Tricksy.
The OT Canon is not a matter of divine revelation but of church competence.
The Jewish community would disagree with your opinion, not to mention the prophets of the old testament, And How do you explain Jesus fulfilling the Old testament divine law, and Prophecies revealed by God himself through his prophets? Maybe Moses could help you believe the Old testament was a divine revelation, Moses convinced Pharoah of Egypt by God’s revelation, I am sure you have heard of the 10 plagues and the parting of the red sea?.
The OT Canon Luther preferred was not one which he made up himself. It was the one preferred by Jerome and many before him.
St. Jerome who translated the Vulgate bible? is this the same St. Jerome who was a Roman Catholic, that you have been badly informed of?. Luther was many centuries after St. Jerome, and Luther agreed with St. Jerome to remove the 7 books in question. The difference between these two Roman Catholics, one became a Saint because even though St. Jerome wanted the 7 books taken out, St. Jerome obeyed the authority of the Pope,To keep them in the bible because our dear Lord Jesus quoted from these; while Luther protested the authority and Chair of St. Peter.(Pope) and invented his own doctrine and removed 7 already canonized books of the bible. God said we are not supposed to remove or add to his word, Luther in his free will did what he wanted to, and so do the other over thousands of denominations.
At the time that Luther was living and working, Catholic Scholars (and Luther was a Doctor of Sacred Scripture) were permitted to have divergent opinions on the matter and at the time many were actually doing so (Erasmus and Ximines come to mind).
I agree with you, all the Roman Catholic saints,and bishops, argued, and had diversed opinions, But when their opinions and freewill thinking contradicted the Apostles Traditional teachings, and Jesus Gospels. The Pope and the Roman Catholic councils settled the matter, not the individual free thinker.
Another thing to consider is that, at the time, no one really made a big deal out of it. There were plenty of issues to take Luther to task for but his ordering of the OT Canon was not one of them. There wasn’t a peep out of his Catholic antagonists.
**Are you reading the same history that is recorded, or has some one distorted the facts to you? **
As for Matthew 16:18: Most Protestants understand it to refer to Peter’s confession, that confession being the rock upon which the church is built, here identified with Peter’s person while Catholics say it refers solely to his person and indicates Peter’s personal authority in the church which is a bit circular.
** What you are confusing here is when Jesus renames Simon Peter, and when Jesus gives Peter (singularly) the keys to the kingdom of heaven, and what ever Peter bound on earth Jesus will bound in heaven, vice versa. So we have the first Pope possessing the faith, and the authority given to him by the Father in heaven, and the keys by Jesus himself, any other question? BTW, Catholics believe Jesus renames simon Peter after the heavenly Father revealed this to him (Peter) And his confession of faith, Jesus will build his Church, and also Jesus gives Peter the keys to the kingdom of God. This is believed for 2000 years, where have you been?**
In any event, even if the Catholic view is correct, there is nothing here which would necessitate an enduring “charism” successively preserved and continued in his successors, or even more particularly that it has anything to do with the church’s competence to recognize and bind the Scriptural canon.
** So then you are calling Jesus a liar, because he promised to be with his church for all ages? You disagree with the Holy Spirit, when he confirms the successors of the apostles, beginning in the book of acts? It is through the Holy Spirit that Jesus promise his church who would come after him, and reveal , and speak for them in all Truth, the bible was canonized by the Roman Catholic church under the authority of Jesus promise the Holy Spirit.**
So you see, it is a matter of interpretation.
