Why were no people praying in Paris? (From Book 3 Chapters 6-10)

People no longer prayed because they were disillusioned by many representatives of the Church.

With a solemn interest in the lighted windows where the people were going to rest, forgetful through a few calm hours of the horrors surrounding them; in the towers of the churches, where no prayers were said, for the popular revulsion had even travelled that length of self-destruction from years of priestly impostors, plunderers, and profligates; in the distant burial-places, reserved, as they wrote upon the gates, for Eternal Sleep; in the abounding gaols; and in the streets along which the sixties rolled to a death which had become so common and material, that no sorrowful story of a haunting Spirit ever arose among the people out of all the working of the Guillotine; with a solemn interest in the whole life and death of the city settling down to its short nightly pause in fury; Sydney Carton crossed the Seine again for the lighter streets.
