This article in PDF: WHO IS A JEW
CHINESE ENGLISH JAPANESE POLSKI ROMANIAN
Who is a Jew? This question is neither as simple – nor as complicated – as the Jews present it. The original, official version was that if your mother was a Jew, then you are a Jew. Period. No apparent room for discussion here.
“The Code of Jewish Law clearly states that a child of a Jewish mother is Jewish, regardless of the father’s lineage (or whatever else may show up in a DNA test), while the child of a non-Jewish mother is not Jewish. Matrilineal descent has been a fundamental principle of Torah since the Jewish people came into existence.”[1]
