Vermigli was summoned to a Chapter Extraordinary of the Lateran Congregation, and his friends warned him that he had powerful adversaries. These increasingly foreboding events contributed to his decision to ignore the summons and flee, but he was finally persuaded by his conscience against the Masses he was bound to perform. Vermigli fled Lucca for Pisa on 12 August 1542 by horse with three of his canons. There he celebrated a Protestant form of the Eucharist for the first time. When he stopped in Florence, staying in Badia Fiesolana where he had entered religious life, Vermigli learned that Bernardino Ochino had arrived there. Vermigli convinced Ochino, a popular preacher with Protestant leanings, to flee Italy as well. On 25 August Vermigli left for Zürich by way of Ferrara and Verona.
