The concept of paternity as the determining factor in progeny being considered as having Jewish descent is a constant in the Hebrew Bible, as the authors of the Report elaborated: “both the Biblical and the Rabbinical traditions take for granted that ordinarily the paternal line is decisive in the tracing of descent within the Jewish people.” Numerous examples in the Hebrew Bible determine a child’s status by the father’s tribe. The Report further asserts, “in the Rabbinic tradition, this tradition remains in force,” citing as prooftexts examples of Priestly status–“the child of an Israelite who marries a Kohenet is an Israelite” and the Talmudic precept, “the most important parental responsibility to teach Torah rested with the father (Kiddushin 29a; df. Shulchan Aruch, Yoredeah 245.1).” Only in the case where “the marriage was considered not to be licit, the child of that marriage followed the status of the mother (Mishna Kiddushin 3.12, havalad kemotah).” The Report offers a sociological interpretation of the reason for matrilineal descent in illicit unions: “the woman with her child had no recourse but to return to her own people

In Contemporary Israel – The Problem
Lev Paschov, an Israeli soldier who immigrated to Israel under the Law of Return from the Former Soviet Union, was killed while on active duty in Southern Lebanon in 1993, and buried twice. He was first interred in a regular Israeli military cemetery, but after it was discovered that his mother was not Jewish, his body was exhumed, and Paschov was buried a second time, in a cemetery for non-Jews.
For many Israelis, the macabre end of Paschov’s brief life journey was deeply disturbing. How was it possible that someone could be welcomed to Israel under the Law of Return, serve the Jewish state’s army, and die defending his adopted homeland, and still not be considered Jewish enough to be buried alongside his comrades?

Responsa of Rabbi BenZion Meir Hai Uziel, the chief rabbi of Israel in the 1940s and 1950
…From here we learn,that a patrilineal Jew brought by his father for a conversion should be accepted by the beit din. Even though this child is called the child of the Gentile woman, he is still considered zera yisrael (of Jewish stock)… everyone agrees that children of a Jewish man born to a Gentile woman are called zera yisrael, therefore, when the father brings him to convert, the child reverts to his original lineage. Responsa Piskei Uzziel BeShe’eilot Hazeman #64
…מכאן אנו לומדים במכל שכן כשגוי זה הוא בן ישראל מנכרית ואביו מביאו להתגייר שבי”ד נזקקים לגרותו משום דאע”ג שהוא נקרא בנה של הנכרית אינו יוצא מכלל זרע ישראל… הלכך כשאביו הביאו להתגייר חוזר הילד לעיקר זרעו, … הא למדת דבן הבא מן הנכרית נקרא זרעו של ישראל ועובר עליו משום ומזרעך לא תתן להעביר למולך, הלכך אם בא לגיירו מצוה עלינו להזדקק לגרותו כדי לכפר עון האב מאחרי הגרות ולבל ידח ממנו נדח. ואין לחוש שמא יגרר אחרי אמו דאדרבא אם דוחים אותו ועוקרים אותו ממקור חייו וזרעו שהוא אביו ודאי שיטמע בין הגויים ויכפור באלהי ישראל, וישנא תכלית שנאה את היהדות ותורתה…
MATRILINEALITY AND PATRILINEALITY IN JEWISH LAW AND COMMUNITY, PART 2, Rabbi Ethan Tucker
The 2021 study found that in the past decade, 61% of Jews married non-Jewish partners. And nearly three-quarters of non-Orthodox Jews who married since 2010 wed non-Jews. Intermarriage is quite rare among Orthodox Jews.
Whether intermarried couples are raising their kids Jewish has been a perennial concern of Jewish communal planners and institutions worried about the vitality of the Jewish future. The survey found that virtually all in-married couples are raising their children Jewish. In addition, most intermarried couples (57%) are raising their kids Jewish, with about half of that number saying they are raising their children to be Jewish by religion.
Another 12% of intermarried couples said their children were being raised “partly Jewish by religion,” meaning that overall, the survey found that more than two-thirds of children of intermarriages are being raised with some Jewish identity.
