The Gnostics (unknown, but quite POSSIBLY the earliest sect of Christianity after Jesus) and the Cathars (revival of Gnosticism in 1200s, violently wiped out by the RC) seemed to think so.
Remember, they are the ones regarded as heretics. Back in those times (Cathars) the Roman Catholic church was a MASSIVE political propaganda machine, well oiled, in convincing everyone who the enemy is (not them of course). And much of that propaganda has survived forever. There is a lot of violence associated with the RC Church history. Good violence? Or is all callous ruthless, burning people at the stake violence, evil?
It makes you wonder whether, regardless of what sect of Christianity we believe we come from, we all see the Bible according to the RC church, but just not their particular EXTENSIONS of it (their Gospel)
Who put the Bible together in the order that it is today, in the way they wanted you to see it? In the way that they wanted you to regard anything else as heresy? The RC church...
So however you think about the Bible, you are following the RC version of what is truth, and disregarding anything else (like you can't think for yourself or discern falsity yourself)- according to your belief in the RC Church being right about everything to do with what IS inspired by God, and what IS NOT.
In a way, regardless of what your Gospel is, it is rooted in the Roman Catholic church, because it is based on their version of truth, that you get that Gospel from.
