Q: Which religion thinks the Book of Revelation already happened?
A: There’s no doubt that many of the events described in Revelation have already happened. Any history book can verify that for you.
This is not to say that multiple or additional fulfillments are not possible.
For those who believe the book is literal … if that is so, then it is obviously impossible for anyone to correctly interpret.
Proof for that can be found in many of the Protestant denominations, which have been predicting the end for generations … with consistent, zero percent accuracy.
Only God knows the way things will actually wrap up … and if he wanted us to know, he wouldn’t have given us a book that nobody has yet successfully understood.
The parallels between the Book of Exodus and the Book of Revelation, the Pharaoh of Exodus and Anti-Christ of Revelation, Moses’ plagues and Revelation’s Great Tribulation, are hard to miss.
Study both books and see what you can make of it.
One thing’s for sure though.
The “end” of the Jewish “world” happened at the hands of the Romans in 70 AD, just as Jesus predicted.
The “end” of the Roman “world” happened about 400 years later, at the hands of the Barbarians, which handily fulfilled other, less concrete predictions, and which also left the Catholic Church as the only remaining, effective world government … for the next thousand years.
If and when there’s another major event like either of the above, it will be one heck of a mess, and it will likely occur with little warning, so everybody better remain prepared, come what may.
And the only sure way to do that is through consistent, faithful, and charitable participation in all of the work, worship, sacraments, and devotions of the Catholic Church … which is the only church that Jesus Christ ever founded, authorized, empowered, and eternally guaranteed, for the purpose of our salvation.
