I don't know about that, Clay...I read scripture at home, I know lots of people who do. And, of course, we're encouraged to look up the readings for Sunday Mass and spend time reflecting on them before going to church. Then there's the Rosary which is entirely bible based, and the Liturgy of the Hours which relies heavily on the Psalms, to name a few. There are also plenty of bible study groups in the Church.
Of course, you're correct in that Christ founded a church, not a bible, and 'bible only' is a relatively recent man-made addition.
I think there is one thing which is most misunderstood, by non-Catholics, as well as Catholics....That the Mass is actively participated in by the laity. And it is taught to be actively participated in....
Especially non-Catholics have the view that everything comes down from a hierarchy, and this makes the laity some sort of mindless zombie, just following orders.
I think there is evidence within the walls of every church that there are persons, in there, as a habit, or a tradition, but this has been on the decline. And that is a good thing. Get rid of the dead weight. Get back to the basics, live and teach them.
The first half of the Mass, the Gathering in to Hear the Word(Bible) is where one actively participates with the mind and heart, as much as the Feast and the Going Forth....
