"From this follows the obligation of the cessation from work and labor on Sundays

"From this follows the obligation of the cessation from work and labor on Sundays and certain holy days. The rest from labor is not to be understood as mere giving way to idleness; much less must it be an occasion for spending money and for vicious indulgence, as many would have it to be; but it should be rest from labor, hallowed by religion."

– Leo XIII, Rerum Novarum, 41
