The trial by the Congregation moved to its conclusion. Several of the ten cardinals apparently pushed for Galileo‘s incarceration in prison, while those more supportive of Galileo argued that–with changes–the Dialogue ought to continue to be allowed to circulate. In the end, a majority of the cardinals–rejecting much of the Commissary‘s agreement with Galileo–demanded Galileo „even with the threat of torture…abjure in a plenary assembly of the Congregation of the Holy Office…[and] then be condemned to imprisonment at the pleasure of the Holy Congregation.“ Moreover, the cardinals declared, the Dialogue „is to be prohibited.“
The grand play ran its course, with the Pope insisting upon a formal sentence, a tough examination of Galileo, public abjuration, and „formal prison.“ Galileo was forced to appear once again for formal questioning about his true feelings concerning the Copernican system. Galileo obliged, so as not to risk being branded a heretic, testifying that „I held, as I still hold, as most true and indisputable, the opinion of Ptolemy, that is to say, the stability of the Earth and the motion of the Sun.“ Galileo‘s renunciation of Copernicanism ended with the words, „I affirm, therefore, on my conscience, that I do not now hold the condemned opinion and have not held it since the decision of authorities….I am here in your hands–do with me what you please.“
