The only reason to call the saints in Rev 5 onward "tribulation saints" not part of the church, is the starting premise that the church has already been raptured. However, this is not supported by any text in Revelation (or anywhere in the Bible), and is forced onto the scripture.

Perhaps a better phrasing is that one interpretation of Scriptural Prophetic events allows for the removal of the Church at the Rapture prior to the Great Tribulation. Even with the Church and Holy Spirit removed, there are still believers during the Great Tribulation period, also known as 'tribulation saints'.

While there might not be a specific verse stating such, it still is a consistent eschatology,

Yes, it is consistent with pre-trib escatology.

However, there is not a single verse in the bible that clearly teaches that idea, and multiple that say the exact opposite.

The bigger problem, though, is that if the Holy Spirit is gone, how will people come to believe in Jesus. For no one comes unto Jesus unless the Father first draw him.

As one explores pre-trib, one constantly finds issues like this, and has to re-intepret scriptures contrary to there face value meaning.
