[1] By the end of the 1530s he had probably already embraced the Reformation, based on the fact that he urged Flacius to go study in Germany instead of Venice.
Thereafter, Baldo went to preach in Cres several times, since as early as 1535, invited by the council of the island, wherein Stefano Patrizi held a prominent position.
[1] Although he had found support on the island, even that of some of its prominent citizens, Baldo found an obstacle in Giacomo Curzolan, a Venetian chancellor, who denounced him to the Venetian authorities in October 1541, after he heard him deny several points of the Catholic dogma in his sermon for Lent.
On June 26, 1543, Flacius went from Wittenberg to Venice to present a letter signed by the leaders of the Schmalkaldic League to the Venetian authorities, on the behalf of his uncle-in-law.
Baldo continued to preach during his imprisonment, and as a result he was punished with his meals being reduced to bread and water for five months.
