Before giving an utterly direct answer, I must first take note of the basis on which it stands; your claim to a universally accepted canon prior to the reformation, something which cannot be demonstrated historically. The East and West have differing canons, even Catholics at the time of the reformation had differing opinions on canon to the modern CC; to quote Cardinal Cajetan, displaying a pre Trent wholly acceptable opinion of canon -
As such I don’t think the reforms are guided into a change that no one else adhered too, they stand with many noted Catholic scholars of their day.
I don’t think we can pick and choose to fit our ideology Lincs. I even have a problem with the RCC Canon because it doesn’t have all the books that Jesus and the Apostles used (The Septuagint). But I am just a man and while I am entitled to my opinion I am bound to Him and His Church.
The West made a decision with all their Bishops and the East made a decision with all their Bishops. They are both under Apostolic authority and succession.
Now if Luther included the RCC Canon in his German translation and the original KJV also included it, who and why a different Canon was decided. Protestant translations claim that the Bible is the Inerrant Word of God.
I am compelled to press the issue brother,
How did the Holy Spirit help the Protestant Canon?
Why did the East and the West have the wrong Canon?
How did the Church founded by Jesus use the wrong Canon for over 1000 years?
I would refer to Institutes, book 4th, chapters 11 & 12 for a detailed explanation of it, as it encompasses a lot -

It covers church disciplne for me, the power to proclaim ones sins forgiven upon repentance, and not forgiven to the unrepentant… But please see the link for a more ‘authoritiative’ view on it than my own
Lincs, I have to say that while I didn’t meet Calvin, you seem to be a far better person and probably much more pleasant to talk to

.
So Calvin had more Grace in interpreting how the binding and loosing applies than what all the Bishops of the Church agree and practice?
I have to ask again,
How did the Church get it wrong for so many years?
I hear so many Protestants criticize the RCC and the Pope and how it is all controlled by just one man. Do you know that the Church meets with their Cardinals and Bishops? That most decisions are made by a group of men (A really big group) and not just one man?
And here we have one man explaining his opinions (which I have no problem with) but while expressing his opinions, he dares say that all other opinions are wrong!? Under what authority can he establish this alone?
Can anyone grab a Bible and claim authority under God and the Apostles teachings and say that they now have the authority to bind and loose on earth?
Sorry for the late reply but I will be testing on a work certification this Wednesday, and speaking of which I need to study more

May His Peace be with you,
Jose
