Catholics don’t abandon Sola Scriptura. In order to abandon a doctrine, we would have needed to hold it to begin with. I, for one, don’t believe that the early Christian Church held it, and thus, neither does the Catholic Church in the modern world.
Beyond this, from a Catholic standpoint, Sola Scriptura is a fiction. In order to abandon a doctrine, we would have to believe it really exists. Jim can claim that true Protestants hold to Sola Scriptura all he wants. Yet when I look out, I see a Protestant world so steeped in tradition that they can no longer even recognize it or distinguish it from what they believe the Bible says.
Apart from tradition, scripture doesn’t exist. People would feel this tension acutely, if we used language accurately (though this would be laborious). The words “scripture” and “Bible” are shorthand. Anyone who has studied textual criticism and the history of the canon knows that, when Jim says “Only one thing that really counts- the unwillingness of the Reformed/Protestant to abandon Scripture …”, what he really means is “Only one thing that really counts- the unwillingness of the Reformed/Protestant to abandon manuscript traditions of their traditional canon of Scripture ….”
I realize manuscript traditions are not usually what the Catholic Church means when speaking of Tradition. However, we can draw a point from this; No tradition – no Bible. Though not arriving at the statement from exactly the same direction, the following from Dei Verbum is still fitting in this discussion:
Sacred Tradition and Sacred Scripture, then, are bound closely together, and communicate one with the other. For both of them, flowing out from the same divine well-spring, come together in some fashion to form one thing, and move towards the same goal.
Scripture and Tradition “form one thing.” You can’t have one without the other.
You know I’m still your buddy, right Jim?
