Why is galileo a heretic

Galileo agreed and confessed that he had given stronger arguments to the heliocentric proponent in his dialogue than to the geocentric champion. But he insisted that he did not do so because he himself believed in heliocentrism, Kelly said. Rather, he claimed he was simply showing off his debating skills. Galileo was never tortured, however. The pope decreed that the interrogation should stop short with the mere threat of torture. He died in In his later years Galileo insisted on the truth of the geocentric solar system, Kelly said.

Jessica Wolf December 22, He shared a copy of this softened version with a friend, claiming it was his original, and urged him to send it to the Vatican. It was rediscovered in the library there by Salvatore Ricciardo, a postdoctoral science historian at the University of Bergamo in Italy, who visited on 2 August for a different purpose, and then browsed the online catalogue. Some science historians declined to comment on the finding before they had scrutinized the article.

Galileo wrote the letter to Benedetto Castelli, a mathematician at the University of Pisa in Italy. He argued that the scant references in the Bible to astronomical events should not be taken literally, because scribes had simplified these descriptions so that they could be understood by common people.

Most crucially, he reasoned that the heliocentric model of Earth orbiting the Sun, proposed by Polish astronomer Nicolaus Copernicus 70 years earlier, is not actually incompatible with the Bible. Galileo, who by then was living in Florence, wrote thousands of letters, many of which are scientific treatises. Copies of the most significant were immediately made by different readers and widely circulated. Of the two versions known to survive, one is now held in the Vatican Secret Archives.

Galileo enclosed with that letter a less inflammatory version of the document, which he said was the correct one, and asked Dini to pass it on to Vatican theologians. At least a dozen copies of the version Galileo sent to Dini are now held in different collections. The changes are telling. This suggests that Galileo moderated his own text, says Giudice. Bruno is burnt at the stake. Copies of this letter are circulated. Books supporting the Copernican model are banned.
