Hello again Louis,
What you are not understanding is that there will be a group referred to as "the great tribulation saints" and who are the ones who will be gathered by the angels. This group is introduced in Rev.7:9-17. This group are those who will turn to Christ after the church has been gathered and during the tribulation. So, your uppercase and bolding is not necessary, as it is not going to change who is being referred to, as you are not differentiating between the church and the great tribulation saints. The elect and the saints that are being referred to are those great tribulation saints who will make it alive through the tribulation period until Jesus returns to the earth.
In Rev.7 John sees the following group:
"After this I looked and saw a multitude too large to count, from every nation and tribe and people and tongue, standing before the throne and before the Lamb. They were wearing white robes and were holding palm branches in their hands."
The fact that they are from every nation, tribe, people and language makes them Gentiles. Then the elder asks John the following question:
"These in white robes,” he asked, “who are they, and where have they come from?”
"“Sir,” I answered, “you are the one who knows.”
Keep in mind that in Rev.1:11 John was previously asked to write letters to the seven churches. The elder even asks John who they are and he says he doesn't know. Therefore, the fact that the elder is now asking John who these in white robes are demonstrates that they are not the church, but another group being introduced. The elder then tells John who this group is:
So he replied, “These are the ones who have come out of
the great tribulation; they have washed their robes and made them white in the blood of the Lamb."
As I previously told you, throughout chapters 1 thru 3 only the word "Ekklesia/church" is used. After the end of chapter 3 the word "church" is never used again, but the word "hagios" translated as "saints" is used throughout the narrative. The reason for this is because in Rev.4:1-2 John hears that same voice that sounds like a trumpet (Jesus) saying "come up here." This is a prophetic allusion to the church being gathered. That voice that sounds like a trumpet is synonymous with the "trumpet of God" found in 1 Thess.4:16 when Paul is describing the resurrection of the dead and the living being changed and caught up.
The saints referred to above is again referring to those great tribulation saints who will come to Christ after the church has been removed from the earth and during the tribulation. Just always keep in mind that the church is not appointed to suffer God's wrath and therefore cannot be the saints that are referred to in the scripture.
The church will not even see the antichrist, as we will be gathered before he is revealed. By the time the above happens, all believers belonging to the church will have already received their immortal and glorified bodies and will be returning with Christ to the earth to end the age.
Until you understand the difference between the church and the great tribulation saints, the scriptures that you continue to post will confuse you regarding end-time events. The word of God says the following regarding the church and God's wrath:
========================================================
"Therefore, since we have now been justified by His blood, how much more shall we be saved from wrath through Him!" - Rom.5:9
"They tell how you turned to God from idols to serve the living and true God, and to wait for his Son from heaven, whom he raised from the dead—Jesus, who rescues us from the coming wrath." - 1 Thess.1:10
"But since we belong to the day, let us be sober, putting on the breastplate of faith and love, and the helmet of our hope of salvation.
For God has not appointed us to suffer wrath, but to obtain salvation through our Lord Jesus Christ." - I Thess.5:9
"Because you have kept My command to endure with patience, I will also keep you out of the hour of testing that is about to come upon the whole world, to test those who dwell on the earth." - Rev.3:10
=========================================================
Rev.13:7 which you posted above, takes place during the time of the God's wrath and the reign of the beast. By making the "saints" as referring to the church, you would be putting the church as being on the earth during the time of God's wrath, which as the scriptures posted above make clear, the church is not appointed to suffer.
As I said before, the principal to this is that Christ already suffered God's wrath on behalf of every believer. You are being confused by the use of the word "saints" and "the elect" and applying them as referring to the church.
