Well your religion did...It wrote the scriptures, didn't it???
Luk_24:44 And he said unto them, These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me.
Your religion wrote that Jesus claims the Old Testament consists of the law, the prophets and psalms...That's the canon of the Old Testament...
But wait a minute...There are no deuteralcomicals in there...They are not part of the O.T. at all...And they certainly were not recognized by any of Israel...The Catholic version of the bible that includes those funny books then must be a farce...Wouldn't you say???
(B) And if there was a final authority that the Protestant recognizes before the establishment of the canon, on what basis did that authority cease being final once the Bible’s canon was established?
You mean the Catholic canon, of course...The real canon and the authority didn't disappear in spite of the attempts by your religion to destroy it...There's only one place you get that...From the preserved words of God in the scriptures...
(C) And if there was no final authority before the canonical texts were put together then your Sola Scriptura must surely be fallible.
Oh we have a final authority...It's one you don't recognize...
Psa 12:6 The words of the LORD are pure words: as silver tried in a furnace of earth, purified seven times. Psa 12:7 Thou shalt keep them, O LORD, thou shalt preserve them from this generation for ever.
The Lord preserves his scripture...Those preserved words were being copied and passed around for 400 years before your religion got together to reject His words...
They don't teach you that in Catholic theology eh??? You don't get that with logic, common sense or philosophy...
All Bible Christians can do is throw bits and pieces of scripture and miss out on the coherent whole. If you cannot refute the undeniable fact, that even Luther admits, it is the Catholic Church that put together the canonical texts, there is no point in further discussion. For ELEVEN centuries it is the Catholic Church that assembled the canonical texts, interpreted its passages, and followed the rituals and traditions of the early Church and produced saints, martyrs, and stigmatists.
All this was under infallible Petrine authority. Deny Petrine authority and your Sola Scriptura collapses. Admit to it, and then you won’t be able to tell us at what point Petrine authority lost its Divine guidance. It did not because God gave to Peter and his Church the inerrant power to bind and loosen until the consummation of the world.
Not every grandmother, goose, gander and local foursquare church pastor in town or the likes of Jim Jones and David Koresh or and the Billy Grahams and Jeremiah Wrights can wave around their Bible books in the air and shout out their “own” interpretation. All this is worthless stuff that only shallow minds pick up. Go check your Black AME Churches, Jimmy Swaggart, Benny Hinn and the rest of charlatans who each proclaim their “own” interpretation of scripture and your own quoting of scripture does not have the infallible backing of Petrine authority You may deny it or admit to it, but either way the Sola Script game is over.
