Where am I coming from? Show me my posts that you think are specific?
Gentile Christians are "grafted in" branches. Read the Book of Romans, or Hebrews for starters. I don't need to claim some faux bloodline, completely unproven. We should appreciate all the sacrifice the Jews have been through, particularly the One whose birthday we're about to celebrate (and don't get into a argument about Dec. 25, that was a day that was picked).
Gentile Christians are grafted in. So what? You don't need to care about bloodlines, certainly, and neither do I, being a Christian. Then why does it worry you so much?
I'm debating the topic; you're reacting to it.
