If you could imagine that Christianity would have a proper and realistic way to come together and protect the doctrine which they already believe, then what would it be?
Let's say that Christianity as a whole believed that marriage is between one man and one woman, but it had never been defined in such a way that it was binding on the faithful to believe (essential belief). And then some issue arose where some yahoos started saying that so-called "gay marriage" is just fine and starting to be a place where the faithful could come if they wanted to accept that strange idea and so justify their own false belief.
What would be your solution?
I don't see it as possible in Protestantism. There is no one voice which is the authoritative final answer for Protestants. And even councils of Churches in Protestantism are led astray by false doctrine, and many Protestants reject their conclusions. And gay marriage isn't covered in the Bible, at least, it isn't directly condemned.
Why would you bind (force) anyone to believe what you say? Even if you enforce it on them, they still don't believe in their heart.
The RCC makes the false assumption that following pre-described doctrine equals believe. That is not the case.
All Christians are bound by God to believe the Truth, and if the Truth is known with certainty, then by God they are bound to believe it, and by it they will be judged.
The RCC also teaches that divorce is evil, yet so many Catholics divorce anyway
So what good does "binding people" do if they don't practice it anyway?
How many Catholics do you think there are who use birth control even though the church "binds" them to not use them?
What good it does is provide them a stronger reason to understand that they need to repent of their evil deeds and believe the Gospel.
You talk about the Pope not being like a typical dictator.
Yet the RCC as a community of believers enforces people to believe exactly the way she describes and if they don't they are declared anathema.
How is that not dictatorial? How could you call such a thing "unity"?
I see now that you are not even going to try to work out problems in Protestantism in this post. Why not? Are they impossible?
There is plenty of room for opinion in the Catholic Church. The things the Church defines for believe are just the most important things, the truths of the faith that are delivered from the apostles. There is plenty of room for discussion on many theological issues.
A person separates himself from the Church if he denies
the truths of the faith, not if a person perhaps is ignorant (and so doesn't know to believe. That is what truth does, it divides, and that is why anathema is in accord with the nature of Jesus himself, and the Catholic Church's practice in that regard is actually just like Jesus himself.
Yes we could all come together under the umbrella of the Catholic Church and pretend we are one big happy family following the teaching of the Church.
Or all the Catholics could come together under the umbrella of the Protestant Church and pretend to do the same.
Would that make you feel better because you now have a (false) sense of unity?
There is no defined truth in the so-called Protestant Church. It is a loose association of people with various conflicting ideas of what the truth is, derived by fallible men from scripture in various ways. "Pretend to be united" is exactly what Protestants have
to do. Catholics actually have a path to get there, which is a defined set of doctrines with regard to faith and morals. That some people dissent is just a sign that they divide themselves from the teachings of Christ, not that the Catholic Church is divided.
Believe me, we are fully aware that there are many Catholics who refuse to accept the teachings of the Church. This is a grave matter which we try to address, and a danger to their salvation.
Yes, God wants you to make up your own mind and not have your mind made up for you.
Yes, he wants us to align our own hearts to the Truth that he revealed and preserves in the Catholic Church, and not make up our own version of it all.
The Bible teaches that each and every one of us has to work out his own salvation.
"Do not put your trust in princes, in human beings, who cannot save."
My solution for the vast majority of the Catholics is for once pick up a Bible and start reading.
Then test what you are being told by your Church to what you read in the Bible...then make up your mind.
BTW: Protestants are of course not excluded from this exercise.
I have read the Bible, studied the Bible, listened to the entire Bible through once and again another half time, and it only solidified my belief that everything that the Catholic Church teaches is true.
