A particular excerpt from Leviticus 21 mentions an exception to the sons of Aaron who are permitted to participate in the giving of food offerings to Yahweh: a man who is physically disabled. Not all disabilities are outwardly evident or have to do with the body, but the kinds described in this chapter are. Does the Torah disregard or dehumanize the disabled here? I myself would be unable to perform the food offering, though my physical disability is one that I can forget about because it is so relatively minor. There is nonetheless nothing oppressive in this case. The passage says enough to indicate what it does not directly or by logical extension require, and there is more to the Bible on the ethics of how to treat the disabled than this. Here is the passage:
Leviticus 21:16-23--"The Lord said to Moses, 'Say to Aaron: "For the generations to come none of your descendants who has a defect may come near to offer the food of his God. No man who has any defect may come near: no man who is blind or lame, disfigured or deformed; no man with a crippled foot or hand, or who is a hunchback or a dwarf, or who has any eye defect, or who has festering or running sores or damaged testicles. No descendant of Aaron the priest who has any defect is to come near to present the food offerings to the Lord. He has a defect; he must not come near to offer the food of his God. He may eat the most holy food of his God, as well as the holy food; yet because of his defect, he must not go near the curtain or approach the altar, and so desecrate my sanctuary. I am the Lord, who makes them holy."'"
From these verses alone, several vital points are clarified. First, the scope is rather limited, pertaining to nothing more than the offering of devoted food to God and the related act of approaching a specific curtain and altar. This is not matter from which it follows by logical necessity that the deformed Levite man must be tossed aside or keep himself away from all Levitical activity. Moreover, the passage itself explicitly permits them to still eat from the offerings to Yahweh, which are allowed to the priests. All that it actually forbids is the very precise action of giving food offerings to God or approaching the curtain or altar to do so. The ideas behind this passage are quite far from dehumanizing the disabled or prescribing any sort of systematic segregation, barring from professional labor, or interaction with the full-bodied.
In the very same book of Leviticus, though, there is a verse which condemns mistreatment of the disabled, providing two non-exhaustive examples similar to what Exodus 21:26-27 does with the physical abuse of male and female slaves which entitles them to emancipation. In fact, reading through the book in chronological sequence would take one to the verse prohibiting the oppression of the disabled before one arrives at Leviticus 21:16-23, which I again emphasize is strictly about the Levitical priesthood and has nothing to do with treatment of the disabled in a broader sense. Also, among the declarations in Deuteronomy 27 about how people who commit miscellaneous sins are cursed, other examples being dishonoring one's father or mother (27:16), bestiality (27:21), and killing an innocent person for a bribe (27:25), there is a similar statement in favor of the rights of the disabled.
Leviticus 19:14--"'"Do not curse the deaf or put a stumbling block in front of the blind, but fear your God. I am the Lord."'"
Deuteronomy 27:18--"'Cursed is anyone who leads the blind astray on the road.' Then all the people shall say, 'Amen!'"
The Bible clearly does not in any way teach that disabled men and women are subhuman, unworthy of a spiritual relationship with God, or deserving of societal exclusion or neglect. On the contrary, Mosaic Law affirms their humanity and calls anyone who would take advantage of them cursed. The restrictions of Leviticus 21 are exclusively for the administration of specific priestly obligations that parallel how the animals to be sacrificed were also to, with some exceptions (Leviticus 22:23), be entirely unblemished (Leviticus 1:3, 10, 3:1, 6, 4:1, Deuteronomy 15:21, 17:1, and so on). All people are still made in the image of God on Judeo-Christianity (Genesis 1:26-27, 5:1-2), whatever their bodily status, be they sons of Aaron from distant generations or the mute, blind, or quadriplegic men and women of today.
