False. Look at Rev 13, there is no rapture involved with either beast rising up.
No passage of the bible, any bible, says anything remotely like that. Christians are promised to be persecuted and even killed in the trib, in every passage that speaks of the trib. Christians are NEVER gone during that period. It cannot even exist without them being the tribulation is Christians experiencing tribulation from the enemy. That is why it's called tribulation.
The bible says the church will go through the tribulation. The 144,000 Christian Jews do. The two witnesses, which are two prophets and two Christian churches do. Revelation 20 also says Christian beheaded martyrs do. Revelation 13 speaks of Christian saints so they do. Revelation 12:17 says satan will wage a war against Christians, and that is seen starting in Revelation 13. The 5th seal shows dead Christians wanting vengeance but are told to wait until more of their own Christian brothers are killed like they were. That is the killing of Christians in the trib. Christ said Christians will go through the Great Tribulation in the Olivet discourse.
The doctrine teaching the church is gone before the trib starts is not a biblical doctrine. The only way to be gone is to commit Apostasy and leave the church which is Apostasia in the Greek and is what many teach is the rapture but it is Apostasy not Rapture. Even Apostates will still be here during the trib, just on the side of the Enemy.
