Not part of my view as far as I don't believe Christians will be doing sacrifices either before or after the return of Christ.
I'm not sure how you are reading this. Is this temple viewed to be before Christ returns or during the millennium?
I have never thought that we christians would do sacrificing. But I'm sure there are some fringe groups that edge on being Jewish themselves, even though they are not, that may want to participate with the Jews before Christ returns. Like I said, the Jews will build the temple and do the sacrifices, before Jesus returns. This is not part of the millennial reign. The only annoyance is that it's not clear what you are talking about.
