Mishneh Torah, Fasts 5

Sugya Map: The Teleology of Commemoration

• Issue: The ontological status of the "Four Fasts" (Zechariah 8:19) post-Temple. Are they mandatory decrees or commemorative customs?
• Nafka Mina: Whether the obligation is chovah (binding) or minhag (customary), affecting stringencies (e.g., Taanit Esther vs. Tish'ah B'Av).
• Primary Sources: Rosh HaShanah 18b; Mishneh Torah, Hilchot Ta'aniyot 5:1–19; Shulchan Aruch, OC 549–558.

Text Snapshot

"וְיִהְיֶה זֶה זִכָּרוֹן לְמַעֲשֵׂינוּ הָרָעִים וּמַעֲשֵׂה אֲבוֹתֵינוּ שֶׁהָיָה כְּמַעֲשֵׂינוּ עַתָּה עַד שֶׁגָּרַם לָהֶם וְלָנוּ אוֹתָן הַצָּרוֹת" (Hilchot Ta'aniyot 5:1).

Nuance: Rambam shifts the focus from the historical event to the present conduct. The fast is not a memorial for the dead, but an admission of continuing culpability. The root t-z-r (trouble) is presented as a causal chain linked to current behavior.

Readings

• Rambam: The fasts are a pedagogical device for teshuvah. If the cause (our wicked conduct) persists, the effect (the tzarot) remains active.
• Ohr Sameach (on 5:11): Analyzes the Tefillin prohibition. While halachically permitted, the custom reflects the status of an onen (mourner before burial). He reconciles the Yerushalmi’s approach: the fast is not just a commemoration, but a state of mourning for a "dead" Temple that awaits the resurrection of the Geulah.

Friction: The "Future-Past" Paradox

Kushya: If these days are meant to be "days of joy" in the Messianic era (Zech. 8:19), why do we invest such heavy halachic energy into the physical mechanics of mourning (rending garments, ashes on the forehead)? Terutz: Rambam (5:19) suggests that negation of the negative is not the goal; transformation is. We mourn precisely because we recognize the "hidden good" within the tragedy. We are not just remembering a past; we are actively waiting for the moment the "field" (the destroyed Temple) is ready to yield its harvest.

Intertext

• Yoma 1a/b: "Every generation in which the Temple is not rebuilt is as if it were destroyed in its days."
• SA, OC 561: Codifies the Rambam’s view on rending garments, balancing the halachah of mourning with the reality of current sovereignty in Eretz Yisrael.

Psak/Practice

The Rambam’s heuristics demand that we view Tish'ah B'Av not as a funeral for history, but as an active evaluation of current communal health. Practice: When encountering the remnants of destruction, the rending is not a performance—it is a visceral reminder that the "heart" of the nation remains exposed until the transformation of the fasts occurs.

Takeaway

The fasts are not an act of looking back, but a diagnostic tool for looking inward; we fast because we are still the generation that hasn't built the Temple.
