Mishneh Torah, Marriage 1

Sugya Map: The Ontology of Acquisition

• Issue: The legal mechanism and scriptural source of Kiddushin (betrothal).
• Nafka Mina: Is a marriage bond created by the act (sexual/monetary/documentary) or by the Torah’s recognition of that act? Does "Rabbinic" status in Rambam denote a lack of biblical authority or merely a lack of explicit scriptural text?
• Primary Sources: Mishneh Torah, Marriage 1:1-2; Kiddushin 4b; Sefer HaMitzvot (Positive Commandment 213).

Text Snapshot

• "קידושי כסף מדברי סופרים" (MT 1:2): Rambam asserts monetary acquisition is midivrei soferim.
• Nuance: The Maggid Mishneh defends this by distinguishing between "Torah law" (explicit) and "Rabbinic derivation" (exegesis). Crucially, the Kessef Mishneh notes that even what is midivrei soferim via drash carries full biblical force.

Readings

• Rambam (Sefer HaMitzvot): Originally held only bi’ah (intercourse) was biblical, later refined to include document and money as Torah-level through exegesis.
• Rav Kapach: Argues that Rambam’s mature view, supported by his son (Rabbenu Avraham), classifies all three methods as de'oraita, treating the midivrei soferim label as a technical category of exegesis, not a demotion of status.

Friction

• Kushya: If kiddushin via money is midivrei soferim, how can it effect a change in status (e.g., prohibition to the world, get requirement) that mirrors Torah law?
• Terutz: As Nachal Eitan notes, Rambam’s taxonomy is semiotic. "Divrei Soferim" describes the method of discovery (the gezerah shavah), not the weight of the obligation. The Sages "formalize" the Torah’s intent; the authority remains divine.

Intertext

• Gittin 49b: The Gemara discusses takanot that are technically d'oraita but framed as Rabbinic. This validates Rambam’s approach: the "Rabbinic" label is a meta-commentary on the source of the instruction, not the validity of the law.

Psak/Practice

• Meta-psak: In the modern Beit Midrash, we treat the "Rabbinic" label as a pedagogical tool. When Rambam says midivrei soferim, he is identifying the process of legal evolution—that Torah law is alive and grows through the Sages' interpretive engine.

Takeaway

Rambam’s classification of kiddushin as midivrei soferim is not an admission of lesser status, but a profound assertion that the Oral Law is the primary vehicle through which the Torah’s internal logic becomes external reality.
