'Raptus' is Jerome’s translation of the Koine Greek word harpazo, which means ‘caught up’ or ‘taken away.’
‘Harpazo’ is also used in Acts 8:39 where it describes the transporting of Philip suddenly from Gaza to Azotus.
Acts 8:39 'When they came up out of the water, the Spirit of the Lord suddenly took (harpazo) Philip away, and the eunuch did not see him again…'
Harpazo is used of Paul being caught up to the third heaven:
1 Cor 12:2 'I know a man in Christ who fourteen years ago was caught up (harpazo) to the third heaven.'
And again harpazo is used of the man-child being caught up to the throne of God:
Rev 12:5 '… And her child was snatched up (harpazo) to God and to his throne.'
In similar fashion, 1 Thess 4:17 tells us that we who are still alive at the time of Jesus’ coming will be “caught up” (harpazo) in the clouds to meet the Lord in the air.
