Paul is describing the Second Coming on the Last Day, and is assuring his readers that they will in no way be "left out" or "left behind" if that should occur while they are still alive. That's all. No "secret rapture" needed or taught.
Go back and reread what I posted.
I never said anything about a secret rapture.
My postings are, for those who argue, there is no rapture, or that the word rapture doesn’t appear in the Bible. The word rapture IS in the Bible, just not in the English Bible. And the rapture is specifically mentioned in 1 Thess. All that’s left to discuss is the timing.
