The so-called "third temple" might be built, but not by God's will. It is not prophesied anywhere in either the old or new testaments; so the pretense has been squeezed (e.g., spiritualized) out of the text.
The following passage in Ephesians identifies the true holy temple of the Lord, of which all Christians are a part:
"Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God; And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone; In whom all the building fitly framed together groweth unto an holy temple in the Lord: In whom ye also are builded together for an habitation of God through the Spirit." (Eph 2:19-22 KJV)
Paul also identified the holy temple in the Corinthians:
"Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are." (1 Cor 3:16-17 KJV)
The holy temple is also identified in the Revelation of Jesus Christ as being located in the holy city, New Jerusalem (the Church;) and, again, it is not a physical building of any sort:
"And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it." (Rev 21:22 KJV)
The same was also mentioned in the Acts:
"God that made the world and all things therein, seeing that he is Lord of heaven and earth, dwelleth not in temples made with hands;" (Acts 17:24 KJV)

You probably have never even considered this, but neither of these is self-evident.
True...Jesus is the non physical spiritual temple...It is most definitely NOT the Catholic church or any particular religion...
The 3rd Temple is a physical temple...It is not Jesus Christ...It is Solomon's Temple, rebuilt...With the throne of David...
