There are sincere believers who believe that the "Last Trumpet” which shall call up the true Church to meet the Lord in the air is the trumpet of Revelation ch.1 1: 15. "The 7th angel sounded and there were great voices in heaven, saying, the kingdoms of this world are become the kingdoms of our Lord, and of His Christ; and He shall reign for ever and ever”. They confuse this trumpet with the trumpet of 1st Corinthians ch.15:52, "In a moment, in a twinkling of an eye, at the last trumpet: for the trumpet shall sound and the dead shall be raised incorruptible, and we shall be changed”. There are no sufficient grounds for supposing that there is any link between these two Scriptures The trumpet of Revelation 11:15 is an ’Apocalyptic’ trumpet and some believers believe, therefore, that the Church, will continue on earth until midway through the 7 years of the Great Tribulation which is still to come. The trumpets of Revelation herald only judgments.

When Paul spoke of the last trumpet in 1 Cor. 15:52 he could not expect his readers to equate this with the trumpets of Revelation ch.1 1 as the book of the Revelation had not been written by this time. It would be at least 40 years on from the time Paul wrote 1st Thessalonians which also relates to the Rapture and the Resurrection of the true Church as does 1st Cor. 15. Paul could not have known the Revelation would be written, neither his readers at that time, even though the Holy Spirit is the author of the whole inspired Word of God.
