So, you are equating Rome with the "temple of God"?
I thought the only structure so named was built by Solomon in Jerusalem, destroyed by the Babylonians in 586BC, restored 70 years later and then finally destroyed by Romans in 70AD. Or course, Christians are also called the "temple of God" (1 Corinthians 3:16), but it is hard to understand 2 Thess 2:4 as referring to anything but a physical temple.
A reconstructed temple in spiritual Sodom (earthly Jerusalem where our Lord was crucified--Rev 11:8) appears to be a prerequisite.
The Pope calls himself the "vicar of Christ" and I am disturbed by the implications of this claim. "For there is one God, and one mediator between God and men, the man Christ Jesus." (1 Tim 2:5). However, the "first beast" has not yet received the "[deadly] wound by a sword" and been healed by the second beast (Rev 13:11-14). These events, which must precede the "day of the Lord" (Rev 14:14-16), have not yet happened.

We do not know the day or the hour of Christ's return, but we are not ignorant of the detailed events which must precede it and, therefore, will not be deceived, as many will be, by the arrival of the false Christ who has been permitted to make war on the children of God.
None of these events have happened. Christ's return is not imminent (May 21st).
Every “temple” from now to the return of the Lord will be a false temple, constructed to please the kabbalists, not God.
This definitely includes “St. Peter’s” basilica.
