Mishneh Torah, Foreign Worship and Customs of the Nations 8

Sugya Map

• Core Issue: The threshold of "human agency" (ma'aseh adam) required to transform neutral matter into avodah zarah (forbidden for benefit).
• Primary Sources: Avodah Zarah 45a–53b, Temurah 28b–29a, Chulin 41a.
• Nafka Minot:
  • Does the prohibition of avodah zarah derive from the nature of the object or the act of the worshiper?
  • Can a person prohibit an object they do not own?
  • The status of "accessories" (meshameshei avodah zarah) vs. the deity itself.
  • The efficacy of nullification (bitul) by a gentile versus a Jew.

Text Snapshot

• MT 8:1: "It is permitted to derive benefit from anything that has not been manipulated by man (lo na'asah adam)... even though it was worshiped."
• Leshon Nuance: Rambam uses lo na'asah adam as a metaphysical boundary. The dikduk here is vital: the prohibition is not merely the act of worship, but the interaction between the human subject and the object that creates a "forbidden status."
• MT 8:10: "A false deity belonging to a Jew can never be nullified."
• Nuance: The ontological shift for a Jew’s idol is permanent—an "eternal ban"—whereas a gentile’s idol is conditional on the ongoing reverence of the idolater.

Readings

1. The Ohr Sameach on Agency and Ownership

The Ohr Sameach (8:1:2) grapples with the Rambam’s ruling that one cannot prohibit a colleague’s animal through idol worship unless they possess the animal. He cites Rashi (Chulin 41a), who suggests that if one performs a siman of shechitah (ritual slaughter), the animal is acquired via shinui ma'aseh (a change in form). The Ohr Sameach argues that the Rambam maintains a strict ontological view: because the Jew intends only to "cause grief" (le-tza'ari) to his colleague, there is no shinui that effects a transfer of ownership, and thus, no issur takes hold. He masterfully reconciles the Rambam by asserting that the issur of avodah zarah is fundamentally linked to the kinyan (ownership) of the person performing the prohibited act. Without ownership, the act is rendered legally impotent.

2. The Peri Chadash on "Public Springs"

The Peri Chadash (8:1:1) addresses the Rambam's exclusion of public springs from the prohibition of avodah zarah. He notes the kushya regarding why the public nature of the spring is the pivot point. He suggests that while we assume individual handling (t'fisat yad) constitutes human manipulation, the rabbim (public) status effectively nullifies the individual's "claim" or "manipulation" of the water. He rejects the Shach’s assertion that "detached" water is always forbidden, arguing that the Rambam operates on a principle where the nature of the entity's usage dictates whether a human act can "latch onto" it to impart the status of a deity.

3. The Sha'ar HaMelekh on Two Verses (Shnei Ketuvim)

The Sha'ar HaMelekh (8:1:1) dives into the technicality of whether chalipei chali'in (exchange of an exchange) is forbidden. He attempts to resolve the Tosafot dilemma—how can we derive laws from shnei ketuvim when the two categories (avodah zarah and shevi'it) are mutually exclusive? He posits that the Rambam follows the view that the prohibition of chalipei chali'in is a gezerat hakasuv (divine decree) that transcends the logical constraints of shnei ketuvim. He suggests that the Rambam sees the prohibition not as a result of a legal derivation, but as an inherent status of the "forbidden object" that propagates through exchange.

Friction

• The Kushya: If the Rambam asserts that an animal is only forbidden if one performs a ma'aseh (act) upon it (e.g., shearing, slaughtering), then why does the Rambam forbid a tree that was planted for idol worship, even if it wasn't worshiped yet? Is planting not a ma'aseh?
• The Terutz: The Or Sameach implies a distinction between ma'aseh that creates a new status and ma'aseh that is the "origin of the forbidden entity." Planting is the genesis of the tree's existence as an asherah. Therefore, the ma'aseh is not the act of worship, but the act of dedication at the moment of planting. Thus, the tree is born forbidden, unlike an animal that must be "worshiped" (a secondary act) to become forbidden.

Intertext

• Deuteronomy 12:2: "You shall surely destroy all the places... on the mountains, on the hills, and under any luxuriant tree." This is the foundational text for the Rambam's leniency regarding the objects themselves. The Sifrei (ad loc) asks: "Must God cause His world to be destroyed because of the fools?" This provides the metaphysical grounding for the Rambam's logic that the natural world is independent of human folly.
• SA Yoreh De'ah 145:1: The Shulchan Aruch largely adopts the Rambam's stance, but the Rama adds significant caveats regarding the bitul (nullification) of idols owned by Jews, emphasizing the genizah (entombment) requirement, reflecting a more cautious stance on the permanence of the issur.

Psak/Practice

The psak follows the Rambam’s stringent requirement:

1. Ownership is everything: If a non-Jew or a non-owner performs an act of worship on your property, it does not necessarily render the object forbidden for you, provided your own kavanah (intent) remains aligned with halachah.
2. Nullification: A Jew cannot nullify a deity—period. This is a meta-psak heuristic: the Jewish identity is inextricably linked to the negation of idolatry, meaning a Jew’s "reverence" (even if simulated) or "nullification" is ontologically invalid for the object.

Takeaway

The Rambam posits that the natural world is inherently holy/neutral; only human manipulation—specifically when that manipulation asserts a false deity—can "trap" holiness or create issur. Once that trap is set by a Jew, it is a permanent seal; for a gentile, it remains a transient, human-based error.
