Lesson 1 · Introduction and Main Theme — Distinguishing the Holy from the Common
The key to the whole book is chapter 10, verse 10: separate the holy from the common and the clean from the unclean — and then teach that distinction to the people. Across eight lessons the course asks: Who may draw near to God? When may they draw near? And by what way?

This lesson covers Exodus 40:34–35; Leviticus 1:1; 9:23–24; 10:1–11, and surveys the structure of the whole book.
Leviticus is not an easy book. After the narrative of Exodus, it turns into a long series of regulations for sacrifice and purity, through which God himself reveals how he may be approached. Yet within the shape of the canon, this book sits at the exact center of the five books of Moses. Its Hebrew name is simply the book’s first word, meaning “and he called”; the title “Leviticus,” used in English and other languages, comes from the Septuagint.
The theme of the whole book: a holy people. Its core message in one sentence: to obey is better than sacrifice.
That sentence does two things. First, it echoes Samuel’s famous word: “To obey is better than sacrifice, and to heed is better than the fat of rams” (1 Samuel 15:22). Though Leviticus is mostly about offerings, its real aim is the obedience and holiness of the people — it does not stop at ritual itself.
Second, in the Old Testament the word “Torah” means “instruction, teaching,” not merely cold “law.” This matches the charge of Leviticus 10:11 exactly: the priests are to teach the people “all the decrees.” Leviticus is instruction meant to be taught, received, and obeyed, so that a “holy people” may be formed. To bring this book into the teaching ministry of Sunday school is therefore entirely fitting.
The difficulty ordinary readers feel is real: to many people Leviticus is “a very strange book — its language, contents, and rituals look monotonous and formulaic.” But that is precisely the cue to change how we read: the point of this book is not only to be understood but to be entered into and felt. If Sunday school turns Leviticus into a stack of information, it misses what the book itself asks for. Leviticus gave Israel a blueprint for building a life of worship after God’s own heart.
Leviticus speaks a language of ritual, and that carries an expectation opposite to our modern habits: ritual language is not meant to be grasped at first hearing. What passes through life too quickly rarely leaves a mark. The worship Leviticus depicts looks dry, yet in it God teaches us a depth of communion on his own terms — not the splendor our senses expect. The language of ritual calls for repeated practice: pondering what fire, blood, the laying on of hands, and the scapegoat really mean in our life of worship.
Exodus ends with the tabernacle completed and the glory filling it:
This is the climax of the Sinai covenant — God really has “moved in” to dwell among his people. Yet the same passage shows the actual situation: in the midst of the glory, Moses the mediator “could not enter the tent of meeting.” Leviticus picks up the scene with its very first sentence:
God now speaks “from the tent of meeting” — he is already inside. And so the book’s central question surfaces: if the holy God now dwells in the middle of the camp, how can a chosen yet sinful people, so easily defiled, draw near to him and live with him without being destroyed?
The sacrificial and purity regulations of Leviticus are the instruction that grew up around precisely this question.
The turn from Exodus 40 to Leviticus 1:1 can be put very plainly: God has moved house. The pattern at Sinai was this: he was up on the mountain, appearing in fire and overwhelming sound; the people were terrified, no one could come near — whoever did would not live. Once the tabernacle was finished, the situation changed: this God is no longer a God who dwells on a mountain. He has become a God who pitches a tent and wanders with Israel wherever they go — and this is his own desire.
The value of this way of putting it is that it holds two things together. God’s presence truly has come closer — down from the summit into the middle of the camp; and yet the thing that makes approach impossible has not changed at all. The tabernacle is built layer upon layer: innermost, the Most Holy Place, with the ark, the two cherubim, and between them an empty seat — the throne of God; around it the Holy Place, then the courtyard, then the camp of the Levites, and outermost the twelve tribes. Since God dwells at the exact center of the camp, the entire space is ranked by distance from him. This is Leviticus 10:10’s “separating the holy from the common” in spatial form — and it gives the theme of the throne of the King a footing in text and space from the very start.
The altar at the entrance of the tent has its own place in this arrangement. One common reading: once God had hidden himself within, that fire now burns at the doorway of the tabernacle — and it stands for an invitation. The fire on Sinai that cost people their lives has been gathered onto the altar at the entrance — the same fire; what changed is its place and its function. This also warns us against a domesticated view of God: the theology of our day likes to tame this God into something like a Santa Claus. In truth, one who can “blaze out” dwells permanently in the Most Holy Place — he is not to be treated lightly or despised.
A second frame ties the tabernacle back to the stories of the patriarchs: the sanctuary is the point where heaven and earth meet. Three meeting places can be named — Abraham at the great tree of Moreh (Genesis 12:6–7), Isaac at Beersheba (Genesis 26:23–25), and Jacob at Bethel, where he saw the stairway joining heaven and earth (Genesis 28:12). From these we may conclude: an essential meaning of the sanctuary is that it is the meeting point of heaven and earth; that center point is the center of heaven and earth — the wellspring of life.
Put this together with the “move,” and the question of Leviticus becomes still clearer: God has planted the meeting point of heaven and earth in the middle of Israel’s camp. “How do we draw near?” is therefore a practical question of holy order — and the regulations of the whole book are the answer to that question.
Leviticus 16 (the Day of Atonement) stands at the center of the book — preceded by sacrifice and cleansing, followed by the call to holy living — and so is often regarded as the hinge of the whole.
Leviticus 8–9 recounts the climax of the priests’ ordination. After Aaron offers the first sacrifices —
Fire from God, the offering accepted — a moment of glory. Immediately afterward the narrative turns, in almost identical words:
Both times “fire came out from the presence of the Lord” — a moment ago it brought shouts of joy; now it brings death. The contrast confirms the thesis that to obey is better than sacrifice: Nadab and Abihu were not failing to sacrifice — they sacrificed on their own terms, not as God had commanded, and the holy fire broke out from the throne. The key phrase is “unauthorized fire” — literally “strange, alien fire”: fire God had not commanded, foreign to the order of the sanctuary. The “strange/common” stands opposed to the “holy”: they carried what did not belong to the sanctuary into the holiest place, and so blurred the boundary. Moses at once states the weight of it in God’s own words:
Right after the tragedy, God himself speaks to Aaron and gives the priests their charge:
The verb behind “distinguish” means “to separate, to divide.” It is the very word Genesis 1 uses again and again for God’s creating: God “separated” light from darkness, the waters above from the waters below, day from night (Genesis 1:4, 6, 7, 14, 18). The shared vocabulary is no accident: when the priests separate holy from common and clean from unclean in the sanctuary, they echo the separating by which God ordered creation. To blur the boundaries is to run against creation itself — back toward chaos. From this we may infer: the purity system of Leviticus is a form of participation in upholding the created order, regulating how a person draws near to God according to God’s own order.
Leviticus 10:10 lays out two pairs of opposites — four terms (in the verse’s own order):
The priestly office therefore has two sides: to draw the boundary (10:10), and to teach the people to recognize it (10:11). That “separate” and “teach” stand side by side is also the warrant for Sunday school itself — teaching brothers and sisters how to serve in the house of God. Torah is instruction; Torah is teaching.
A widely cited diagram fills out the picture: every person, thing, and time stands in one of three zones — holy, clean, or unclean. “Sanctify/profane” links the holy and the clean; “cleanse/defile” links the clean and the unclean. It makes visible the directed movement of the Levitical system: from common to holy, from unclean to clean — so that the people may draw near and the glory may remain. One common proposal adds that ritual impurity is, at its core, bound up with death.
In Leviticus, “holy” means first of all belonging: set apart by God, belonging to God. Vessels, days, priests, and the people are called holy because God has set them apart from ordinary use for himself. So the primary meaning of holiness is a given identity — “belonging to God” — followed by the calling to live worthily of it. On this rests the book’s repeated command, “Be holy because I, the Lord your God, am holy” (Leviticus 19:2; cf. 11:44–45) — which is exactly what “a holy people” means.
“Clean,” by contrast, names a state: through death, disease, childbirth, or certain contacts a person enters impurity for a time — mostly symbolic rather than moral guilt. Leviticus provides the way back from uncleanness to cleanness, to regained nearness. The whole book thus moves toward one goal: dwelling with God.
The boundaries drawn in Leviticus are carried to their fulfillment in Christ. This first lesson sets the master link: the foundational command, “Be holy, because I ... am holy” (Leviticus 19:2), is taken over whole by Peter as the basis of the believer’s life (1 Peter 1:15–16). Romans — this course’s guide to that “fulfillment” — opens by placing every person inside Leviticus’s question: how can anyone be counted clean and accepted before the holy God?
And near its close the letter urges believers “to offer your bodies as a living sacrifice, holy and pleasing to God” (Romans 12:1) — the very vocabulary of sacrifice and holiness from Leviticus, answering from afar the theme of being offered as a living sacrifice.
