The video is trying to tell us that historical Christianity has little to do with Jesus' teachings, that Christianity is in fact invented by Paul, a Roman citizen. I'm not sure how the author of the video fits emperor Augustus in. Since Augustus died in 14 AD, while Jesus was a teenager, I guess the author accuses August of founding the Roman Empire, which formed Paul into the fraudster he became, Paul who introduced the concept of submitting to the power of the state into the Bible. Since this is counter to God's teaching, this would make Christianity essentially a Satanic cult (at least in the author's opinion, since he refers to Paul as the Antichrist).
This is the part of the video I get. What I don't get is this: if the forces of evil managed to snuff out the original Christianity, as envisioned by Jesus, at such an early date, what makes the author think that the end world is coming just now? The author tries to make a connection between the Roman Empire and the United States, and their respective money, because Roman currency was probably the original sign of the beast, as envisioned by the author of the Apocalypse, the last book of the Bible. But during this whole period between Rome and the USA there were several empires which utterly dominated the world at their time, and each had its own "signs of the beast", and yet the world didn't end. Also the USA's been around for 237 years, and has been a significant power for over a 100 years, so why is it exactly this time that the world will end?
Judging by the author's denouncing of mainstream Christianity, of the state, and his/her belief that the Antichrist has already walked this world, which means we have been undergoing the Apocalypse for quite some time, I would guess that the author of the video is a Jehovah's witness. If not that, then just your common-variety freelance Bible "researcher".
