Pope Paul III, however, was not sitting idle in this rapidly changing climate. In 1542, after a failed attempt to conciliate Roman Catholics and Protestants at the Diet of Regensburg, he agreed on renewing the earlier practice of the Roman Inquisition under the oversight of the zealous Cardinal Giampietro Carafa. Anything that suggested echoes of European Reformers was now subject to rigorous scrutiny.
When Vermigli got news that an invitation by church officials to a meeting in Genoa, Italy, was really a call to an interrogation, he realized he had three options: deny (at least outwardly) his faith, face the possibility of torture and death, or flee. He chose the third one. At least he could continue to teach and preach abroad.
