Sorry, in advance for the rant....
As a Catholic, I agree.
To say the Catholic church has no authority to interpret the book it created seems a tad absurd. Anyone who uses the 27 books of the NT, is using an arguably Catholic document.
I mean if the head of Chrysler, wrote a book about the Chrysler corporation, OR the Auto Industry as a whole... and something in his book was being mis-interpreted, you THINK as the guy who made it.. he'd have SOME say in what he meant.
Now I KNOW the Catholic church didn't "write" the NT, but it did assemble it, pour over it, and use its link back to the Apostles to decide WHAT to include and more important what to exclude when it assembled the scriptures into the bible.
You'd THINK that mere fact would give it SOME street cred. -- but according to most Protestants.. that means the Catholic church is patently and categorically WRONG about the bible and how it should be interpreted. -- Which I gotta tell ya.. makes no sense to me.
Even Martin Luther believed this, that everyone owed the Catholic church some appreciation and authority, for giving us the bible.
I think this fact is made very obvious when later on in the Protestant Reformation, the Protestants sought to CHANGE the bible.. knowing it was a Catholic document. They changed the basis of the OT to differentiate THEIR bible from that of the Catholic church.. Without any unilateral agreement, council, or concensus, many began changeing the basis of the OT from the Septuagint, as it had always been, to the Tanakh. Creating in the process their own version of Scripture. They removed the 7 books of the Deutrocanonicals, which they now labeled the Apocrypha.
Seems obvious that they would have done this to move away from Catholic authority.
Martin Luther ALSO inserted the words "only" in to key scriptures to make it read as he KNEW it should have read.
Do those facts seem more like an authentic reformation or Heresy?
Changing scripture, using it and then attacking its creator, etc. Seems very disgenuine to me. Intellectually dishonest, and a bit like a heretic would act.
And then don't get me started on how this topic links in with Sola Scriptura doctrine... let's not go there... I'll rant for days.
