Vermigli was widely respected and very cautious. He was able to continue his reform efforts in Lucca without any suspicion of unorthodox views, despite a papal meeting there with Emperor Charles V in 1541. His eventual downfall was caused by two of his followers, one of whom openly questioned papal authority and another who celebrated a Protestant form of the Eucharist. The reconstitution of the Roman Inquisition in 1542 may have been in part a response to fear that Lucca and other cities would defect from the Catholic Church. The authorities of the Republic of Lucca began to fear that their political independence from the Holy Roman Empire was at stake if their city continued to be viewed as a Protestant haven. Bans on Protestant books heretofore ignored were enforced, religious feasts which had been dropped were reinstated, and religious processions were scheduled to assure Rome of Lucca's loyalty.
