A Complete Bible Study on The Role of the High Priest

Main Question

What did the high priest do, and how does that office point to Jesus Christ as our sinless, eternal High Priest?

Primary Passages

Exodus 28-29, Leviticus 8 and 16, Leviticus 17:11, Psalm 110, Hebrews 4, 7, 9, and 10.

Unforsaken Conclusion

God appointed the high priest to teach Israel about holiness, mediation, blood atonement, and access to God. Jesus is the fulfillment who offered Himself once for all.

Opening the Question

Leviticus can feel far away from modern life because it speaks about priests and their garments. It describes their consecration and service at the altar. Incense and blood appear throughout the ceremonies, while veils create careful boundaries within the tabernacle. Yet God did not fill Scripture with ancient ceremony for its own sake. He was teaching His people the seriousness of sin and the perfection of His holiness. Sinners may draw near to Him only through the way He appoints.

The high priest stood at the center of this lesson. He represented Israel before God by wearing the names of the tribes and offering the required sacrifices. On the Day of Atonement, he entered the most holy place with blood. His ministry was real and necessary because God commanded it under the Law. However, it was never meant to be final but pointed forward to something greater.

The New Testament, especially Hebrews, teaches that Jesus Christ is the great High Priest. He is not merely a slightly better Aaron. He is the sinless Son of God who became truly man. As the one Mediator between God and men, He holds an eternal priesthood after the order of Melchizedek. He entered the true heavenly sanctuary by His own blood. Instead of offering an animal, He offered Himself. He did not repeat the sacrifice. He offered one sacrifice for sins forever and sat down at the right hand of God.

This study matters because many believers carry guilt as though the veil were still hanging shut. Others treat worship lightly, as if sinful people could approach God on whatever terms they prefer. The priesthood answers both errors. God is holy, and sin requires blood atonement. The way to Him has been opened only through Jesus Christ.

Passages You Will Need to Study

The role of the high priest cannot be understood from one verse alone. Exodus explains the priestly garments and consecration, while Leviticus describes the sacrificial system and the Day of Atonement. Psalm 110 announces a priest who will remain forever. Hebrews then explains how these promises and patterns are fulfilled in Christ. Together, the passages give one unified testimony. The old priesthood was a God-given shadow, and Jesus is its substance.

Priestly Appointment

Exodus 28-29 and Leviticus 8 show that God appointed Aaron and his sons. He commanded that they be washed and clothed for ministry. They were then anointed and consecrated for His service.

Atonement Pattern

Leviticus 16 describes the Day of Atonement and the blood brought to the mercy seat. Chapter 17 explains the substitutionary purpose of blood as God’s provision for guilt.

Greater Priesthood

Psalm 110 and Hebrews 7 show that Christ’s priesthood is forever and is according to the order of Melchizedek.

Finished Sacrifice

Hebrews 4 reveals Christ’s sinless sympathy toward human weakness. Chapters 9 and 10 explain how He entered by His own blood and made a once-for-all offering. His finished work gives the believer bold access to God.

God Appointed the Priest

The priesthood was not Israel’s religious invention. Aaron did not seize the office, and Moses did not design a ministry structure from human imagination; God commanded it. That teaches us first that sinners do not create their own access to God. The Lord sets the terms of approach because He is holy and because mercy must be given in truth.

And the LORD spoke to Moses, saying: “Take Aaron and his sons with him, and the garments, the anointing oil, a bull as the sin offering, two rams, and a basket of unleavened bread;”

Leviticus 8:1-2

Notice how much God supplies within this command. He identifies the priest and provides his garments along with the anointing oil. God also requires the sin offering and the rams, as well as the bread used in the consecration. Before Aaron can minister, every necessary element comes from the Lord. The mediator and sacrifice exist by God’s appointment. This pattern points forward to the gospel, where God provides both in His own Son.

Exodus says that the priests were to be hallowed for ministry, which means they were set apart for God’s service. This language does not mean that Aaron became sinless. He remained a sinner who needed sacrifice even after his consecration. Jesus is different because He is holy in Himself and entirely without sin. He is therefore qualified to save in a way Aaron never could.

“And this is what you shall do to them to hallow them for ministering to Me as priests: Take one young bull and two rams without blemish,”

Exodus 29:1

The animals had to be without blemish because God was teaching Israel that guilt could not be handled through a polluted substitute. Sin deserves death, so the substitute offered under God’s command had to be clean. These sacrifices did not finish redemption. They proclaimed God’s holiness and the deadly seriousness of sin while teaching that blood atonement is necessary.

Word Examinationqadash

Hebrew

Meaning

to set apart, hallow, consecrate

The consecration language marks the priests as set apart for God’s service. It does not erase Aaron’s personal need for atonement, which is why the old priesthood could only point toward the sinless Priest to come.

The Tabernacle Taught a Boundary

The tabernacle itself preached through its design. A worshiper first entered the outer court, while only the priests ministered in the holy place. The most holy place stood behind a further barrier. Access became more restricted as a person approached the place of God’s special presence. This was not cruelty but a truthful witness to God’s holiness. He was present with His people, yet sinners could not rush into His presence on their own terms.

The mercy seat stood over the ark of the covenant, behind the veil. God promised to meet with Israel there.

You shall put the mercy seat on top of the ark, and in the ark you shall put the Testimony that I will give you. And there I will meet with you, and I will speak with you from above the mercy seat, from between the two cherubim which are on the ark of the Testimony, about everything which I will give you in commandment to the children of Israel.

Exodus 25:21-22

The mercy seat and the veil belong together. The mercy seat declares that God desires to dwell among His people and speak to them. The veil declares that sin has created a real barrier. The Bible does not let us choose one truth and discard the other. God is merciful, and God is holy.

This is why sentimental views of worship fail. Drawing near to God is not casual access to a divine mood of kindness. It requires atonement. The old covenant gave Israel a true but temporary pattern. The new covenant gives the fulfillment in Christ.

Shoulders and Heart

The high priest’s garments were visual theology rather than a display of fashion or human status. Through them, God taught Israel how the priest represented the nation before Him. Their design spoke of holiness and judgment while displaying the beauty God appointed for worship. They also pictured the burden the priest carried. Aaron therefore entered as the appointed representative of the people rather than as a private man.

The names of Israel were engraved on two onyx stones and placed on the shoulders of the ephod.

“Then you shall take two onyx stones and engrave on them the names of the sons of Israel: six of their names on one stone and six names on the other stone, in order of their birth. With the work of an engraver in stone, like the engravings of a signet, you shall engrave the two stones with the names of the sons of Israel. You shall set them in settings of gold. And you shall put the two stones on the shoulders of the ephod as memorial stones for the sons of Israel. So Aaron shall bear their names before the LORD on his two shoulders as a memorial.”

Exodus 28:9-12

Shoulders speak of bearing a load. Israel’s names were carried before the LORD by the priest God appointed. The people were not forgotten. Their tribes were represented before God in the place God commanded.

The breastplate brought the picture even closer. The names were over Aaron’s heart when he went into the holy place.

“So Aaron shall bear the names of the sons of Israel on the breastplate of judgment over his heart, when he goes into the holy place, as a memorial before the LORD continually.”

Exodus 28:29

There is both strength and tenderness in the picture of the shoulders and the heart. The priest bears the people before God in a way that displays care. Yet Aaron’s representation remains limited because he can only carry their names into an earthly sanctuary. He cannot cleanse the conscience forever. Jesus carries His people in a greater way through His finished work and perfect righteousness. He also represents them through His living intercession.

What This Establishes

The high priest represented the people before God. That representation was real, but it was a shadow of the perfect representation believers have in Jesus Christ.

Blood and Atonement

The sacrificial system centers upon a truth that modern people often resist: sin deserves death. God never taught Israel that sincerity could heal guilt. Neither ceremony nor self-improvement could accomplish that work. He gave blood upon the altar to make atonement.

For the life of the flesh is in the blood, and I have given it to you upon the altar to make atonement for your souls; for it is the blood that makes atonement for the soul.

Leviticus 17:11

The wording is crucial because God says, “I have given it to you.” Israel did not bribe God into mercy; God provided the blood atonement He required. The sacrifices were commanded by God and accepted in their covenant setting, yet they pointed beyond themselves because animal blood could not finally remove sin. It taught the need for a better sacrifice.

The Hebrew atonement language has the idea of covering or dealing with guilt in the way God accepts. That must never be made vague. The covering was not God pretending sin did not exist. The life of the flesh is in the blood, and blood was given on the altar. Sin was being addressed through substitutionary death under God’s command.

Christ’s blood therefore cannot be treated as poetic decoration. Jesus physically bore the punishment for our sins in His innocent body. Wicked men caused Him to suffer and shed His blood before they killed Him. He then rose bodily from the dead. The old sacrifices pointed toward Him, but His sacrifice actually accomplishes eternal redemption.

Word Examinationkaphar

Hebrew

Meaning

to cover, make atonement

In Leviticus, atonement is tied to God’s appointed blood provision. The word should be explained in its sacrificial setting, then carried forward to Christ’s greater and final blood atonement.

The Day of Atonement

The clearest picture of the high priest’s role appears on the Day of Atonement in Leviticus 16. Once each year, he entered the most holy place and never did so without blood. He first had to offer for himself because he was also a sinner. Only then could he make atonement for the people according to God’s command.

Hebrews looks back at that annual ministry and explains the pattern.

But into the second part the high priest went alone once a year, not without blood, which he offered for himself and for the people’s sins committed in ignorance;

Hebrews 9:7

That verse carries several lessons. The high priest went alone because access was restricted, and he went only once a year because the way had not yet been opened in fullness. He entered with blood because sin required atonement, and he offered for himself as well as for the people because the old mediator also needed mercy.

Leviticus 16 also includes two goats. One is killed as the sin offering, while the other is sent away into the wilderness. Together, they teach both atonement and removal. Sin must be dealt with before God, after which guilt is pictured as being carried away from the people. The ceremony presents a vivid and serious expression of God’s mercy.

Yet repetition was built into the calendar as the day returned year after year. This was not a failure of God’s instruction, but part of the instruction itself. If the old sacrifices had perfected the worshipers forever, they would have ceased, so their repetition declared that something better was still needed.

The Old Priesthood Had Limits

The old priesthood was holy because God appointed it, but it remained limited. Its priests were sinners who eventually died and had to be replaced. They ministered within an earthly sanctuary and repeatedly offered sacrifices. Their work pointed toward cleansing without finally cleansing the conscience.

For the law, having a shadow of the good things to come, and not the very image of the things, can never with these same sacrifices, which they offer continually year by year, make those who approach perfect.

Hebrews 10:1

A shadow is connected to something real, so the Law’s priesthood was neither meaningless nor empty ritual. It was God’s own teaching pattern, but the shadow was not the substance. Christ Himself is the substance to which it pointed.

This distinction keeps us from two opposite mistakes. We should not despise Leviticus as irrelevant, because God wrote it to teach us. We should also refuse to return to an unfinished priestly system as though Christ’s sacrifice needed earthly repetition. The old priesthood pointed forward, and Jesus fulfills everything to which it pointed.

The Order of Melchizedek

Hebrews does not present Jesus as a priest from Aaron’s line. Jesus is from the tribe of Judah, and His priesthood is of a higher order. Psalm 110 announced it long before the book of Hebrews explained it.

The LORD has sworn And will not relent, “You are a priest forever According to the order of Melchizedek.”

Psalm 110:4

Melchizedek appears in Genesis 14 as king of Salem and priest of God Most High. He blesses Abram, and Abram gives him a tenth. Hebrews uses that scene to show the superiority of Melchizedek’s priesthood over Levi, because Levi was still in Abraham in the argument. The lesser is blessed by the greater.

In the established Unforsaken understanding, Melchizedek is a Christophany, which means a pre-incarnate appearance of Christ. The description in Hebrews fits this weight. Melchizedek is the king of righteousness and the king of peace. Scripture supplies no father or mother for him and gives no genealogy. It presents neither the beginning of his days nor the end of his life, and it says that he was made like the Son of God. These details are not given to make Melchizedek a curiosity but to magnify the eternal priesthood of Christ.

For the priesthood being changed, of necessity there is also a change of the law.

Hebrews 7:12

If the priesthood changes, the law tied to that priesthood changes. Christians do not continue the Levitical system with new language. We come through the Priest God has appointed forever: Jesus Christ.

Aaronic Order

Repeated and Temporary

Many priests served within the earthly sanctuary. Each one eventually died and had to be replaced while the sacrifices continued to be offered.

Melchizedek Order

Forever in Christ

Jesus holds an unchangeable priesthood and saves to the uttermost those who come to God through Him.

Christ the Great High Priest

Hebrews calls believers to hold fast because we have a great High Priest. The word “great” is not ornamental. Jesus is greater than Aaron and the earthly tabernacle in which he ministered. He is also greater than every repeated sacrifice and every earthly mediator.

Seeing then that we have a great High Priest who has passed through the heavens, Jesus the Son of God, let us hold fast our confession.

Hebrews 4:14

The earthly high priest passed through a veil into a room made with hands. Jesus passed through the heavens. His priestly ministry is anchored in the true presence of God. He is Jesus, truly man. He is the Son of God, truly divine. That is why He can represent us and bring us to God.

For there is one God and one Mediator between God and men, the Man Christ Jesus,

1 Timothy 2:5

There is one Mediator, which is good news for guilty people. Your access to God is not divided between Christ and your recent spiritual performance. You never come partly through Jesus and partly through your own record. You come entirely through Him.

Jesus is also able to sympathize with weakness. His sinlessness does not make Him cold; it makes Him qualified. A fellow sinner cannot rescue sinners from sin, but the sinless Savior can.

For we do not have a High Priest who cannot sympathize with our weaknesses, but was in all points tempted as we are, yet without sin.

Hebrews 4:15

Then Hebrews draws the pastoral conclusion.

Let us therefore come boldly to the throne of grace, that we may obtain mercy and find grace to help in time of need.

Hebrews 4:16

Boldness is not irreverence, but open confidence through the Priest whom God has provided. The believer comes because Christ has opened the way, finding mercy for failure and grace for weakness.

The Veil Opened

At the death of Jesus, the temple veil was torn from top to bottom. The direction matters. Man did not climb into God’s presence. God opened the way through the death of His Son.

Then, behold, the veil of the temple was torn in two from top to bottom; and the earth quaked, and the rocks were split,

Matthew 27:51

Hebrews explains the meaning for believers. We have boldness to enter the Holiest by the blood of Jesus, through a new and living way.

Therefore, brethren, having boldness to enter the Holiest by the blood of Jesus, by a new and living way which He consecrated for us, through the veil, that is, His flesh,

Hebrews 10:19-20

The way is new because the old order has been fulfilled, and it is living because Christ has risen. Hebrews says that this way passes through the veil of His flesh because His body was truly given. It is opened by His blood because atonement is not merely an idea. It is the finished work of the Son of God, who died for sinners and rose again.

Hebrews then says to draw near with a true heart in full assurance of faith. Full assurance is not pride. It is taking God at His word about His Son. Many believers keep measuring their access by how they performed this week. Hebrews directs the conscience to Christ’s blood.

let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience and our bodies washed with pure water.

Hebrews 10:22
The Implication

A believer’s confidence before God rests upon Christ’s blood rather than upon his present mood or memory. No ritual can provide this confidence, and recent spiritual success cannot create it. The veil is torn because Jesus finished the work.

He Lives to Intercede

Christ’s sacrifice is finished, and His priestly care continues. Hebrews says He is able to save to the uttermost because He always lives to make intercession for those who come to God through Him.

Therefore He is also able to save to the uttermost those who come to God through Him, since He always lives to make intercession for them.

Hebrews 7:25

Intercession does not mean that the Son is begging an unwilling Father to be kind. The Father sent the Son, who willingly gave Himself. The Spirit applies His finished work because God is united in salvation. Christ’s intercession is His ongoing priestly representation of His people before God upon the basis of His completed sacrifice.

John adds the language of advocacy. When believers sin, they do not need to pretend that nothing happened or hide from the truth. Neither do they need to despair. They have an Advocate with the Father, Jesus Christ the righteous.

My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous. And He Himself is the propitiation for our sins.

1 John 2:1-2

John does not write so that believers will treat sin lightly. He writes so that they may not sin. Yet when a believer sins, the answer is not condemnation as the final word. The answer is Christ the righteous, the propitiation for our sins. Propitiation means His sacrifice satisfies God’s righteous judgment against sin. Sin is not ignored. It is dealt with in Christ.

John also preserves the whole-world scope of Christ’s provision in the rest of the verse. Jesus died for all. His sacrifice is sufficient for all, and the offer is genuine. Those who come to God through Him are saved to the uttermost.

The Believer’s Priesthood

The New Testament calls believers a holy priesthood, but this does not mean that Christians offer sacrifices for sin. Christ’s sin offering is finished. Because they have received mercy, believers offer their worship and praise through Jesus Christ. Their service and generosity rise through Him as well, along with their prayers and daily obedience.

you also, as living stones, are being built up a spiritual house, a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ.

1 Peter 2:5

The phrase “through Jesus Christ” guards the whole idea. The believer’s priesthood is not independent access based on personal worthiness. It is access through the one Mediator. We come to God because Christ has brought us near. We serve because He has cleansed us. We worship because His blood has opened the way.

This also means that no earthly priest or pastor can repeat Christ’s sacrifice or stand as a second mediator for sin. No church or ritual can do so either. Church leaders may teach and shepherd God’s people, and they may pray as they administer the ordinances. However, none of this completes atonement. Baptism is a precious act of obedience, while communion keeps Christ’s sacrifice before the church in remembrance. Neither ordinance repeats the cross because Jesus’ sacrifice was offered once for all.

Common Errors About the High Priest

Common Error

Treating Leviticus as Useless

The priesthood was God’s instruction. It teaches holiness, mediation, sacrifice, atonement, and the need for Christ.

Common Error

Returning to Earthly Mediators

There is one Mediator between God and men, the Man Christ Jesus. No earthly system can repeat or complete His priestly work.

Common Error

Weakening the Blood

Atonement is not vague inspiration. Christ shed His blood, bore the punishment for our sins, died, and rose again.

Common Error

Confusing Access With Casualness

Believers draw near boldly through Christ, yet never lightly. The price of access was the blood of the Son of God.

How This Should Shape Us

First, the high priest should make us reverent. God is holy. The old covenant did not treat worship as human self-expression. Every boundary, garment, washing, sacrifice, and entry into the sanctuary taught that sinful people need mercy on God’s terms.

Second, the high priest should make us grateful for Christ’s blood. Leviticus 17:11 says God gave blood on the altar to make atonement. Hebrews says Christ entered by His own blood, having obtained eternal redemption. The cross is not a vague sign of love. It is the place where Jesus bore our sins and gave His life.

Third, this should give believers settled confidence. If you are in Christ, you do not stand outside the veil hoping that your recent obedience is enough, but draw near through the blood of Jesus. You can confess sin honestly, receive mercy, and find grace to help in time of need.

Fourth, this should protect the church from false mediation. No preacher, priest, sacrament, ceremony, or institution can take the place of Jesus Christ. Faithful ministry points to Him. False ministry competes with Him.

Finally, this should make worship responsive. Believers offer spiritual sacrifices because Christ’s sin offering is complete. Praise, obedience, generosity, service, and prayer are not payments for guilt. They are the grateful life of people brought near by the great High Priest.

The Biblical Conclusion

What Scripture Establishes About the Role of the High Priest

The high priesthood was God’s appointed lesson in holiness, mediation, representation, and blood atonement. Aaron carried Israel’s names, entered with blood, and ministered under a system that was real but temporary. The repetition of the sacrifices, the weakness of sinful priests, and the boundary of the veil all pointed forward to someone greater. Jesus Christ is that greater High Priest. He is sinless, eternal, and appointed forever. He offered Himself once for all, entered by His own blood, sat down because the work was finished, and lives to intercede for those who come to God through Him. The way is open through Christ, and there is no other mediator.
