It is the Church coming back with the rest of the saints since the Church has been married to the Lamb in Rev.19:7 (Eph.5:30, 2Cor.11:2).
It is not only the Church that returns with Christ, but all departed saints, including Tribulational ones.
But FTD, it doesn't mention a church coming back anywhere in these verses.
2Cor.11:2 For I am jealous over you with godly jealousy; for I have espoused you to one husband, that I may present you as a chaste virgin to Christ.
Eph.5:30 For we are members of His body, of His flesh, and of His bones. (32)This is a great mystery: but I speak concerning Christ and the church.
Revelation 19:7 Let us be glad and rejoice, and give honour to Him: for the marriage of the Lamb is come, and His wife hath made herself ready."
His wife is ready to be joined with His bride and that "marriage" happens on earth, at His 2nd Advent. His "wife" is His elect. Those whom He has already justified, (Romans 8:28-30). His bride are those of "free will" who have accepted Him and are now part of His family.
All three of those verses are, as you said, about Christ and His church, His people but no where does it say they are going to be raptured and come back with Him.
It is not only the Church that returns with Christ, but all departed saints, including Tribulational ones.
I don't find anywhere that the "church" returns with Christ. All departed saints do.
We will go through the tribulation and will be refined:
Zechariah 13:9 And I will bring the third part through the fire, and will refine them as silver is refined, and will try them as gold is tried: they shall call on My name, and I will hear them: I will say,'It is My People:' and they shall say 'the Lord is my God.'
How is gold and silver refined? Melted down and the slag is thrown to the side. His children will remain pure and not fall for Satan's lies. To go through this refinement we must be here.
