Or get it from Van Kampen’s book, The Rapture Question Answered

I don’t subscribe to that particular position, but they can post there, too, on the Rapture Caucus. It’s basically a “Rapture position” that is a separate event from the Second Coming of Christ to set up the Kingdom on this earth, at the end of the Tribulation (all three positions fit that designation...).
The book that I read, when it first came out was by Marvin Rosenthal — The Pre-Wrath Rapture of the Church, published by Thomas Nelson in 1990.
It was suggested by a Christian friend that I read it. He was sold on it, when he read it. But, I wasn’t even after reading it. I’m still pre-trib...
Pre-Wrath means, IMHO, the period of time just before God pours out His wrath on the unbelievers and the anti-Christ. He will take us out before that happens but just before. There are two book written on the subject that I’ve read, one is “The Sign” and the other is “The Pre-Wrath Rapture of the Church” by Marvin Rosenthal, a Jewish believer who always believed in Pre-Trib rapture until he started doing research for himself. When he changed his viewpoint, MANY Christians dropped him from speaking at their churches, etc. He paid a price.
