The catching away of believers before the time of great tribulation was taught by Ephraim the Syrian who said in his book, Antichrist and the End of the World published in 376. He wrote, "Because all Saints and the elect of the Lord are gathered together before the Tribulation which is about to come and are taken to the Lord in order that they may not see at anytime the confusion that overwhelms the world because of our sins."
Also note the words of Joseph Mede, "I will add this more, namely, what may be conceived to be the cause of this RAPTURE of the saints on high to meet the Lord in the clouds, rather than to wait his coming to earth....What if it be, that they may be PRESERVED during the Conflagration of the earth and the works thereof, 2 Pet.3:10, that as Noah and his family were preserved from the Deluge by being lift up above the waters in the Ark; so should the saints at the Conflagration be lift up in the clouds unto their Ark, Christ, to be preserved there from the deluge of fire, wherein the wicked shall be consumed?" ("The Works of Joseph Mede," 1672, London edition, Book IV, p.776)
So a one odd bod, Ephraim, taught that, does that mean it should be a teaching of the church? Mede's writing was nothing like modern dispensationalism. It does agree, I think with Matthew 13:30 At the time of he harvest.the tares would be burnt, and good grain harvested. Saints will be raised on the last day, John 6:40, 39,44,54. John 11:24. It will also be he day of judgment. John 12:48.
