Did I not mention no unnecessary servile (paid or manual) work? That’s what the catechism says. You can read it for yourself. That’s a biggie for most people right there, many couldn’t sit still if you tried to sit ON 'em to keep 'em still.
And you say ‘as long as you go to Mass’ as if it’s an afterthought. Many of the people I talk to make it seem like a necessary chore and not a desired activity. Spending time worshipping God in Mass is certainly a great gift of time and presence that we give to God. Not only a gift but a requirement. It doesn’t preclude the doing of other things on the same day y’know! Family time if it is your only day off then time spent with those you don’t see all week. Play with your children and grandchildren. Turn off the "tube’ and get to know you family again.
What do you think we should do on Sundays, sit at home on our couches, stare at blank walls and twiddle our thumbs for 12 hours or so and then go to bed? Nope rest and relaxation is not sitting on the couch and twiddeling your thumbs. Play ball with the kids, taking a walk with your spouse and talking to each other would be nice. A family meal with all home. That’d make it quiet, non-commercial, sure, but any holier? If you spent a bit of filthy lucre to, say, see The Passion of Christ, or a religious art exhibition or a beautiful garden that lifted your mind up to God, that would be much more in keeping with the spirit of the Sabbath. I never said anything about “filty lucre” or the moneychangers. All I said was that commerice could be done durring ithe week and did not “need” to be done Sunday.
It’s day to worship God, and to rest and relax, as He did. Often we rest and relax by doing things, which may but don’t have to involve commerce. But then anything you do unless you stay at home and do nothing is going to involve making someone else work - gasstation clerks, people you visit, rubbish collectors. Can’t yoy get gas the other six days? Or have the rubbish collected then? As for people you visit as long as they welcome you it is not servile.
The point I’m trying to make is that if Sunday is the only time someone can work, or shop, then they’re entitled. God doesn’t want us to starve or have the electricity cut off because we’re scrupulous about Sunday.
