Yes, because they are converts to Judaism. There is more than one definition of a Jew:
1. Someone practicing Judaism
2. A descendant of Judah
Not all who call themselves "Jews" practice Judaism. I am ethnically a Jew by birth...our family, including me, never were "practicing" Jews. There are Jews living in Israel who claim to be atheists.
JEW
(praising). (1) A physical descendent of Abraham, Isaac, and Jacob; a son of the nation Israel by birth:
Acts 2:5 And there were dwelling at Jerusalem
Jews, devout men, out of every nation under heaven.
Doesn't state here that these "Jews" were just descendants of Judah.
Acts 22:3 I am verily a man which am a
Jew, born in Tarsus, a city in Cilicia, yet brought up in this city at the feet of Gamaliel, and taught according to the perfect manner of the law of the fathers, and was zealous toward God, as ye all are this day.
The apostle Paul was a Jew from the tribe of Benjamin
(Philippians 3:5), not Judah.
Romans 1:16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the
Jew first, and also to the Greek.
Romans 3:1 What advantage then hath the
Jew? or what profit is there of circumcision?
(2) A Jew who truly believes in God:
Romans 2:29 But he is a
Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
The above verse is describing a born again, blood washed Jew, not Gentile.
Gentiles do not become "spiritual" Jews or "spiritual" Israel when they come to faith in Christ. They remain Gentiles but become "adopted" sons and daughters and joint-heirs with Christ through faith.
Judah was one of the 12 tribes under Israel during the united monarchy of King David. There are pure ethnic descendants of Judah.
Jews are not just the physical descendants of Judah.....unless of course, you are of the same belief as British Israelism.
There are not 10 lost tribes of Israel!
Converts to Judaism have no blood link to the tribe of Judah.
Converts to Judaism have no blood link to ANY tribe of the 12 tribes of the children of Israel...they are not "physical" descendants of Abraham, Isaac and Jacob...not just the tribe of Judah (one of the sons of Jacob)
