To clarify, the red heifer might have represented and foreshadowed a non-determined, non-descript idea of a Jewish messiah. But ultimately, the Jews did not accept Jesus in the flesh as their Messiah, making Jesus a false Prophet in their view.

Christians today are interested in the Red Heifer because of its significance to biblical prophecy's timeline, specifically the nearness of the Christian Jesus' return.

Christians are way off base if they are excited about the rebuilt temple and re-establishment of the Jewish sacrificial system for any reason other than a marker on the prophetic timeline. A restored sacrificial system would mean Jesus dying on the cross and being raised from the dead is meaningless. If Jesus, as the ultimate sacrifice, is not enough, what hope do we have? A dead red heifer?

By far, the majority of Christians are supportive of Israel because we share the same Old Testament Heritage and God, so it's not fair to portray them all as radical nationalists because of a few loudmouth idiots. It's like me saying all Jews are stupid because you made an error in your article.
