The last several mishnahs in our chapter have explained that slaughtering an animal for idolatry invalidates the slaughter. A mishnah on today’s daf discusses how to avoid even the appearance that one is slaughtering in the name of an idol. This helps transition to the last mishnah in our chapter, also on today’s daf, which discusses a very different sort of intent:
One who slaughters an animal for the sake of a burnt offering, for the sake of a peace offering, for the sake of a provisional guilt offering, for the sake of a paschal offering, or for the sake of a thanks offering — his slaughter is not valid. But Rabbi Shimon deems his slaughter valid.
Whereas the previous mishnahs were concerned with what happens if one slaughters an animal intended for ordinary consumption in the name of an idol, this mishnah is concerned with intent to slaughter non-sacred animals for the purpose of a Temple sacrifice. If I’m standing in my courtyard slaughtering a lamb for dinner, but I hold in my mind the intention that it become a peace offering, that invalidates my act. I’m not allowed to eat that lamb — according to everyone except Rabbi Shimon.
Rashi explains that this ruling is a gezeirah (decree) of the rabbis. On a Torah level, since this animal was not sanctified, intent to slaughter it for an offering has no impact — the meat should be kosher. The rabbis, however, decreed it forbidden, lest one observing this action comes to think sanctifying and slaughtering outside the Temple is now permissible. This is a classic case of marit ayin, literally “the appearance of the eye,” where the rabbis forbid something that’s not inherently problematic because it could lead others to mistaken assumptions — in this case, the mistaken assumption that you can slaughter a peace offering in your own courtyard. This is absolutely forbidden; no sacrifice is permissible outside of the Temple.
The mishnah continues:
One who slaughters an animal for the sake of a sin offering, for the sake of a guilt offering for a definite transgression, for the sake of the offering of a firstborn, for the sake of the offering of animal tithe, or for the sake of a substitute for a sacrificial animal — his slaughter is valid.
If one intends to slaughter an animal for one of the offerings listed here, everyone agrees the animal is permissible. What makes this set of sacrifices different than those in the first clause, which were disqualifying? The final clause of the mishnah helps elucidate the rationale:
This is the principle: For any item (i.e., offering) which is consecrated as a voluntary vow or gift, in the case of one who slaughters for its sake, the animal is forbidden. And for any offering that is not consecrated as a voluntary vow or gift, one who slaughters for its sake the animal is permitted.
The difference is whether the animal is being slaughtered in the name of a voluntary offering or a required offering. Why is this significant? Rashi explains that your neighbors know what offerings you are obligated to bring and what offerings you are bringing voluntarily. If you slaughter an animal in your courtyard in the name of an obligatory offering, others would be aware that you are not actually under the obligation to bring that sacrifice; therefore, they wouldn’t be led to the mistaken assumption that sacrifice outside the Temple is permissible — because they would intuit that you are not operating within the normative bounds of halakhah. By contrast, if you slaughter an animal as a voluntary offering in your courtyard, this rationale no longer holds, and your neighbors might intuit that it is a real sacrifice and, therefore, mistakenly conclude that one is really allowed to slaughter a sacrifice at home.
The debate over marit ayin here is interesting, in that it assumes certain information and rules are definitely known by the casual observer, but with regard to others, they could easily be misled. There are two main things at play here: knowledge about your neighbors’ actions and knowledge about the law. The rabbis generally assume that many sins generate publicity, such that if a person says they’re bringing a sin or guilt offering and no one knows them to have committed that offense, it will be clear that this is simply not in accordance with the halakhah.
On the other hand, we have to assume people’s knowledge of the law is shaky enough that they might mistakenly believe voluntary offerings outside the Temple are now permitted. Arguably the main distinction here is between what we assume people to already know about the existing law — i.e., a sin offering is only brought when a person has done a specific sin — versus what we assume people know about evolutions of the law. In this case, the concern is that your average layperson might think that the law has evolved to permit sacrifices outside the Temple — which, in fairness, was at one point in time permitted. So even though the rabbis’ ruling does rely on a somewhat mixed assessment of how much legal and factual knowledge people possess, one can understand the room for concern.
