The great judgments of the Tribulation consist of seven seals, which were attached to the "title deed" to the earth. In that deed, which only the Lamb is found worthy to open, are all the events that would transpire before God brings history to a close with His destruction of the old heavens and earth and the creation of the new heavens and the new earth. Within the seventh seal are the judgments of both the seven trumpets and the seven bowls, with the judgments of the seven bowls coming after the seventh angel sounds the seventh trumpet.
In other words, you have
- one scroll
- seven seals, which seal up all the judgments of the entire Tribulation period
- the seventh seal consists of the judgments of the seven trumpets, followed by the judgments of the seven bowls
- the seventh trumpet signals the pouring out of the first bowl, which is followed by the pouring out of the second-through-the-seventh bowls
How best to collocate just the judgments of the seven trumpets and what transpires after each successive trumpet is sounded (or blown) is a little tricky, especially since the seventh trumpet is not a judgment, per se, but rather it announces seven subsequent judgments which in turn usher in the denouement.
Compounding the difficulty is that within "Christian eschatology," as you put it, there are probably a dozen or more mutually-exclusive ways of looking at the ordering of the events and chronology of the Great Tribulation. Some Christians (though I am not one of them) believe our 2013 world is now experiencing some part or aspect of that Great Tribulation.
Perhaps the simplest ploy is to call the judgments of the seven trumpets exactly that, but with a few extra words:
"The Sounding of the Judgments of the Seven Trumpets During the Great Tribulation of the Apocalypse."
There are, by the way, other trumpets both in John's book and elsewhere in the New Testament (e.g., Rev 1:10 and 4:1; the trumpet of God in 1 Cor 15:52 and 1 Thess 4:16; and other trumpets mentioned elsewhere, as in Heb. 12:19). Moreover, the judgment of the seventh trumpet subsumes the seven judgments of the seven bowls. What to do, what to do?
I leave it to you.
