of these discussions should be brought before a full congregation of the bishops, and that when a decision had been agreed to the formal decrees should be promulgated in a public session. The novel method of voting by nations, introduced for the first time at Constance and Basle, was rejected in favour of individual voting, a definitive vote being allowed only to bishops, generals of religious orders and abbots (one vote to every three abbots). Procurators of absent bishops were not allowed to vote, though later on a special concession was made in favour of some German bishops detained at home by the serious religious condition of their dioceses. The legates were anxious that the dogmatic issues raised by the Lutherans should be dealt with at once, while the Emperor was strongly in favour of beginning with a comprehensive scheme of reform. By this time he had made up his mind to put down his opponents in Germany by force of arms, and he believed that if nothing were done in the meantime to widen the breach the defeat of the Lutheran princes might make them more willing to take part in the council. As a compromise it was agreed that doctrine and discipline should be discussed simultaneously, and, hence, at most of the public sessions two decrees were published, one on matters of faith, the other on reform (/De Reformatione/). It was only at the 4th public session (8th April 1546) that the first doctrinal decree could be issued. Since the Lutherans had called in question the value of Tradition as a source of divine revelation, and had denied the canonicity of several books accepted hitherto as inspired, it was fitting that the council should begin its work by defining that revelation has been handed down by Tradition as well as by the Scriptures, of which latter God is the author both as regards the Old Testament and the New. In accordance with the decrees of previous councils a list of the canonical books of the Scriptures was drawn up. Furthermore, it was defined that the sacred writings should not be interpreted against the meaning attached to them by the Church, nor against the unanimous consent of the Fathers, that the Vulgate Version, a revised edition of which should be published immediately, is authentic, that is to say, accurate as regards faith and morals, and that for the future no one was to print, publish, or retain an edition of the Scriptures unless it had been approved by the local bishop.
