This is part of our “Leviticus for the Modern Reader” series, focusing on themes that God’s people today can take away from what is typically seen as a dry and perplexing book. You can read the previous ones on burnt offerings, spiritual nakedness and clothing, and spiritual leprosy here.
If you’ve ever read Leviticus, you know that in chapter 11 God gives Moses a long and detailed accounting of what animals are allowed to be eaten or touched, and which are not. He calls the prohibited animals “unclean”, and says they are an abomination. He also prohibits eating the blood and fat of an animal being sacrificed. These food-focused scriptures are where we’ll focus today.
Even for people who love reading their bible, Leviticus can be a tough book to connect to. It’s effectively a comprehensive instruction manual for Israel’s priesthood, filled with blueprints, detailed societal rules, the process for various sacrifices, and purification rituals.
It’s logical to wonder why it was included in the bible, or to chalk it up to a dry-but-interesting historical record and move on, thinking “Welp, glad it doesn’t apply to me today!” While those are understandable reactions, we know that everything in the bible is there for a reason, and that all scripture is God-breathed and given to us for our education, inspiration, and growth (II Tim. 3:16).
So what should we make of these seemingly-random dietary laws in Leviticus?
If we pull back and look take a 30,000-foot view, Leviticus is ultimately a book about holiness and sanctification—what it means to be set apart by God for a purpose. God was showing His newly-established nation what it means to worship a holy God, for Him to dwell with them, and be in relationship with Him. He continually tells them, “You shall be holy for I, the Lord your God, am holy” (Lev. 19:2).
In previous posts we examined what Christians today can learn from the burnt offerings and rules about clothing and nakedness. In this study we’ll dive into what Leviticus says about what we put IN our bodies—what God prohibits us from consuming, and what the bible tells us about our spiritual diet.
This focuses on one of the passages in Leviticus that I believe does have literal application to our lives today, and we’ll start there. First we’ll look at what Leviticus commands about what we eat and whether it is still a command for modern Christians. But stick with me, we’ll then dive more into what the bible tells us about our spiritual food and drink, and why what we put into our body (spiritually) matters.
“They are unclean to you…”
Let’s start in Leviticus 11:2. It’s a long chapter so we’ll skim through and hit some high points. God tells Moses, “Speak to the children of Israel, saying, ‘These are the animals which you may eat among all the animals that are on the earth…” Here are the cliff notes:
- God tells the Israelites that they CAN eat animals that chew the cud and have divided hooves, fish that have fins and scales, a couple insects (locusts, crickets, and grasshoppers), and then prohibits a whole list of very specific birds (with the implication that anything outside that list is okay).
- In each section about the unclean animals, he specifies some version of “their flesh you shall not eat, and their carcasses you shall not touch. They are unclean to you” (Lev. 11:8).
- A few verses later when speaking of sea creatures, He reiterates, “But all in the seas or in the rivers that do not have fins and scales…they are an abomination to you. They shall be an abomination to you; you shall not eat their flesh, but you shall regard their carcasses as an abomination” (Lev. 11:10-11).
- He uses similar language as He goes through birds and winged insects, as well as later in the chapter referring to creeping things (reptiles, for instance).
The Israelites are warned that if they ate any of these unclean animals, or if the dead bodies came into contact with them or their belongings, it made them unclean (Lev. 11:24-28, among other verses). Why does God spend almost fifty verses on this topic?
“You shall not make yourselves abominable with any creeping thing that creeps; nor shall you make yourselves unclean with them, lest you be defiled by them. For I am the Lord your God. You shall therefore consecrate yourselves, and you shall be holy, for I am holy.
Neither shall you defile yourselves with any creeping thing that creeps on the earth. For I am the Lord who brings you up out of the land of Egypt, to be your God. You shall therefore be holy, for I am holy. This is the law of the animals and the birds and every living creature…to distinguish between the unclean and the clean, between the animal that may be eaten and the animal that may not be eaten” (Lev. 11:41-47)
The easiest answer to why this is commanded is, “because God said so”. In terms of why those specific animals are forbidden, there are a number of schools of thought—including health reasons, as well as animals that were frequently worshipped and eaten by the pagan societies around them. (I do believe there is a strong case to be made for both of those, for what it’s worth.) Ultimately, we can’t be sure what specific reason God had for making the distinction beyond it being His choice, but that’s all that matters.
Leviticus is packed with rules about what makes someone or something “unclean”. This designation is generally a ritual impurity rather than a sin, and requires temporary separation from God’s tabernacle and rituals (usually washing) to come back into contact with holy spaces. Most of the “unclean” rules were part of daily life, such as having sex, childbirth, a woman’s period, or certain diseases.
There are, however, two things that make the dietary laws in Leviticus largely unique—and they should make us sit up and take notice.
