Why replace Moses' covenant for Jesus?
Why should the covenant through Moses be replaced if Hebrews 3:3-6 claims Jesus is greater, without historical or archeological proof of Jesus' authority then?

I. Understanding Hebrews 3:3–6

Hebrews 3:3–6 states:

“(3) For Jesus has been counted worthy of greater glory than Moses, just as the builder of a house has greater honor than the house itself. (4) And every house is built by someone, but God is the builder of everything. (5) Now Moses was faithful as a servant in all God’s house, testifying to what would be spoken later. (6) But Christ is faithful as the Son over God’s house. And we are His house, if we hold firmly to our confidence and the hope of which we boast.”

This passage underscores a core theme of Hebrews: Christ is superior to all Old Testament figures, including Moses. The writer addresses the concern that if Moses was the very conduit of Israel’s foundational covenant (Exodus 19–24), then why should a new covenant supersede what was already central to the Israelite faith? The question becomes especially pointed if there seemed to be no immediate, tangible historical or archaeological proof of Jesus’ authority at that specific time in history.


II. The Mosaic Covenant as Foundational

Moses’ role was unique in Israel’s history. He is described as speaking with God “face to face” (Numbers 12:8) and was entrusted to deliver the Law on Mount Sinai (Exodus 19:3–8). The Mosaic Covenant served to form Israel as God’s chosen people, setting the nation apart with moral, ceremonial, and civil laws.

By defining the Israelites’ religious identity and worship, this covenant was viewed as foundational. Its outward rituals (including sacrifices and festivals) were designed to prefigure deeper truths (Hebrews 10:1). Yet the Old Testament itself points to a far-reaching promise of something more complete—an everlasting covenant (Jeremiah 31:31–34) that would write God’s law on the hearts of His people.


III. Fulfillment and Superseding of the Mosaic Covenant

1. Prophesied New Covenant

Several Old Testament passages, including Jeremiah 31:31–34, forewarned that the Law would not remain a mere external code. Ezekiel 36:26–27 spoke of a transformation through a new heart and Spirit. These prophecies echoed a covenant beyond Moses, in which the people would be intimately indwelt by God. The Book of Hebrews explicitly argues that Jesus inaugurated this better covenant (Hebrews 8:6–13).

2. Jesus as the Mediator

Moses served as the mediator of the Old Covenant (Galatians 3:19). Jesus, by virtue of His divine nature and atoning work, ushered in a new relationship between God and humanity. Hence, where Moses was a faithful servant within God’s house (Hebrews 3:5), Jesus is the Son who stands over God’s house (Hebrews 3:6). This shift does not nullify Moses’ importance but locates his role under a more comprehensive and eternal purpose fulfilled in Christ.

3. Completion and Fulfillment

Jesus Himself stated He came not to abolish the Law, but to fulfill it (Matthew 5:17). “Fulfillment” indicates the completion of all that the Law and the Prophets anticipated. The sacrificial system pointed ahead to the ultimate sacrifice—Christ on the cross (John 1:29; Hebrews 9:26–28). Thus, the new covenant supersedes, not by undermining Moses’ ministry, but by completing what Moses’ covenant established as a type or shadow.


IV. Evidence for Jesus’ Authority in His Historical Context

1. Contemporary Recognition

Although there was no monument in first-century Judea reading “Jesus is greater than Moses,” Jesus’ extraordinary authority was recognized by many contemporaries. The Gospels record that people were amazed because “He taught as one who had authority, and not as their scribes” (Matthew 7:29). Historical references by sources such as the Jewish historian Josephus (Antiquities of the Jews, Book 18) and the Roman historian Tacitus (Annals, Book 15) affirm Jesus’ real-life ministry and crucifixion.

2. Confirmed through Miracles

The Gospels and early Christian testimony recount numerous miracles performed by Jesus—a tangible demonstration of divine authority. Even in the Old Testament, miracles served as validation that a prophet was firmly under God’s hand (e.g., Exodus 4:1–5 for Moses). Jesus’ signs (healing the blind and lame, raising the dead, etc.) paralleled and in many ways surpassed Moses’ miracles. Early Jewish leaders likewise recognized extraordinary works, though they often interpreted them in conflicting ways (John 11:47–48).

3. The Resurrection as Ultimate Proof

The center of Christian claims is the resurrection of Christ (1 Corinthians 15:3–8). This event stands as the decisive vindication of Jesus’ authority and identity. Early eyewitness testimony, recorded in multiple independent sources (the Gospels, Acts, letters of Paul), all converges on the historical claim that the tomb was found empty and that Jesus appeared to many individuals and groups. Archaeological or textual “proof” in the sense of a physical artifact proclaiming His authority may not exist like a Roman legal decree, but the cumulative weight of eyewitness accounts, the transformation of disciples, the birth of the early church, and corroboration from secular historians collectively offer a compelling case.

4. Documentary and Manuscript Evidence

The rapid spread of New Testament documents, the voluminous manuscript evidence (far more than any ancient secular work), and archaeological support for the historical settings in the Gospels reinforce the reliability of the records describing Jesus. Significant papyri and codices, such as the Chester Beatty Papyri, Codex Sinaiticus, and Codex Vaticanus, date closer to the original writings than most ancient texts. These manuscripts uphold the authenticity of the claims made about Christ long before religious or political institutions could have invented them.


V. The Necessity of Faith and Covenant Relationship

1. The Role of Trust

While historical corroboration bolsters Christian claims, biblical faith ultimately rests on trust in God and His revealed truth. Hebrews 11:1 defines faith as “the assurance of what we hope for and the certainty of what we do not see.” Moses himself required faith to lead the people out of Egypt, trusting in God’s promises. Jesus invited people to believe not merely because of visible signs but because of who He is in fulfillment of Scripture (John 10:37–38).

2. Transformation from Within

The new covenant is written on hearts (Jeremiah 31:33). Moses gave stone tablets; Jesus writes upon believers’ hearts through the Holy Spirit (2 Corinthians 3:3). This inward transformation indicates God’s intention: not simply external conformity but a new nature in Christ. The experiential reality of Christians living differently (testifying to changed lives throughout history) demonstrates the power of this covenant that surpasses the old.

3. From Shadows to Reality

Many ancient Israelites looked forward to a coming Messiah who would transcend the limitations of the Law (Romans 8:3–4). The Law revealed sin (Romans 3:20) but could not ultimately redeem humanity—only the perfect sacrifice of Christ could. Thus, the Mosaic Covenant was never an end in itself; it was a critical step in the unfolding plan that culminates in Christ.


VI. Conclusion

Moses stands as a towering figure in salvation history, entrusted with the foundational covenant that shaped Israel’s identity. Yet from its very inception, that covenant prepared the people for something greater—a covenant not written merely on stone but etched into human hearts. Hebrews 3:3–6 affirms Jesus’ authority over God’s house, surpassing Moses, because as the eternal Son and resurrected Lord, He delivers what Moses’ covenant could only prefigure.

Despite lacking a single monumental proof that declares His superiority in an archaeological sense, the collective testimony of Scripture, corroborating historians, early manuscripts, remarkable miracles, and most decisively the resurrection, testifies to Jesus’ unique and ultimate authority. All of this, in keeping with God’s promise through the prophets, forms the solid ground upon which the new covenant stands.

Thus, the Israelites’ foundational covenant through Moses is not discarded but fulfilled and superseded in Christ. What was once anticipated in the Law finds its completion in Him—revealing that the greater glory belongs to the One who not only built the house but also reigns over it as the Son.
