This weeks Torah portion, Sh’mini (Leviticus 9:1-11:47), is all about defining in and out. Starting with a depiction of the first major cultic sacrifice, which leads to God appearing to the whole of Israel, the portion tailspins into the death of Aaron’s sons as punishment for their having offered an unsuitable sacrifice of incense. God forbids the family of the dead any mourning. This scene is immediately followed by the prohibition of alcohol to any of the priests while in the Tabernacle (no sacrificing while drunk!), and the categorizing of animals into pure or impure (kosher or unkosher).
So we’ve got some pretty clear in grouping and out grouping. Aaron’s sons, Nadab and Abihu, are certainly out. But what did they do wrong? The text is really ambiguous. They are accused of having offered God “alien fire.” There are plenty of theories on what this means, but none of them help to clarify our main concern here, which is what is it that makes one part of the in-group.
If we assume that the breaking up of the Torah portions was done with distinct purpose and thematically, the idea that a couple of people in the high priesthood stepping slightly, and possibly only mistakenly, out of line could be so immediately dangerous says a lot about the rest of the portion. Offering something unacceptable or simply not commanded as deadly, grouped together portion-wise with the laying out of the laws of purity of animals might give us a hint at a deeper meaning behind the relation of these two segments. If we are explicitly told here which animals are to be eaten, which animals are not to be eaten, and which animals cause impurity, we may be able to derive a boundary for ourselves based on the qualities that makes these animals kosher or unkosher.
Most of the things that are impure are animals that will eat other things within their same category. Four pawed animals often eat other four pawed animals, birds of prey often eat other birds. Things in the sea without scales and fins are also often carnivorous within their own category. And we all know that pigs will eat anything. Their corpses are treated similarly to that of human corpses by the law, too. So their status can then be seen as similar to us. This animal that has a relationship where it consumes other animals makes them in some way akin to us.
Mary Douglas has pointed out that the animals considered clean are generally ones that are domesticated by humans as food sources, or are closely related to these animals. In this case, we see their purpose within the world as being their identifier. So let us combine these qualities: animals whose actual purpose is feeding us are to be eaten, while those who function is eating other animals are not.
Relationships between eater and eaten are actually interesting when you think about it. Why is it that something is appetizing? How can one account for what one has a taste for? It’s certainly not just that the nutritional value is high. There are plenty of things that I crave to eat that aren’t good for me. And I don’t ever seem to crave something I’ve never tried before. In a way, purpose is similar. How does one figure out one’s purpose? By trying things out, and finding what speaks to you. Many humans have this luxury, but it is arguable that animals do not. Despite what those conniving, tricky folks at Pixar might have us believe, I have the sneaking suspicion that animals don’t really have an issue with a sense of purpose in life. So if an animal’s purpose is decided for it, and the animals whose purpose is service are the kosher ones according to the Torah, then the Torah-described kosher ones of humanity must also be those whose purpose is service.
This then makes a case for the Jew as one whose innate purpose is service. That isn’t to say that those outside of Judaism don’t serve a purpose, it is simply a different one, and one of much greater freedom. There’s nothing wrong with a cougar or a hoopoe. They’re very beautiful animals that have purposes within their own biomes. Should one of these hoopoes decide that a life of service to humanity through the Jewish covenant with God is a beautiful thing, I don’t see what the hoopoe shouldn’t be allowed to join in as well. We Jews, though, like the sheep, goat, bovine, are born into service. We don’t have a choice. Some of us are even born outside of Jewish families and find our way into service as Jews later. What kind of service are we born into? We are born into the service of God, according to the Torah. But as Abraham was promised at the moment Jews point to as the beginning of the everlasting covenant between us and God, we are to be a blessing to all of the nations. And as our prophets told us even before the destruction of the first Temple, it is not that God wants us to make sacrifices, which today is akin to the prayer services and the ritual mitzvot, it is that God wants us to deal with humanity in a righteous way. So our purpose carries us even outside of our biome, into the realm of the universal, as a people meant to bless the world with righteousness.
This may be pie-in-the-sky idealism about what Judaism means, but we are talking about religion and mythology here, so idealism fits. One of the greatest concerns today in Reform Judaism is also the issue of who is in and who is out, as can be seen in this exchange between two rabbinical students about intermarriage. At one point, these two rabbinical students start talking about “ultimate concerns” in regards to Jewish theology when discussing intermarriage, but neither broach the subject of what the ultimate concern of the Jew should be. Maybe with a little more focus on an idealistic ultimate concern as being our defining factor, the ultimate litmus test of our in-group would simply be commitment to our mission to be a blessing to all nations through our covenant.
