I just looked up I Thess 4 up in 14 English translations and they are nearly exactly the same.No, you are confused. Paul does not teach a rapture, look your 1 Thes text up in Greek.
1 Thessalonians 4:16-17 (NKJV)
[sup]16 [/sup]For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God. And the dead in Christ will rise first. [sup]17 [/sup]Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord.
