I think it's almost inevitable that guidance would be taken from additional sources. When someone claims they "just read the Bible", look closely. Usually, they're just unaware of their own presuppositions, and are unable to examine them.
I’m ready for something deeper and am thinking of Jeff Cavins or Scott Hahn or Ignatius. Tax-chick — any experience with any of those?
My understanding is Scott Hahn has done some writing in covenant theology, that (from the excerpted quotes I saw) looked interesting. Reformed protestant theology is thick with it. (See the link in my post earlier in this thread.) I've got no idea how that would integrate into an RCC worldview.
Scott Hahn writes a lot about covenant theology. Try “A Father Who Keeps His Promises” for an overview; this is a high-school level text, iirc, but gives an idea of what to expect from some of his other work.
I have the Navarre Bible commentaries. This set has the RSV text (English) and the New Vulgate (Latin), with commentaries that include simple historical explication, quotations from the Fathers, and modern European theologians.
The “New Advent” website has a substantial amount of early writings available online, iirc. If you want to read St. John Chrysostom’s sermons on the Gospel of Matthew, for example, they can be found there.
You've heard of the new Catholic student drinking game? You open any book by Hahn, and every time you see the word "covenant" you drink a shot.
Many think the game is a bad idea because, like the previous one which was based on lousy puns, it leads too quickly to perilously high blood alcohol levels.
JUST KIDDING!
