The final question to completely sever ties between the radicals and Zwingli was the question of infant baptism. A public debate was held on 17 January 1525. Zwingli argued against Grebel, Manz and George Blaurock. The city council decided in favor of Zwingli and infant baptism, ordered the Grebel group to cease their activities, and ordered that any unbaptized infants must be submitted for baptism within 8 days. Failure to comply with the council's order would result in exile from the canton. Grebel had an infant daughter, Issabella, who had not been baptized, and he resolutely stood his ground. He did not intend for her to be baptized.
