Which French Enlightenment writer was known for advocating civil liberties and criticizing the Catholic Church?

Voltaire is recognized for his vigorous defense of civil liberties, including freedom of speech and religious tolerance, making significant contributions to Enlightenment thought. He was a fierce critic of the Catholic Church and organized religion, which he believed perpetuated superstition, oppression, and intolerance. Voltaire’s writings often highlighted the importance of reason and empirical evidence, and he used satire to expose the hypocrisy of religious and political institutions. His famous declaration, "Écrasez l'infâme" ("Crush the infamous thing"), reflects his disdain for the dogma and authority of the Church. This advocacy for civil liberties and critique of the Church were foundational to the Enlightenment's call for individual rights and a questioning of traditional authority. The other writers mentioned contributed to Enlightenment thought, but none combined the critique of the Church and a specific focus on civil liberties in quite the same way as Voltaire.
