Now I’ve only heard of the pre-wrath view recently, but what I get is that it’s closer to the midtrib view than it is to posttrib. Pre-wrath delineates between the first six seal judgments and the trumpet and bowl judgments. One flaw with this theory is that Scripture shows that it is the Lamb who opens the seals (Rev 5:5, 6:1).
The lamb opens the seals but it is men that actually do the things.
Everything that happens is a either God caused, or God allowed, the trumpet and bowls are God caused, men can't do those. But the seals are God allowed, but man caused. Think of the seals as something that God is restraining when the seal is loosed, God is no longer restraining, so men do what their wickedness has always wanted to do but has been prevented from doing.
It is at the 6th seal, that they say the wrath of God is come, as in it's arrived, it's about to start.
Not that it has been happening already. Think about the souls in the 5th seal, they ask how long will God
not judge the Earth, if the first 5 seals were a part of the wrath of God... He'd have already been judging, but instead of saying "It's already being done" they're told "rest a little season" you know "just wait awhile longer"
I think the main difference between pre wrath and any of the "-trib" views is the understanding of what the word "tribulation" means.
pretrib, post-trib, mid trib, all consider 'the tribulation" to be a 7 year period, pretrib will say it's a 7 year period of God's wrath, post trib will say it's a 7 year period of tribulation and God's wrath is only Armageddon (ignoring what Revelation 6:17 and Revelation 15:7 say), I'm honestly unsure of how mid trib characterizes whether tribulation is God's wrath or not.
Pre-wrath will see the first 5 seals (and the mark of the beast, seeing Revelation divided into 2 halves, chapters 4-11 and 12-22) as not the wrath of God, but tribulation caused by men. If you look through your bible and the context of the word tribulation, it's always related to persecution or violence caused by men. They will also generally not consider it "great tribulation" until after the midpoint, because that's when Jesus says great tribulation starts in Matthew 24, not before the midpoint but after.
So to be more accurate "pre-trib" is more pre 70th week, "mid trib" is still a form of pre-trib but mid 70th week (because they would be raptured before the great tribulation began), pre wrath is more formally known as post trib, pre wrath (after tribulation by men, but before the wrath of God), and "post trib" more accurately known as post-wrath.
It does to some degree boil down to what the definition of "tribulation" is.
because Jesus frames great tribulation with after the midpoint, but before the signs that match the sixth seal, I view "tribulation" to specifically be the war against the saints, which is characterized by the 5th seal, and the Mark of the Beast. (parallels)
Because Revelation 7:14 has the saints in heaven holding objects (like people with bodies do), described as having come out of great tribulation, I see it as consistent with Matthew 24:29. Those signs happened, they came out of great tribulation, therefore.. great tribulation is from that vantage point, a past event, before the trumpets and bowls.
Revelation 14 has kind of the same thing different details, mark of the beast is in effect, then Jesus is in the clouds, then there are saints in heaven before the vials filed with the wrath of God come out.
So it's a consistent pattern of tribulation -> Jesus in the clouds -> saints in heaven -> wrath of God on Earth
