This is a new form of worship, found neither in the law of Moses nor in the New Testament.
Christ is the sacrificial "Lamb" that was the final sacrifice for sin, throughout the New Testament and the Book of Revelation.
He announced that He would fulfill the New Covenant in His Blood, at the Last Supper in Matthew 26:28.
This fact shows your claim of a change to a different covenant in the future, with renewed animal sacrifices for sin, to be in error.
Rev_5:6 And I beheld, and, lo, in the midst of the throne and of the four beasts, and in the midst of the elders, stood

the Lamb:

the Lamb, saying, Great and marvellous
are thy works, Lord God Almighty; just and true
are thy ways, thou King of saints.
Rev_17:14 These shall make war with the Lamb, and
the Lamb shall overcome them: for he is Lord of lords, and King of kings: and they that are with him
are called, and chosen, and faithful.

There is no indication of your claimed different future covenant in the Bible.
It only comes from you.
