Bellarmine helped persecute Galileo. I highly doubt he was the inspiration for Madison, Jefferson, and our other founders who were devotees of science, the enlightenment, and of the age of reason.
Please show any founders references to Bellarmine who had no problem telling Galileo that heliocentricism was not allowed to be pursued or defended after the council of Trent. I see no works of his defending the right of the individual over despotism, which of course is the bare essence of the constitution.
The article is weak for that error.
You are correct. Neither Bellarmine nor Aquinas were liberals (in the classical sense of term). Both strongly supported the concept of enlightened monarchical rule and took a generally dim view of Democratic government, as did most educated people from that period. They were after all students of history and knew that Democracy has a very poor long term track record. Aquinas in particular, while conceding a right to depose a truly egregious tyrant, believed that bad rulers, even very bad rulers should be tolerated because their authority came from God (as distinct from a Divine Right to rule). He believed that revolt was morally permissible only in the most extraordinary cases of gross and intolerable tyranny. A position similarly held by Edmund Burke the father of modern conservatism. If you have not read them, I strongly recommend his reflections on the French Revolution.
