Understanding Hebrews 5:1-4: Called by God

The High Priest in God's Design

To understand why the writer of Hebrews brings up the high priest here, we need to remember that this letter was written to Jewish believers who were familiar with the Old Testament system of worship, where God chose specific people to serve in sacred roles.

God called Aaron to be the first high priest, as it says in Exodus 28:1: 'Then bring near to you Aaron your brother, and his sons with him, from among the people of Israel, to serve me as priests - Aaron and Aaron’s sons, Nadab and Abihu, Eleazar and Ithamar.' On the Day of Atonement, described in Leviticus 16, the high priest entered the Most Holy Place to offer a sacrifice for his own sins and then for the sins of the people, showing that even the spiritual leader needed forgiveness. This entire system was designed by God, not left to human choice, which is why the writer stresses that no one takes this honor on themselves.

These details set the stage for the next point: if even the high priest needed a sacrifice and had to be called by God, how much more does a perfect High Priest - like Jesus - fulfill this role in a way that surpasses the old system?

Christ the High Priest: Called by God and Tender with Our Struggles

The writer of Hebrews reviews Old Testament history to demonstrate how Jesus fulfills the high priest role, which is divinely appointed and compassionate, and is clarified by key Greek terms that reveal His ministry’s purpose.

The word for 'high priest' in Greek is *archiereus*, a title loaded with authority but also limitation in the old system - because every human high priest, like Aaron, had to offer sacrifices for his own sins first, as Hebrews 5:3 makes clear. The writer suggests something greater: Jesus serves as a *mesiteuō*, a mediator, performing more than rituals by bridging the gap between holy God and sinful people, something the old priests could not do. Unlike them, He does not need to atone for His own failures, yet He understands ours because He was tempted in every way, as we are. *Sympatheō* means more than feeling sorry for someone; it means truly sharing their struggle, like a friend who has walked the same hard road.

This changes everything about how we view spiritual leadership. In Jesus’ day, some religious leaders sought honor, building reputations and titles, but Hebrews asserts that true spiritual authority comes only from God’s call - Aaron was called, and Christ was called, as Psalm 110:4 declares: 'You are a priest forever, after the order of Melchizedek.' That verse is not a title; it is a divine appointment that sets Jesus apart from all human priests who came through lineage. He didn’t volunteer - God called Him, confirming it through His resurrection and exaltation.

While the old high priests were weak and repeated sacrifices yearly, Jesus stands as the perfect, once-for-all High Priest - called by God, sinless yet sympathetic, offering Himself for the people’s sins and for ours. His priesthood isn’t based on human effort or status, but on divine calling and shared human experience.

This leads us directly into the next challenge the writer raises: if Jesus is such a compassionate and qualified High Priest, why do so many still struggle to grow in faith? That’s where the next passage takes us - warning against spiritual immaturity and urging us to press on.

Called to Lead, Tempted to Serve: The Heart of True Spiritual Authority

This passage is not about ancient rituals; it is a wake-up call about what real spiritual leadership should look like, then and now.

Back then, the idea that a leader had to be called by God and shaped by weakness was countercultural - many leaders sought status and power, but here we see that true authority comes only through divine appointment, like Aaron’s, and compassion born from shared struggle. The writer of Hebrews presents this standard to honor the past and to point forward to Jesus, who perfectly fulfills it.

Unlike any human priest, Jesus was called by God not through ancestry but by oath, as Psalm 110:4 declares: 'You are a priest forever, after the order of Melchizedek.' He didn’t need to offer for His own sins because He had none, yet He understands our weakness because He was tempted in every way - making Him not only holy but deeply sympathetic. And this changes how we follow Him: we don’t look to leaders who seem flawless or self-promoting, but to Christ, who leads with humility and grace, and calls us to grow beyond spiritual infancy into maturity.

The Priesthood That Changes Everything: From Aaron to Melchizedek and Us

This passage is not a setup for the deep dive into Melchizedek in Hebrews 7; it is a divine bridge from the old system of sacred mediators to a new reality where Christ’s priesthood reshapes how all believers relate to God.

The writer points us to Psalm 110:4 - 'The Lord has sworn and will not change his mind, You are a priest forever, after the order of Melchizedek' - to prove Jesus’ superiority over Aaron and to show that God always planned a different kind of priesthood, one not tied to lineage or temple rituals. Melchizedek, this mysterious figure from Genesis 14:18 who blessed Abraham and had no recorded beginning or end, becomes a living picture of a priest who transcends the old system. Now, in Christ, that eternal priesthood is fulfilled - not temporary, not flawed, but permanent and perfect.

This truth struck at the heart of the Reformation debate over the 'priesthood of all believers,' rooted in 1 Peter 2:9 - 'But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light.' Because Jesus is our once-for-all High Priest, we no longer need human mediators to approach God. Every believer can come directly into His presence, not because we’re worthy, but because Christ has made us priests through His sacrifice. This doesn’t erase leadership in the church, but it redefines it: leaders aren’t a separate class, but fellow sinners called to serve, equip, and point others to Jesus. It means in our church groups, we stop treating pastors like distant authorities and start living as brothers and sisters who all have access to God.

So what changes? We stop chasing religious status and start serving with humility, knowing our authority - if we have any - comes only from God’s call, not our résumé. And as we’ll see next, if we’ve been given such direct access to God through Christ, why are so many still stuck needing milk when they should be eating solid food?
