Ethnic doesn't mean anything.
In the long run, spiritually speaking, you're right. After all, we can all trace our roots back to THE DUST. However, the Bible is an ethno-centric Book with a meaning and purpose, as God has chosen all TWELVE TRIBES - not just the Jews - to ultimately become His Servant Nation, His Light to All Nations.
If you left The Jewish People, you're not Jewish anymore.
The Bible refers to Am ISRAEL - not merely
Shevet Yehudah. Klal Yisrael is all TWELVE TRIBES - and only a relatively small portion of those Israelite peoples are Jewish, ethnically speaking.
I'm sure you can't trace your matrilineal descent to Israel.
Very few can, eh? Even as Jews go by traditions that they're ethnically Jewish, although Jews prefer to focus on the RELIGION of Judaism than the
Tribe of Judah or Southern Kingdom of Judah (with its coalition of Jews, Levites and Benyamin) - since they also can't prove their descent - those who understand and embrace the Hebrew roots, the Israelite origins of the West, specifically Joseph as the Anglo-Saxons claim descent as we ALONE (not Indian or African CONVERTS to Judaism) bear the unique biblical birthmarks of fulfilled prophecies as world leader and feeder.
As you know, Joseph and Judah (with all the tribes) are to increasingly become known and reconciled and reunited. Both Houses need to clean house, so to speak, so help us God, to return ever closer to the God of Abraham, Isaac and Jacob. He says He will bring it to pass. I trust He is able.
For the record, if folks don't believe that Anglo-Saxons are JOES, I don't lose sleep over it, merely wish such would prayerfully consider it and if they live in Israel at least hear Yair Davidiy out or question Rabbi Avraham Feld about it in greater detail to your satisfaction. Regardless, it is because of this strong belief that I have that I support the "Right" in Israel as a staunch Christian Zionist. Other Christian Zionists who also believed in our Israelite identity, such as Orde Wingate for one, were mightily used of God to bless Judah and Eretz Yisrael.
I wish one and all
Chag Hanukkah Sameach and hope folks join with Gershon Salomon and the Temple Mount Faithful for their noble demonstration - this Tuesday, if I remember correctly.
