Oh great...So really this post is about Romanism vs Protestantism?
Not necessarily. It is about authority, and who has authority, and who doesn't. At as you well know, it's not just Protestantism vs. Catholicism. Very often, it's also Protestants against each other. I've heard of the bitter rivalries between Calvinists and Arminians, between Lutherans and Calvinists, between Anabaptists, Seventh-Day Adventists, and other Christians. I have also heard the arguments between Mormonism, Jehovah's Witnesses, and other non-trinitarians and proper Christians. Truly this discord among Christians of all stripes is pandemic. So I would like to get to the bottom of it, and to the bottom of what the Christian faith, all modernisms, culturalisms, human preferences, and relativism aside, is. Every man, church, and group has a stake in this. The question is: what does it boil down to?
The Bible itself doesn't have the power to save. ...
Forgive me; who claimed this? It certainly was not I, nor anything like it.
There was no canon Bible as we know it when the Gospel message was first preached, and people still got saved. And often people who were the strongest adherent to the currently established scriptures of the time ended up missing the Gospel message completely.
There was an Old Testament, but not yet a written New Testament. That took a few decades to develop. Nonetheless, the Apostles and their disciples thought it important to write the Gospels, and the evangelists thought it important to write the Epistles and Saint John obviously thought it important to write down his Apocalypse (or Revelation). So Scripture is not a bad thing. It is the attitude with which it is received, among other things.
The Gospel that leads to salvation is simply that God loves us even though we sin and He sacrificed His Son to die for us to pay the necessary penalty for our sins so we can still enjoy a relationship with Him and the benefits of His love even though we're hopelessly sinful and don't deserve it, and all that's left to do on our part is to accept and believe in that to take our place in the Heavenly family. That's it, nothing else, even if we never look at a Bible after that.
I agree the Gospel can be summed up very succinctly, in many ways in fact, and does not need a whole book to describe it necessarily. That's often what the Apostles did.
That one thing is the thing that all believers have to adhere to to rightfully claim to be part of the body of Christ. Everything after that just pertains to how effectively and in what ways you're going to be able to live your life for the Lord while you remain here, and different people He may well equip in different ways and with different thought processes to achieve different purposes to reach absolutely everyone in this world that can be reached. Those differences do not affect salvation or membership in the body of Christ, though. Only whether or not you really believe that Jesus was the Son of God and died for your sins to save you.
Now, this is where I think we have a problem, if I understand you correctly. There is more to it than this simple Gospel. Jesus preached repentance surely. But He also preached obedience, and He preached certain things that we are to obey. The Epistles elaborate on this.
1 Corinthians and Galatians come to mind in this particular instance - the unity or discord of the Church. St. Paul saw both the Church in Corinth and the Church in Galatia end up becoming strongly divided into tiny sects. Both times he reprimanded the splintered churches, who obviously respected his authority. And then Saint Paul instructed the Early Churches as to the fine points these Churches were missing the mark on.
Does Christ, now, see the Church in its current state, as divided against itself, as the Churches of Corinth and Galatia were in the infancy of the Church? If Corinth was merely divided based on who baptised them (and they were divided based on
much more, if Paul's letter is to be any indication), how much more divided are we today?
As for by what authority do I base this on, I base it on the power of the Holy Spirit to give me the peace about it to not lie awake at night questioning whether or not I picked the right system of man to gain access to heaven.
Are your beliefs consistent with the Apostles? Are they consistent with the Epistles? Are they consistent with Christ and the Gospels? Are they consistent with the Church Christ established?
If you can answer all these questions with a sound and confident affirmative, I have nothing further to say to you as an individual, save that you should go in peace to love and serve the Lord, and that there's no such thing as learning too much about the Lord.
But if there is any strong disagreement between two people, or between two churches, who firmly believe they can answer all the above questions with a "yes", something is wrong. It is not the words of Christ, who said He is the Way, Truth, and Life. Nor is it the words of Paul, who affirms there is but one Gospel. Therefore, who else can it be but one or both of these churches, or people? And how can the Body of Christ be divided against itself and contradictory, and yet still be One undivided, united Body?

I am NOT trying to get everyone to think my way. If you will do the necessary research, I will, also. But I hate this discord between Christians.
Like for example, do we agree that all contraception is wrong? Or only that which is abortifacient? Or is contraception wrong at all?
Are or are not the deuterocanonical books Scripture?
Is the Bishop of Rome to Supreme Pontiff, or merely the first bishop among equals? Do bishops even have any authority? And what makes a man a bishop? Indeed, what is a bishop?
Does God predestine people to either salvation or damnation? Or are we completely free to choose?
Is God's grace irresistible or not?
Is John 6 to be taken literally or figuratively?
Is Genesis 1-3 to be taken literally or figuratively?
Are we to mission to Protestants? Are we to mission to Catholics? Are we even to mission to non-Christians?
These questions and many more are points of contention not only for different churches and different theologies, but also for different individual Christians. And I know it is an impossible task, but we must make an effort to dispel these contentions and think alike so that one may not be praising what is sinful, and another may not condemn what is righteous.
