The "Rapture" of the Church is described in
1 Thessalonians 4:16-17.
         "For the Lord Himself shall descend from Heaven with a shout, with the voice of the archangel, and with the trump of God; and the dead in Christ shall rise first: then we which are alive and remain shall be caught up together with in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord."
