I have been studying eschatology pretty seriously for two decades. I've come to the conclusion that if a person doesn't understand prophecy, the age of grace, the pre trib rapture, etc, then that person is almost always indoctrinated with Catholic ideas.....either from the RCC itself, or, from one of the many denominations that held onto made up Catholic ideas and teaching.

The RCC is the Woman that rides the Beast, 100%.

Anyway. My personal opinion is that the life of this planet will be 7000 years total. 4000 from creation to Jesus's birth, death and resurrection. There will be 2000 years from His ascension into heaven until His second coming. Most scholars believe he was crucified and resurrected in 33AD. I believe His return at the end of the Tribulation will be around 2033. Take seven years off for the Trib, that is around 2026 for the Rapture. It COULD be earlier, given that there may be a gap year or two between the rapture and beginning of the Trib. But IMO, we have a few years left.

After the Trib, the 1000 year Millennium starts.
