Alex - regarding your tag line. I recall the story was Knox went to Geneva and was shocked to find Calvin bowling on Sunday afternoon. Did Knox join him in a game?
Calvin’s view of the Lord’s day and Westminster’s were certainly different. I did a paper on that several years ago, but don’t think I could locate it now.
Honestly, I don't know, but that would make a great story (and now you've piqued my interest in finding out). I got the phrase from this article - I've reproduced the relevant paragraph below.
Sunday was a day on which people were free from all but necessary work. Few were not associated with one or other of the local churches which both taught a system of received values and were community centres. A few saw Sabbath freedom as unnecessarily restrictive and in some cases it was. Presbyterians often forgot that John Knox had been a Sunday bowler. But few died or were maimed in weekend accidents.
