One poster here said...."The first person who formulated this eschatology was a Jesuit named Ribera in 1591AD. "
Is that true? Who knows but I supposed they could have connected the dots.
But the truth is the "rapture"...not called that in the earlier days was a well know theology.
Here is an article that tells us the truth...
You can read it in it's entirety here. ..
THE EARLY CHURCH
Since imminency is considered to be a crucial feature of pretribulationism by
scholars such as John Walvoord,1 it is significant that the Apostolic Fathers, though
posttribulational, at the same time just as clearly taught the pretribulational feature of
imminence. Since it was common in the early church to hold contradictory positions
without even an awareness of inconsistency, it would not be surprising to learn that
their era supports both views. Larry Crutchfield notes, “This belief in the imminent
return of Christ within the context of ongoing persecution has prompted us to broadly
label the views of the earliest fathers, 'imminent intratribulationism.’”2
Expressions of imminency abound in the Apostolic Fathers. Clement of Rome,
Ignatius of Antioch,
The Didache,
The Epistle of Barnabas, and
The Shepherd of Hermas all
speak of imminency.3 Furthermore,
The Shepherd of Hermas speaks of the
pretribulational concept of escaping the tribulation.
