Many Protestant churches teach that the Jews have a special way into heaven without Christ. When they get there they will rule over Christians.
So they teach that Jews who hate Christ will rule over Christians who love and follow Christ.
So why be a Christian? According to the churches Jews can be evil and still rule in heaven.
Who thinks this stuff up? The doctrine sounds very Talmudic. It certainly isn’t Biblical.
Why do you believe the Jews are Israelites? Because they say so? The scripture tells us exactly who is Israel, no spiritual Israel required. Do you believe scripture?
