In this verse, St. Paul uses the verb ἁρπαγησόμεθα (harpagisometha), which means "caught up" or "taken away", with the connotation that this is a sudden event. The dictionary form of this Greek verb is harpazō (ἁρπάζω). The Latin Vulgate Bible translates the word ἁρπαγησόμεθα as rapiemur, from the Latin verb rapio meaning "to catch up" or "take away". It is from this that the word Rapture comes in it's theological context.
