I think we have a failure to communicate. I have nothing against Christians. I count many as good friends. I welcome their support for Israel. Many live there and call it their home. It is only that Jewish law is clear on the treatment of a Jew who publicly renounces his faith for another. A Jew who converts to any other religion, including Christianity is an apostate. They have given up their status a Jew. A "messianic Jew" is an oxymoron. It is like kosher pork. They are either Christian or Jew.
They cannot be both. To say otherwise is a bald faced lie. Point blank.
I see. Well, the atheist Jew can be glad that he or she is still considered Jewish, Christian be damned. The atheist Jew gets the benefit of the doubt. The ethnic Jew who is a Christian doesn't.
Beam me up, Scottie.
