That must be wrong. Ezekiel prophesied animal sacrifices as sin offerings but Calvary FINISHED all sacrifices and opened the Way to the Father. The New Covenant temple is being built with living stones - believers.
That the Prophecy of Ezekiel will be fulfilled as it is written is evident in that all Prophecy is always fulfilled as it is written.
One thing we must never forget is that vicarious sacrifice of animals, that is, an animal dying in the stead of the sinner for the purpose of a temporary atonement and forgiveness of sins...never saved anyone.
So we contrast the sacrificial system of the Law (and all animal sacrifice, which is not exclusive to the Covenant of Law, but dates back to the Garden, and can be seen performed by Abel, Noah, Abraham, Job, and Jacob prior to the establishment of the Covenant of Law) with the Sacrifice of Christ. The former could not take away sins...
Hebrews 10:1 & 4
King James Version (KJV)
1 For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
4 For it is not possible that the blood of bulls and of goats should take away sins.
...and the latter not only takes away sin, it makes one complete in regards to remission of sins forever...
Hebrews 10:14
King James Version (KJV)
14 For by one offering he hath perfected for ever them that are sanctified.
"Perfection" here, in the Greek, means completion, a bringing to an end.
All of that to point out that though sacrifice will resume in the Millennial Kingdom, this is an issue of Heritage with Israel, not an issue of atonement, nor does it conflict with the Atonement. of the Cross.
You say "Calvary FINISHED all sacrifices" yet we see Paul willing to participate in an offering long after Calvary:
Acts 21:17-26
King James Version (KJV)
17 And when we were come to Jerusalem, the brethren received us gladly.
18 And the day following Paul went in with us unto James; and all the elders were present.
19 And when he had saluted them, he declared particularly what things God had wrought among the Gentiles by his ministry.
20 And when they heard it, they glorified the Lord, and said unto him, Thou seest, brother, how many thousands of Jews there are which believe; and they are all zealous of the law:
21 And they are informed of thee, that thou teachest all the Jews which are among the Gentiles to forsake Moses, saying that they ought not to circumcise their children, neither to walk after the customs.
22 What is it therefore? the multitude must needs come together: for they will hear that thou art come.
23 Do therefore this that we say to thee: We have four men which have a vow on them;
24 Them take, and purify thyself with them, and be at charges with them, that they may shave their heads: and all may know that those things, whereof they were informed concerning thee, are nothing; but that thou thyself also walkest orderly, and keepest the law.
25 As touching the Gentiles which believe, we have written and concluded that they observe no such thing, save only that they keep themselves from things offered to idols, and from blood, and from strangled, and from fornication.
26 Then Paul took the men, and the next day purifying himself with them entered into the temple, to signify the accomplishment of the days of purification, until that an offering should be offered for every one of them.
It seems that James, and the Elders at Jerusalem (who were a confused bunch in my opinion, lol) still continued in the practices of their heritage, though, as we can logically conclude with Paul, did not mean they were "keeping the Law" as a means of either relationship or salvation. Nowhere are Jews demanded that they stop being Jews in Scripture, nor are they demanded they refrain from their heritage. I think we can safely say that this unique body, Israel, stands apart in History as a created people of God. And while they were but a picture of the "one man" God would create, the Church, that is, some of us believe that they still have a role to play in Eschatological matters. There will be a rebuilt Temple for Antichrist to defile, and there will be restored Levitical Service. And it is my own view that the Prophecy of the Old Testament will unfold as it has been written, but the sacrifices offered there will not have any more salvific value than it did for Israel when they were practicing it in the past.
Only the Sacrifice of Christ can take away sins, and it is only through the Cross that salvation is effected. So I see no conflict in reinstituted sacrifice in the Millennial Kingdom.
God bless.
