(Erratum: the Enlightenment was essentially an 18th century affair) What it demonstrated was that the fixtures of monarchy and religious power were working against the interests of the French population in particular, and were outmoded generally. In principle these two evils were highly undemocratic since they favoured the rich and perpetuated their entitlement to undue privilege. The philosophes offered reason as a substitute for religious superstition.
It might be said that early Christianity attempted to create a God centered society and by the fifth century it was being enforced as a political instrument in the ailing Late Roman Empire. In reality Christianity's weaknesses were apparent right from the start. There are very few contemporary secular texts on the subject but one from the early second century by the Stoic and rationalist Epictetus (pron; epic teetus) called the Jesus Christians "Galileans" to distinguish them from other christian sects. He felt a philosophical sympathy with their calmness in facing death but noted their passivity and gullibility in believing holy things.
Christianity like all irrational belief has a lot to answer for. The response has got to be the the Enlightenment ideal of reason before faith.
