According to Ezekiel, animal sacrifices are made during the Millennial Kingdom rule. At that time, the Dispensation of the Church (Grace) will be over. This will be the Dispensation of the Kingdom. At the second coming of Christ, there will be believers who go into the Kingdom who will not have glorified bodies. They will bear children, who will be born with a sin nature, and who will sin. Some of them will be very rebellious, in fact (Rev. 20:7-9). Animal sacrifices will be offered for the sins of these people. They will not be saved by Grace through faith. They will not have the in-dwelling of the Holy Spirit. How could they be saved by faith, since the Messiah is right there, walking in their midst? I repeat: the Dispensation of Grace is over at that time.

Under these circumstances, temple worship and sacrifice make perfect sense to me. I don't see how this is inconsistant with reformed theology.

This brings up issues I had never thought about: namely, that during the Kingdom, I suppose God will be doing more choosing. This has been His pattern throughout all of history: He chose the Jews, He chose the prophets, He chose the Apostles, He chooses us Christians.
