The Church did not replace Israel. Israel has been the believers, first the Jews and then the Gentiles.
The OC Mosaic Priesthood was replaced with the NC Melchizedek Priesthood of Christ.......

The OC Priesthood or sacrifices will never ever be accepted by Jesus in the future, Temple or no Temple........
What about Revelation 11:1-2 SANCTUARY, COURT AND HOLY CITY
Revelation 11:
1 And was given to me a reed like-as rod saying "rouse! and measure!
the Sanctuary<3485>
of God and the Altar[
Golden Altar] and those worshiping in it
2 and
the Court/Fold<833>[
Priests/Lavar/Altar of Sacrifice] outside of
the Sanctuary,
be casting-out!<1544> out-side<1854> and no it thou should be measuring, that it was given to the Gentiles/Nations.
And the holy City they shall be treading<3961>forty two months.
OC Mosaic Priesthood cursed forever?
Hosea 4:6
My people are destroyed for lack of knowledge. Because you have rejected knowledge,
I also will reject you from being priest for Me;
Because you have forgotten the law of your God, I also will forget your children.
Malachi 2
1 “And now, O priests, this command is for you. 2 If you will not listen, if you will not take it to heart to give honor to my name, says the Lord of hosts, then I will send the curse upon you and I will curse your blessings. Indeed,
I have already cursed them, because you do not lay it to heart.
3 Behold, I will rebuke your offspring, and spread dung on your faces, the dung of your offerings, and you shall be taken away with it
7 For the lips of a Priest should guard knowledge, and people should seek instruction from his mouth, for he is the messenger of the Lord of hosts.
8 But you have turned aside from the way. You have caused many to stumble by your instruction. You have corrupted the covenant of Levi, says the Lord of hosts, 9 and so I make you despised and abased before all the people, inasmuch as you do not keep my ways but show partiality in your instruction.”

Hebrews 7:12
For being changed/translated<3346> the Priesthood, out of necessity also, of Law a change/translation<3331> is becoming,
