The word comes from a Latin translation of the Bible from about AD 400 called The Vulgate. The Vulgate uses the Latin word rapturo to translate the Greek word harpazo in 1 Thessalonians 4:17.
Starting sometime in the late 1800’s, Bible teachers began using the word to describe the event Paul wrote about in 1 Thessalonians 4:13-18 as well as in 1 Corinthians 15:50-56 and Philippians 3:20-21. These students of Scripture chose a word, based on the ancient Latin translation of the Bible, to describe the event that the apostle wrote about in these texts and referred to in many other passages.
The rapture is the of Titus 2:11-14; it’s the means of our deliverance from the day of the Lord wrath as the Lord promises us in 1 Thessalonians 1:9-10 and 5:1-10.
