The Day of Shouting or Blowing of the Trumpet
The ‘Last Trump’ of New Testament eschatology refers to the last of a traditional 100-blasts of the trumpet blown on this day of Yom Teru’ah. [The less-commonly held belief that the ‘Last Trump’ is a reference to the seventh and final Trumpet of the Apocalypse seems less credible.]
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 Cor 15:52
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: — 1 Thes 4:16
Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light. —Ephesians 5:14
These verses suggest a link to the unanimously misunderstood ‘rapture’ of the church. Yes, the rapture is a real event. But it represents a spiritual transmigration (most likely at a point of psychological extremis), rather than a fleshly teleportation that so many Christians—incredulously—anticipate. It is a metaphysical, not a physical, event.
Finally, we do well to recall that Yom Teruah is the only moadim (appointment) with YHWH that falls on the first of the month (Rosh Chodesh). As such, its timing based on the siting of the first sliver of the new moon. This was historically—and rather pragmatically—celebrated on both the first and second days (known colloquially by the Hebraism ‘One Long Day’) of the seventh month. A technicality that gave Yom Teruah the pseudonym “The Day That No-One Knows“, yet another Hebraism that Yahuwshuwa did allude to (Matthew 24:36-37) and a source of much angst for the self-confessed, but not born-again, Christian.
