The Catholic church may well be the one that out of it comesv forth the Antichrist, bugt here's the interesting commonality between all three theories:
They have the very same narrative, in not just the fact that they're enitities out to covertly conquer the world, but have essentially the same means in how to do that: through chaus, plagues, famine, wars, assassinations, etc; then the hijacking of key positions in governments, and institutions of power.
Isn't that a bit odd to you?
Then there are oither conspiracy theories, such as the UFO Conspiracy, Flat-Earth Conspiracy, each one has a unique narrative but runs on the same, shadowy entity large enough to infiltrate nearly every major government in this world, and yet, there are absolutely no loose lip, or paper trails behind.
Not even the very best of intelligence agencies could match their skills in relations to covert operations. Why, because in comparison to such specific agency (i.e: CIA, Shin Bet, etc), they're an extremely large group. After all, how else are they able to span the globe with their "tentacles" in every government and banks? The bigger they are, the greater the chance of compromise.
You could say that the Devil gave them power to overcoime their human weaknesses, but this how I feel about it with the following meme:
