For JEWS ONLY! But who is a Jew?

Jewishness is inherited from the mother only, NOT the father.
In the Biblical Book of Ezra, chapter 10, Ezra ejects all children born to non-Jewish mothers, even though they all had Jewish fathers.
Ezra is never criticized for this by any prophet or classic Torah book.

The Talmud says 5 times that the child of a Jewish MOTHER is Jewish: Yebamot 17A, Yebamot 23A, Yebamot 100B, Kidushin 68B, Sanhedrin 21A.

Reform and Conservative converts are NOT Jewish because their Rabbis: accept heretical beliefs and publicly desecrate Shabbat (Rambam, Hilchot Shabbat 30:15) and DO NOT follow correct conversion procedures.
