The rapture is an eschatological concept of a minority of Christians, particularly within branches of American evangelicalism, consisting of an end-time event when all Christian believers who are alive, along with resurrected believers, will rise “in the clouds, to meet the Lord in the air.”
Koine Greek of 1 Thessalonians 4:17 uses the verb form ἁρπαγησόμεθα (harpagisometha), which means “we shall be caught up” or “taken away”, with the connotation that this is a sudden event. The dictionary form of this Greek verb is harpatsō (ἁρπάζω). This use is also seen in such texts as Acts 8:39, 2 Corinthians 12:2-4 and Revelation 12:5.
There are also differing views among Christians regarding the aerial gathering described in 1 Thessalonians 4. The majority of Christian mainline churches do not subscribe to pre-tribulational views.
Catholics, Eastern Orthodox, Anglicans, Episcopalians, Lutherans, Presbyterians, United Methodists, the United Church of Christ and most Reformed Christians do not generally use rapture as a specific theological term, nor do they generally subscribe to the premillennial dispensational views associated with its use. Instead these groups typically interpret rapture in the sense of the elect gathering with Christ in Heaven after His second coming and reject the idea that a large segment of humanity will be left behind on earth for an extended tribulation period after the events of 1 Thessalonians 4:17.
