Introduction

The concept of living under Christ's priesthood is central to understanding the New Testament's portrayal of Jesus as the ultimate High Priest. This role is pivotal in the believer's relationship with God, as it signifies a new covenant and a transformative way of approaching the divine. The priesthood of Christ is primarily expounded in the Book of Hebrews, which presents Jesus as the fulfillment of the Old Testament priesthood, offering a perfect and eternal sacrifice for sin.

Christ as High Priest

The Book of Hebrews articulates the superiority of Christ's priesthood over the Levitical priesthood. Hebrews 4:14-16 states, "Therefore, since we have a great high priest who has passed through the heavens, Jesus the Son of God, let us hold firmly to what we profess. For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who was tempted in every way that we are, yet was without sin. Let us then approach the throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need."

This passage highlights several key aspects of Christ's priesthood: His divine nature, His empathetic understanding of human frailty, and His sinlessness. These attributes enable believers to approach God with confidence, knowing that Christ intercedes on their behalf.

The Order of Melchizedek

Christ's priesthood is described as being in the order of Melchizedek, a mysterious figure who appears in Genesis 14:18-20 and is further discussed in Hebrews 7. Unlike the Levitical priests, whose lineage was based on ancestry, Melchizedek's priesthood is characterized by its eternal nature. Hebrews 7:17 affirms, "For it is testified: 'You are a priest forever in the order of Melchizedek.'"

This eternal priesthood signifies that Christ's intercession and sacrificial work are not limited by time or human constraints. His priesthood is perpetual, offering believers a constant source of grace and mediation.

The New Covenant

Living under Christ's priesthood also involves participating in the new covenant, which is superior to the old covenant established through the Law of Moses. Hebrews 8:6 explains, "But now Jesus has received a more excellent ministry, just as the covenant He mediates is better and is founded on better promises."

The new covenant, sealed by Christ's blood, offers believers direct access to God, forgiveness of sins, and the indwelling of the Holy Spirit. This covenant is not based on adherence to the law but on faith in Christ's redemptive work.

The Role of Sacrifice

Central to Christ's priesthood is His once-for-all sacrifice. Unlike the repeated sacrifices of the Levitical priests, Christ's sacrifice was singular and sufficient. Hebrews 9:12 states, "He did not enter by the blood of goats and calves, but He entered the Most Holy Place once for all by His own blood, thus securing eternal redemption."

This perfect sacrifice not only atones for sin but also sanctifies believers, setting them apart for God's purposes. It underscores the completeness and finality of Christ's work on the cross.

Intercession and Advocacy

As High Priest, Christ continually intercedes for believers. Hebrews 7:25 assures, "Therefore He is able to save completely those who draw near to God through Him, since He always lives to intercede for them." This ongoing intercession means that believers have an advocate before the Father, ensuring that their relationship with God is maintained and strengthened.

Implications for Believers

Living under Christ's priesthood has profound implications for believers. It calls for a life of faith, reliance on Christ's finished work, and a commitment to holiness. Believers are encouraged to draw near to God, confident in the access granted through Christ's priesthood. This relationship is marked by grace, mercy, and the transformative power of the Holy Spirit, enabling believers to live in a manner that reflects their identity in Christ.
