If so, where do you find the statement in the Bible saying this? We know Jesus made no such statement in Matt. 24, where did Paul say such? Though Paul spoke of the catching away (the rapture)in 1 Thess. 4, he said nothing about this being before the tribulation, nor there being two events, a two stage affair.
Inferences are not sufficient for something as important as this, we need a clear statement somewhere using the language you used, "the rapture is one event, the 2nd coming is a distinctly separate event.
Romans 5:9 is a clear statement that the Church will not go through the Great Tribulation.
I'm not trying to put you off, I want you to see it for yourself.
Rev. 19...Rev 19 takes place during the Tribulation...The church (the Bride) is in heaven getting married...
The church goes up...The Wedding takes place...Jesus and the Bride return at the 2nd coming...
