I am not sure I am understanding your objection. What exactly do you mean by "the return of Christ is when the living believers are gathered together with him" I certainly believe that Christ will gather living believers to him at his coming. Is this what you meant?
Maybe I misunderstood you. It seemed what you were saying is that the Lord gathers the believers (The Rapture - I don't like the term so I tend to not use it) before his the wrath is poured out, at a time separate from his actual appearing. I believe scripture states that we are gathered to Christ at his actual appearing, not before.
No. The Temple of God among Christians is the Christian him/herself. The Temple of God referenced in Revelation is the new Temple built by Israel under treaty with the antichrist.I'll ignore the pejorative and simply say that my comment here, even if you don't accept the second part, negates the possibility of the "Temple" being any church.
There is nothing in the scripture about a rebuilt temple. That is an inference, not an explicit teaching, and IMO a bad inference at that.
And yes the individual Christian is the temple of God, but so is the church.
For He Himself is our peace, who made both groups into one and broke down the barrier of the dividing wall, by abolishing in His flesh the enmity, which is the Law of commandments contained in ordinances, so that in Himself He might make the two into one new man, thus establishing peace, and might reconcile them both in one body to God through the cross, by it having put to death the enmity. AND HE CAME AND PREACHED PEACE TO YOU WHO WERE FAR AWAY, AND PEACE TO THOSE WHO WERE NEAR; for through Him we both have our access in one Spirit to the Father. So then you are no longer strangers and aliens, but you are fellow citizens with the saints, and are of God's household, having been built on the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone, in whom the whole building, being fitted together, is growing into a holy temple in the Lord, in whom you also are being built together into a dwelling of God in the Spirit. - Eph 2:14-22 NASB
he will also call the memorials to cease, and will commit the "Abomination of desolation", so those both fit much better a rebuilt temple for israel in end times!
Nothing in scripture about some eschatological bad guy causing "memorials" to cease. And the abomination of desolation was the 70AD destruction of Jerusalem by the Romans. could that point to a greater fulfillment in the future? Maybe, but scripture doesn't explicitly say.
