Your fictional "dead Anabaptists" have nothing to do with the origin of scripture and the fact that it was the Catholic Church that preserved it, translated it, and declared it divinely inspired.
You don't have to be catholic to see this...all you have to do is study history.
Sorry, but I don't worship people and organizations because of what they do. I worship God because of who He is.
The fact is that the Catholic Church has played a role in God's plan. It is not the Catholic Church's plan. God's plan would still go on without the Catholic Church.
If you really care about history, you will look back to the 4th Pope and the letter that he wrote to the Church of Corinth. That's where this whole mess began.
The Church of Corinth was not under Rome's rule, and yet the head of the Church of Rome wrote them a letter. When no one condemned him for writing a letter, future generations of Pope took this as the power and right to give orders and make decisions. There begins the layer upon layer. The searching for justification that Rome is supreme. Later they included Catholic into the name of the Church of Rome because they were so full of themselves. And the funniest thing is it all started with a letter that no one asked for and no one rebuked.
And if you even bother to read the letter, you will notice the opening statement "The Church of God which sojourns at Rome, to the Church of God sojourning at Corinth"
This Pope considered the churches to be seperate. He considered the churches as belonging to God. Now contrast that to the modern RCC's view that all churches and Bibles exist because of the Roman Catholic Church. Just a bit different don't you think?
