Standing applause.
You have hit the nail square on the Protestant thumb.
About the only thing that I can add is that the Church chose Scripture to begin with - the choice of the OT (Septuagint) and the NT rests with the Church - guided by the Holy Spirit, not any Tom, Dick or Luther regardless of how infallible they deem themselves.
And just think of the books that were thought of as Scripture - we know of about 80 Gospels or so - and which versions of each book were to be chosen? Each book had to be hand copied - and the copyists were not always the most faithful to the originals.
There are many out there that believe that Jesus carried a KJV (1611 of course) around with Him and taught in English. I have run into a few and have done my best to disabuse them of that notion (if English was good enough for Jesus, then it is good enough for immigrants - so I have been told).
I had a friend in high school (mid-1960's) whose very aging French great-grandfather came to the US for an extended stay. Even though the old guy was a devout Catholic he refused to attend Mass in the US because he said that God only choose Latin to speak to man.
