I on the other hand, have no problem with the doctrine..in fact, I endorse it. I am willing to discuss the term, so long as we can remain polite and civil.
Yes, some used the English word "rapture" to describe the event (Irving, LaCunza, MacDonald and of course, Darby) . However , this is just the English rendering of the Greek, Harpazo (snatching or gathering up) or Parousia (presence or arrival).
First off, the word "rapture' is not found in the Bible..but then again, neither are the words "trinity", "discipleship", "theocracy" or "missionary" found in the Bible, but that doesn't mean they don't exist or are not factual.
..And of course the English word "rapture' covers both Jesus' arrival and His gathering up of the saints, to take them away, avoiding the extreme tribulation.
"..And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened." (Matt 24:22) The very act of Jesus coming for his own, is well outlined in (1Thess 4:14-18);
14 For if we believe that Jesus died and rose again, even so God will bring with Him those who sleep in Jesus. 15 For this we say to you by the word of the Lord, that we who are alive and remain until the coming of the Lord will by no means precede those who are asleep. 16 For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God. And the dead in Christ will rise first. 17 Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord. 18 Therefore comfort one another with these words. The rapture (harpazo or parousia) was a doctrine in the very early church..

Many of the Christian Universities endorse the theory..including such as Liberty U. and many others.
Here, one of the great contemporary preachers of today, Dr David Jeremiah, explains the "rapture".. grab your Bible and prepare to give him a bit of your time, checking him against your Bible.
