Absolutely ridiculous statement. The Old Testament had been existence for some time. Or don't the Catholics consider that the Bible?
Not to mention that the New Testament scriptures were also voraciously read and taught from...they just hadn't been collated yet.
"they just hadn't been collated yet"
Where did the table of contents of the Bible come from? How do you know which, if any, books belong in the Bible? Because Martin Luther says so?
Us Protestants should keep our distance from Catholicism. While many Catholics are fine, upstanding people (and they have done a excellent job opposing abortion), the Roman Sect is ridden with liberal heresies.
The canon wasn't closed until after 400. And, BTW, Catholics and Orthodox use all the books that the Jews use - including the ones that Luther removed.
