The Last Trumpet is Paul's phrase in 1 Corinthians 15:52: in a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed. 1 Thessalonians 4:16 calls it the trump of God at the descent. Whether the same trumpet as Revelation 11:15's seventh trumpet (some affirm, some deny), it signals the resurrection of the saints at Christ's return.
(1 Cor 15:52; 1 Thess 4:16.) The trumpet sounding at Christ's return, signaling the resurrection.
Old Testament background: trumpets summoned Israel to assembly, war, festivals, and theophanic events (Sinai, Ex 19:16-19). The eschatological trumpet inherits and consummates the symbol.
New Testament references: 1 Cor 15:52, 1 Thess 4:16 (the trump of God at the descent), Rev 11:15 (seventh trumpet, possibly the same), Mt 24:31 (Christ's elect gathered at His return with a great sound of a trumpet).
1 Corinthians 15:52 — "In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed."
1 Thessalonians 4:16 — "For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God."
Matthew 24:31 — "And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect."
Revelation 11:15 — "And the seventh 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."
Modern Christianity often spiritualizes the Last Trumpet; the Pauline picture is acoustic, public, and decisive.
The trumpet is loud. The dead hear it (Jn 5:28). The living are changed in the twinkling of an eye. There is no quiet escape; the New Testament resurrection is announced by acoustic signal, witnessed by every ear.
The household's appreciation of this image deepens its hope. Death is real; the trumpet is louder; Christ's call is final. Decay does not have the last word; the trumpet does.
Greek salpinx (trumpet) and salpizô (to sound).
