The Roman Catholic Church's primary reaction to the ideas developed by Galileo and other scientists during the Scientific Revolution was one of controversy and resistance. The Church viewed many of these ideas, particularly those contradicting traditional interpretations of Scripture, as a challenge to its authority and established beliefs. Galileo's advocacy for heliocentrism (the idea that the Earth orbits the Sun) directly conflicted with the geocentric view that was widely accepted at the time, which positioned the Earth at the center of the universe.
The Church's response culminated in the trial of Galileo in 1633, where he was found "vehemently suspect of heresy" for promoting heliocentrism and was forced to recant his views. The Church's reaction was largely motivated by a desire to preserve its doctrinal authority and the fear that the acceptance of such scientific ideas could undermine the religious beliefs of the time. Overall, the Church's reaction exemplified a broader struggle between faith and reason during this transformative period in history.
