Nevertheless, the word “RAPTURE” is not in the Bible.
Regarding the word "rapture":
Greek
The 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 harpazō (ἁρπάζω).[15] This use is also seen in such texts as Acts 8:39, 2Corinthians 12:2-4 and Revelation 12:5.
Latin
The Latin Vulgate translates the Greek ἁρπαγησόμεθα as rapiemur,[16] from the verb rapio meaning "to catch up" or "take away". (http://en.wikipedia.org/wiki/Rapture)
So, YES the term IS used in Scripture in several places as the "catching away", "caught up", "snatched away", are all phrases used IN Scripture referring to the time when Christ shall descend from heaven and "rapture" those who are His.
Neither is the word Pope, Transubstantiation, vicar, Catholic, and many other words Christians use today. I surely hope you didnt think that reply was going to increase my impression of your knowledge of scripture or adherence to it.
