The Priesthood: Guardians of Holiness and Mediators of God’s Law

The role of the priesthood in the Old Testament was foundational to the spiritual life of Israel. Priests were not merely religious functionaries; they were appointed by God as mediators, teachers, and caretakers of the sacred Law. In Leviticus 8 and Numbers 18:1-7, we see the consecration of Aaron and his sons, and the responsibilities given to the priestly line. Their duties were essential for administering the Law, maintaining the holiness of the community, and facilitating the worship of God. Let’s explore the significance of the priesthood and how it reveals God’s desire for a holy people who live in accordance with His commands.

Consecrated for Service: The Ordination of the Priesthood

The establishment of the priesthood began with a solemn and sacred ceremony detailed in Leviticus 8. Aaron and his sons were set apart for their unique role through a process of consecration, involving sacrifices, anointing, and the donning of special garments. In Leviticus 8:6-9, it is written: “Then Moses brought Aaron and his sons and washed them with water. And he put the tunic on him, girded him with the sash, clothed him with the robe, and put the ephod on him; and he girded him with the intricately woven band of the ephod, and tied the ephod on him. Then he put the breastplate on him, and he put the Urim and the Thummim in the breastplate.”

This consecration ritual symbolized purification and the setting apart of the priests for holy service. The washing with water represented the need for spiritual cleansing, while the garments signified the priests’ special role in the community. The anointing oil, poured on Aaron’s head, was a sign of the Holy Spirit’s presence, empowering the priests for their divine duties. In Leviticus 8:12, Moses anoints Aaron: “And he poured some of the anointing oil on Aaron’s head and anointed him, to consecrate him.”

The ordination of the priests underscores the seriousness of their role. They were chosen by God to be holy mediators between Him and the people. Their consecration reminds us that those who serve in God’s presence must be set apart, embodying the holiness that God requires of His people.

Mediators Between God and Man: Offering Sacrifices and Making Atonement

One of the primary duties of the priests was to offer sacrifices on behalf of the people. The sacrificial system was a central component of the Law, providing a way for the Israelites to atone for their sins and maintain fellowship with God. In Numbers 18:1, God speaks to Aaron about the priestly responsibility: “Then the Lord said to Aaron: ‘You and your sons and your father’s house with you shall bear the iniquity related to the sanctuary, and you and your sons with you shall bear the iniquity associated with your priesthood.’” The priests were tasked with bearing the burden of the people’s sins and interceding for them through sacrifices.

The priests offered a variety of sacrifices, including burnt offerings, sin offerings, and peace offerings, each with its own specific purpose and symbolism. In Leviticus 9:7, Moses instructs Aaron: “Go to the altar, offer your sin offering and your burnt offering, and make atonement for yourself and for the people.” This act of making atonement was a vital function of the priesthood, as it temporarily covered the sins of the people and allowed them to remain in God’s covenant community.

The priests’ role as mediators prefigures the ultimate mediation of Jesus Christ, who offered Himself as the perfect and final sacrifice for sin. In Hebrews 9:12, it is written: “Not with the blood of goats and calves, but with His own blood He entered the Most Holy Place once for all, having obtained eternal redemption.” The priestly sacrifices in the Old Testament were a shadow of the perfect atonement provided by Christ, who fulfills the Law’s requirements and offers lasting reconciliation between God and humanity.

Guardians of Holiness: Teaching and Upholding the Law

In addition to offering sacrifices, the priests were responsible for teaching the people the Law and ensuring that it was upheld in the community. They acted as spiritual leaders and judges, guiding the Israelites in matters of worship and daily life. In Leviticus 10:10-11, God commands Aaron and his sons: “That you may distinguish between holy and unholy, and between unclean and clean, and that you may teach the children of Israel all the statutes which the Lord has spoken to them by the hand of Moses.” The priests were tasked with teaching God’s commandments, helping the people to understand the difference between right and wrong, holy and profane.

The role of the priests as teachers of the Law was crucial for maintaining the covenant relationship between God and His people. By instructing the Israelites in God’s ways, the priests helped to preserve the spiritual health of the nation. Their responsibility was not only to perform rituals but also to guide the people in living lives that reflected God’s holiness.

This teaching role is emphasized in Malachi 2:7, where it is written: “For the lips of a priest should keep knowledge, and people should seek the law from his mouth; for he is the messenger of the Lord of hosts.” The priests were seen as God’s messengers, conveying His truth and helping the people to walk in obedience. This teaching ministry pointed forward to the ministry of Jesus, who taught with authority and brought the fullness of God’s truth.

Bearers of the People’s Burden: Intercession and Prayer

The priests also played a vital role as intercessors, standing in the gap between God and the people. They were called to pray on behalf of the nation, seeking God’s favor and forgiveness. In Numbers 18:7, God explains the priestly duties: “Therefore you and your sons with you shall attend to your priesthood for everything at the altar and behind the veil; and you shall serve. I give your priesthood to you as a gift for service.” The priesthood was a gift, given to serve the people through prayer, sacrifice, and intercession.

One of the most significant acts of priestly intercession took place on the Day of Atonement, when the high priest entered the Holy of Holies to offer a sacrifice for the sins of the entire nation. The high priest would sprinkle the blood of the sacrifice on the mercy seat, symbolizing the covering of the people’s sins. This act of intercession was a powerful reminder of the need for mediation between a holy God and a sinful people.

Jesus, our great High Priest, fulfills this role of intercession perfectly. In Hebrews 7:25, we read: “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.” Jesus’ continual intercession on our behalf guarantees our access to God’s grace and mercy, making Him the ultimate fulfillment of the priestly office.

The Priesthood and the Fulfillment in Christ: A New Covenant of Access

The Old Testament priesthood served as a temporary institution, pointing forward to the perfect High Priest, Jesus Christ. Through His sacrifice, Jesus fulfills the requirements of the Law and establishes a new covenant, granting all believers direct access to God. In 1 Peter 2:9, Peter declares: “But you are a chosen generation, a royal priesthood, a holy nation, His own special people, that you may proclaim the praises of Him who called you out of darkness into His marvelous light.” In Christ, all believers are made part of a royal priesthood, called to serve God and minister His grace to the world.

This transformation signifies the fulfillment of the priesthood’s role in Jesus and the extension of its privileges to all who belong to Him. We no longer need human priests to mediate between us and God because Jesus has opened the way for us to approach the throne of grace with confidence.

Conclusion: Embracing the Priesthood of All Believers

The Old Testament priesthood was essential for administering the Law and guiding God’s people in worship and obedience. The priests served as mediators, teachers, and intercessors, pointing forward to the ultimate fulfillment of these roles in Jesus Christ. Through His life, death, and resurrection, Jesus becomes our perfect High Priest, granting us direct access to God and inviting us to live as a royal priesthood.

As believers, we are called to embrace this priestly role, living lives of holiness, interceding for others, and proclaiming the truth of God’s Word. May we follow in the footsteps of our great High Priest, serving faithfully and reflecting the love and grace of God in all that we do.
