But before that, there was no central authority, but Christianity was a religion of just only the common folk mainly, etc.
The problem during the first, second, and third centuries, is that this new religion of the common folk was spreading like a wildfire, etc, and Rome tried very, very hard to eliminate it during the first, second, and third centuries, but eventually saw that they couldn't do it eventually, etc.
So the Roman emperor Constantine eventually decided to incorporate it into Rome as the religion of Rome eventually during the fourth century, and so the RCC was born or was created/made during that time eventually, etc.
And the rest is history really, but before that there were no Catholics, or Catholic Church, but the religion was just only a religion of the common folk mainly, with no centralized authority.
So the RCC succeeded in removing the scriptures from the common folk eventually, which is when they started to become very, very corrupt after that. Not every believing Catholic became this way, but just the centralized authority, etc.
And later, when they saw that the religion was about to be given back to the common folk again, they saw it as a very, very great threat to their authority (again), etc.
And I say "again", because that's always what happens with this specific religion of believers in Jesus Christ, or followers of Jesus Christ, or followers of "The Way", or this new religion called Christianity always, etc.
Every authority that seeks to oppress always knows that they have to do something with this religion called Christianity before they can do that first, and that still holds true today, etc. It's always a threat to any establishment that seeks to oppress always, etc.
Like I said, they might use new and different methods today, and also like I said, they've learned that they don't necessarily have to get rid of the text anymore now today, but they always know they have to do something about this first before they can do what they want to do always, etc.
Rome had to learn that a very, very long time ago already the hard way, which is why back then, they eventually decided to adopt it as their state religion, and formed the RCC, etc.
God Bless.
