Again, this is purely for learning purposes, not chas veshalom noge’a le-maaseh.
Whats the nature of a non-Jewish woman’s prohibition? Is it deoraisa or rabbinic? How is it derived? Are there differences in opinions? Thank you.
Answer:
Very briefly:
Getting married to a non-Jewish woman might constitute the Torah prohibition of lo titchaten bam. This depends on whether the prohibition applies to all nations, or not. See Rambam, beginning of Issurei Bi’ah chap. 12, and commentaries; Even Ha-Ezer 16:1, and commentaries.
Intimate relaitons in public are a Torah prohibition, which is subject to the halachah of kana’im pog’im bo. This is derived from halachah le-Moshe mi-Sinai (see Avodah Zarah 36b; Rambam, Issurei Bi’ah 12:4; Even Ha-Ezer 16:2).
Intimate relations in private are at the very least a rabbinic prohibition, and many consider them a Torah prohibition, as mentioned by the Kessef Mishnah (Yesodei Ha-Torah 5:1; see Me’il Shmuel; Ramban, Milchamos, Sanhedrin, Chap. Ben Sorer).
