"...Sunday is the property of our good God; it is His own day, the Lord's day. He made all the days of the week: He might have kept them all; He has given you six, and has reserved only the seventh for Himself. What right have you to meddle with what does not belong to you?

I know two very certain ways of becoming poor: they are working on Sunday and taking other people's property..."Source: Day 7 February 23rd, 2010
