Why were the  philosophes  against the catholic church’s role in french politics?

he French Catholic Church, known as the Gallican Church, recognised the authority of the pope as head of the Roman Catholic Church but had negotiated certain liberties that privileged the authority of the French monarch, giving it a distinct national identity characterised by considerable autonomy. France’s population of 28 million was almost entirely Catholic, with full membership of the state denied to Protestant and Jewish minorities. Being French effectively meant being Catholic. Yet, by 1794, France’s churches and religious orders were closed down and religious worship suppressed. How did it come to this? What did revolutionaries hope to achieve? And why did Napoleon set out to reverse the situation?

Herodotus taught that absolute right and wrong did exist.
