I don't think he believes the church goes through the tribulation? The bible does not teach that.
I am supposing the following is why you think the Church avoids the time of Tribulation. Let me know if not.
If the Tribulation is God's Wrath, and the Church won't go through it because they are promised to be spared from His Wrath, then why are the people who "have the testimony of Jesus Christ" the ones being targeted and killed during the Trib,
but those who took the Mark are untouched by His Wrath?
Rev 12:17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
I anticipate you may respond that Satan is killing the Saints, not God. Then by default the Tribulation cannot be God's Wrath. He doesn't kill His own Children, that's been the sole domain of the devil. He certainly doesn't leave evildoers untouched by His Wrath; the armies of those who took the Mark are still there at His Second Coming ready to fight Him! This is when He delivers His Wrath, everything prior is Satan's work.
Look what atrocities Satan did to Job exercising his own power, that God allowed him to use, and look what God did to the wicked during Noah and Lot's time - destroyed every one of them. The earth will know when God's Wrath hits, and none of His Children will be on the receiving end when that happens, so the Tribulation cannot be the same as God's Wrath.
Rev 16:1 And I heard a great voice out of the temple saying to the seven angels, Go your ways, and pour out the vials of the wrath of God upon the earth.
