Pre-Wrathers and many others with mistaken views need to claim that the Trumpets are all God's Wrath insist that in Revelation 11 when the Elders and the Four Cherubim say "and thy wrath is come". That the Greek should be translated "has come" or "has already come".
My argument however is it simply doesn't matter how past tense the grammar is. Everything here is in reference only to the Seventh Trumpet and what happens immediately after it's sounded. Nothing said here was true before the Seventh Trumpet.
"And the nations were angry, and thy wrath is come, and the time of the dead,
that they should be judged, and that thou shouldest give reward unto thy
servants the prophets, and to the saints, and them that fear thy name, small and
great; and shouldest destroy them which destroy the earth."
How much of that was already happening during the earlier Trumpets? Wrath is the only one anyone would even try to argue for.
Trumpets Biblically are warnings, the Last Trumpet is the Last Warning, that's when the Parousia happens and the Day of The LORD begins.
The fact is, Wrath has already come at the Seventh Trumpet, but it would be inaccurate to say that before the Seventh Trumpet.
That the Bowls are described as "finishing" or "completing" God's Wrath is seen as evidence God's Wrath begins sooner. Fine, it begins with the 7th Trumpet and is finished by the Bowls.
