As parish priest, Vianney realized that the Revolution's aftermath had resulted in religious ignorance, due to the destruction of the Catholic Church in France. At the time, Sundays in rural areas were spent working in the fields, or dancing and drinking in taverns. Vianney was astonished, especially since Sundays were meant to be reserved for religion.

Remember the Curé of Ars?
