Why is it that the tribe of Judah won't acknowledge the existence of the other tribes?

Mr Maurog is right.

during the reign of Solomon’s son, King Rehoboam, the kingdom of Israel split. 10 tribes followed Jeroboam in rebellion making the northern kingdom = Israel. Only Judah, and Benjamin and the Levites (who were scattered in the towns and cities) remained loyal to Rehoboam. These 3 tribes make up the southern kingdom = Judah.

read 1 Kings 12

Paul was a citizen of the kingdom of Judah(ie a Jew). But he wasn't just a Jew. nor was he merely a Benjamite. He was both. by birth, of the tribe of Benjamin - by national citizenship, a Jew. Philippians 3.5

Uh, Judah is a merge of three tribes, one of them Benjamin.

They were living too close and people intermarried until it was impossible to distinguish which is which. So they now are called by the largest of the original tribes, Judah. Judah, Simeon and Benjamin merged into Judah, but Levi which also was mingled in them did not, because Levites were a cleric caste, marrying only within themselves.

Also, all 12 tribes are Jews, so the point is moot.

Er, yes, that would make him a Jew.

Although the general name for the Jews originally comes from Judah's name, it includes all 12 of the tribes, not just Judah.

Thanks "jofuss" for sources!!!

Problem here is a Christian invention.

Judaism and its liturgies do not recognize NT, its teachings, its Apostles including "Paul"

And since the NT liturgies are not recognized by Judaism, the liturgies utilized by Judaism have no relevance to Christianity.

Therefore when claim is made of "tribe" based on OT "Kings 12" as compared to NT "Philippians 3.5" this is non-sequitor, "it does not compute".

Mitigating reasons for this include:

Both the Question and the Answers above are very narrow and very "Christian" of both OT and NT.

Understanding of the OT by Christendom is usually vastly different than the same OT understood by Judaism.

Judaism understands its liturgies.

Christendom almost universally misunderstands (by Judaism's standards) Judaism's liturgies.

Christendom utilizes to near exclusion only "English" and does not recognize the supporting liturgies such as Talmud, Torah shebik'Tav - Oral Torah, Mishnah, Midrashim, Zoharic writings, etc.

Judaism's understandings of OT is a very stark contrast to the Christian understandings of OT due in very large part to Judaism's usage of both the original Hebrew and the supporting liturgies.

Judaism's understanding does not recognize NT liturgies such as that known as "Philippians 3.5".

because of the scattering that took place in the old testament

of the tribes...judah has been kept more intact than the others.

I'm from the tribe of Ephraim. :)

Paul was a Jew...............and it really doesn't matter what he was. All I know is that the Lord used him in a mighty way

YEA WE DO AND THE 12 TRIBES ARE STILL IN EXISTANCE TODAY

LOOK IT UP THE 12 TRIBES OF ISRAEL ARE THE SO ALLED N3GROS..HISPANICS..AND WEST IDIANS
