I see that in Ezekial there is mention of a prince that offers a sin sacrifice in the Temple. Ive heard that most if not all Christians and Jews believe these verses (Ezekial 40...or there about) are messianic verses pertaining to the 3rd (millennial) Temple. Who is this prince and why would he offer a sin sacrifice? If Jesus was the once-and-for-all sacrifice, why would the sin sacrifice be brought back? And who is the prince if not the messiah?
Some Christians believe the Jewish Temple will be rebuilt. Not all. Most of us regard any future temple to be fundamentally irrelevant as the only relevant temple is Jesus Himself. In John's gospel, ch. 2 Jesus says, "Tear down this temple, and in three days I will raise it up." The text is clear that the temple initially being discussed is the temple structure in Jerusalem but the temple raised up is His own flesh.
For Christians, historically, the destruction of the temple in 70 AD represents a fundamental break, a culminating moment signifying that the old things are a thing of the past, as they had served their purpose in pointing toward the coming of the Christ, whom Christians believe to be Jesus.
As such for most Christians there's simply no reason to believe that a temple will be rebuilt in Jerusalem, or rather that such an event is meaningless one way or the other. Additionally most Christians today--and most of history--have been what is called "Amillennial" a somewhat confusing term as it would suggest a non-belief in the Millennium. In actuality it refers to a belief that the Millennium, mentioned only once in the Bible, near the end of John's Apocalypse, is non-literal; and ultimately refers to the entire reign of Christ from His ascension to His return. The Millennium does not refer to a time of abundant peace on earth, but the reality of Christ's reign at the right hand of the Father and the exercising of His kingdom power and authority through the preaching of the Gospel and the ministrations of the Christian Church--the proclamation of the Gospel, the administration of the Sacraments, the feeding of the hungry, etc. As the kingdom of God is not a matter of earthly power and government, but rather the reality of God breaking into our world through Jesus, the forgiveness of sin, reconciling God and man together in Christ, by His death on the cross and His resurrection from the dead.
So for most of us there is no future Millennium. Rather, when Christ comes again it is "in glory" and "to judge the living and the dead", or to quote St. Paul in 1 Corinthians 15, "deliver all things to the Father ... and God may be all in all". When Christ comes there is, indeed, peace and justice on the earth, but not for a short thousand years, but for
eternity. The "new heavens and the new earth" which are mentioned by the Prophet Isaiah (Isaiah 65), and reiterated by St. John of Patmos in his Apocalypse.
This is the view of Roman Catholic, Eastern Orthodox, Lutheran, Anglican, and most Mainline Protestant churches.
As for Ezekiel's text rather specifically, he is almost certainly referring to the return from captivity. In chapter 37 the prophet sees in a vision a valley of dry bones and God commands him to command the dry bones to live again and they do, thus beginning a series of visions and statements about the return of the people from Babylon. The rebuilt temple isn't a third temple, but is rather the second temple constructed under the supervision of Zerubbabel, the same temple that was added to by Herod the Great and subsequently known as "Herod's Temple" the one destroyed by the Romans in the year 70.
Strict literalists might like to pick at details insisting that the details be understood strictly literally, but that's not a problem if one doesn't feel the need to insist on such wooden literalism on every matter of minutia. The Bible is replete with details that arguably shouldn't be read literally, such as the Prophet Joel's mention of the sun turning dark and the moon turning red--a prophecy quoted by St. Peter in the 2nd chapter of Acts as having been fulfilled, when very obviously this event did not literally transpire on Pentecost then.
