The Leipzig Disputation was the last occasion on which the ancient custom of swearing to advance no tenet contrary to Catholic doctrine was observed. In all subsequent debates between Catholics and Protestants, the bare text of Holy Writ was taken as the authority. This placed the Catholics in a disadvantageous position. This was particularly the case in Switzerland, where Zwingli and his lieutenants organized a number of one-sided debates under the presidency of town councils already won over to Protestantism. Such were the disputations of Zurich, 1523, of Swiss Baden, 1526, and of Berne, 1528. In all of these the result was the abolition of Catholic worship and in their opinion the desecration of churches and religious institutions.
