The Bible did not originate with the Romish church. But I realise that is something many people hear all the time until they accept it as unquestioned truth.
In regard to the Vat of sin being satanic, it could take many, many posts to cover, especially in detail... plus it is late where I am as of this posting, so I will just mention a couple of broad, general things first.
Number 1: Pagan, blasphemous doctrines which mock God and His plan of salvation. And not only that, but also naturally affects mankind in the negative sense, as it alienates him further from God and closer to the father of lies.
Number 2: As if the first broad stroke was not enough, this must be included. The evil history of the CC which anyone can now examine, and their boasting about how they (the RCC) never change... (The office of the 'holy' inquisition was never done away with, but merely had a name change)
Satanism has been recently exposed as being practiced within the Vat-of-sin as well. The very titles that the Pope has are an insult to God, for example, holy father... that title belongs to God alone. But oh no.. the Pope believes himself to be God on earth. There are many things that they believe and practice, but this stuff is very rarely spoken by them to the general public. And I suppose I'll throw in the harlot of Revelation 17 as identifying the Roman church too.
That should be enough for this post. Perhaps I should help expose them in other, more relevant threads? Hmmm...
