I guess I'm not following this. Not working on Sundays was never a "traditional practice", it was and still is Divine Law. When did Francis think this changed?
Clearly God's laws have not changed,aand the Pope has not forgotten the 10 Commandments. What he means is society-wide, the whole society has abandoned what it traditionally observed, i.e. the "Honor the Lord's Day" commandment ---- even state offices and businesses/commercial outlets run by secular or non-Christian people.
And he doesn't think this society-wide abandment of our Christian traditions is a good thing.
I expect you'd agree.
Where is this in the Bible ?
