Mishneh Torah, Blessings 1

Sugya Map

• Issue: The mechanism of yotzei (discharging obligation) via Amen or shomei’a k’oneh.
• Primary Sources: Berachot 20b, 53b; Mishneh Torah, Hilchot Berachot 1:11–12.
• Nafka Mina: Whether a non-obligated person (e.g., a child or one who has already eaten) can discharge another’s obligation.

Text Snapshot

• MT 1:11: "Anyone who answers Amen to a blessing recited by another person is considered as if he recited the blessing himself, provided the person who recites the blessing is obligated to recite that blessing."
• Nuance: The Rambam insists on chayav (obligation) as a prerequisite for yotzei. Note the dikduk in the Rambam’s demand that the speaker must be "obligated in that blessing" (chayav b'otah berachah).

Readings

1. Kessef Mishneh (1:11): Argues that Rambam derives the chayav requirement from Berachot 20b, noting that the Gemara does not suggest a child could discharge an adult’s obligation simply by the adult answering Amen.
2. Rosh (Berachot 3:13): Maintains that Amen is more powerful than shomei’a k’oneh (listening), and thus one might discharge an obligation by answering Amen even if the speaker is not currently obligated. Rambam rejects this, grounding the power of the blessing in the speaker’s own status.

Friction

Kushya: If the principle is arvut (mutual responsibility), why does Rambam require the speaker to be currently obligated? If all Jews are responsible for one another, the speaker’s status should be secondary to the listener’s need. Terutz: Rambam posits that arvut only activates when the speaker is a bar-chiuv (subject to the law). A blessing recited by someone not obligated is an empty vessel; Amen cannot imbue a non-obligated act with the status of a mandatory mitzvah.

Psak/Practice

The Shulchan Aruch (OC 215:2) follows Rambam: a person cannot discharge an obligation by answering Amen to someone who is not himself obligated. Meta-psak: The efficacy of a blessing is not merely a social agreement but requires the speaker to be tied to the legal reality of the mitzvah.

Takeaway

Amen is not a "magic word" that validates any ritual; it is a legal seal that assumes the underlying act is a valid, binding obligation. Without a chayav speaker, the Amen is structurally orphaned.
