Since we are talking Mass according to the Missal of John XXIII ia it really correct to call it "The Tridentine " Mass? By the time of John XXIII the Mass of Pius V had already undergone a number of revisions, slight as they might have been. I was around for quite a while before Vatican II, served Mass from 3rd Grade through College. I graduated before Vatican II and I cannot recall ever hearing it called the Tridentine Mass until fairly recently. It was just Mass before and still just Mass afterwward for most people.
As far as Catholics reading Catholic Books, my Mother had only a Bible, Extension Magazine, Our Sunday Visitor ( 5 cents after Mass just outside the Church Door) and a few pamphlets from the rack in Church. No books. At graduation from College I had a book on Intro to St. Thomas, a Sunday Missal, A text on the Virtues and Moral Theology, some class notes on Canon Law of Marriage and Sacred Scripture ( a class in which we never cracked a Bible.) and that was pretty much it till Vatican II stirred up what I probably saw as a “sleeping Church.” Now I have four or five four foot bookshelves crammed with lots of stuff and our Church has maybe half again as many in its library. Some people are reading, but most working Mothers and Fathers don’t really have the time and maybe not the inclination. I doubt if any of my six children have even a half dozen Church related books. They range in age from 32 to 46 and have some interest, but it doesn’t burn in their soul like mine seems to.
