On this day in History

January 29, 1523: Before an audience of more than 600 people gathered at the first Zurich Disputation, Swiss reformer Ulrich Zwingli successfully defends his 67 theses. He appealed only to Scripture and rejected the authority of the pope, the sacrifice of the Mass, the invocation of saints, times and seasons of fasting, and clerical celibacy. But the city council nevertheless declared 'that Master Ulrich Zwingli (may) continue to preach the Holy Gospel and the true divine Scripture as he has done until now for as long a time and to such an extent until he be instructed differently' (see issue 4: Ulrich Zwingli).
