-Roman Catholic apologists frequently appeal to a typological connection between Isaiah 22:20–22 and Matthew 16:19 to support the doctrine of papal authority. Both passages reference the symbolic use of “keys” and describe figures—Eliakim in the Old Testament and Peter in the New Testament—who are entrusted with significant authority. The parallels in language, such as “opening and shutting” or “binding and loosing,” are cited to argue that Eliakim serves as a prototype of Peter, whom Christ appoints as the visible head of His church. This article critically examines that typological argument, demonstrating that the comparison is strained, contextually inconsistent, and ultimately incompatible with the theological claims it is meant to support.
- The Symbolism Of Keys Is Thematically Diverse And Contextually Fluid:
-The Bible employs the imagery of “keys” in multiple, unrelated contexts (e.g., Judges 3:25; Luke 11:52; Revelation 1:18), each conveying different kinds of authority or access. The mere presence of “keys” in both Isaiah 22 and Matthew 16 does not necessitate a typological link. In Isaiah, the key signifies administrative control over the royal household of Judah. In Matthew, the keys are given to Peter in a spiritual context, symbolizing ecclesial authority. The polyvalent nature of biblical symbolism cautions against drawing rigid theological conclusions from superficial lexical parallels.
- The Historical And Narrative Contexts Are Fundamentally Dissimilar:
-Isaiah 22 describes a specific historical event: the removal of Shebna due to his corruption and the appointment of Eliakim as steward under King Hezekiah. This was a dynastic, political office within the Davidic monarchy. In contrast, Peter’s commissioning in Matthew 16 occurs in a messianic and eschatological context, with no mention of succession or replacement. Jesus does not depose a prior “steward” nor does He install Peter as a subordinate to an earthly king. The disjunction in context and function undermines the legitimacy of a direct typological correspondence.
- The Predicted Fall Of Eliakim Seems Inconsistent With The Catholic View Of The Papacy:
-Isaiah 22:25 foretells the eventual downfall of Eliakim: “the peg that was fastened in a secure place will give way.” If Eliakim is a type of Peter, then the typology implies that Peter—or his office—would likewise fall, which directly contradicts Catholic claims of the papacy’s indefectibility and infallibility. A typology that undermines the very doctrine it is meant to support is self-defeating.
- The Name “Eliakim” More Accurately Prefigures Christ, Not Peter
-The name “Eliakim,” meaning “God will raise up,” aligns more naturally with Jesus Christ, who is repeatedly described in the New Testament as the one raised up by God (Acts 2:24; Romans 6:4). Furthermore, Revelation 3:7 explicitly attributes the “key of David” to Christ Himself, not Peter. This suggests that the ultimate fulfillment of Isaiah 22 is found in Jesus, the true heir to David’s throne, rather than in Peter or the papacy.
- The Nature Of Their Authority Is Categorically Distinct:
-Eliakim’s role was administrative and bureaucratic, managing the affairs of the royal household. His authority was derivative and temporal, exercised under the reign of a human king. Peter’s role, by contrast, was apostolic and spiritual, rooted in the proclamation of the gospel and the formation of the church. The qualitative difference between their offices—one political, the other ecclesial—renders the typological link tenuous at best.
- The “Falling Peg” Imagery Undermines The Notion Of Perpetual Authority:
-Isaiah 22:23–25 uses the metaphor of a “peg driven into a firm place” to describe Eliakim’s initial stability, but the passage ends with the peg being removed and everything attached to it collapsing. If this imagery is meant to foreshadow Peter and the papacy, it implies that the authority granted is ultimately unstable and impermanent. This directly contradicts Catholic doctrines of papal infallibility and apostolic succession, which assert the enduring and unbroken nature of the papal office. The typology, if pressed, leads to theological incoherence within the Catholic framework.
- Biblical Symbolism Must Be Interpreted Within Its Literary And Theological Context:
-While both Isaiah 22 and Matthew 16 use the imagery of keys, the meaning of that imagery is shaped by its narrative and theological setting. In Isaiah, the key represents control over access to the king and his resources, a gatekeeping function within a royal court. In Matthew, the keys represent spiritual authority to bind and loose, a rabbinic idiom for teaching and disciplinary authority within the community of believers. The shift from political to spiritual, from national Israel to the universal church, signals a transformation in the meaning of the symbol. This evolution cautions against reading the two passages as directly predictive or typologically bound.
- The Typology Lacks New Testament Affirmation:
-Unlike other typologies that are explicitly affirmed by New Testament writers, such as Adam as a type of Christ (Romans 5:14) or Melchizedek as a type of Christ’s priesthood (Hebrews 7), the Eliakim-Peter connection is never mentioned or endorsed by Jesus or the apostles. If this typology were foundational to ecclesiology, one would expect it to be clearly taught or referenced in the New Testament. Its absence suggests that the connection is speculative rather than divinely instituted.
- The Shift From Singular To Plural Keys Indicates A Broader Scope:
-Isaiah 22 refers to “the key of the house of David” in the singular, denoting a specific administrative authority. Matthew 16, however, speaks of “the keys of the kingdom of heaven” in the plural, which may reflect a broader, more expansive spiritual mission. This numerical shift in the symbolism suggests that any authority given to Peter is not a direct continuation of Eliakim’s role, but a transformation of the concept to fit a new covenantal context.
- Overextension Of Typology Risks Doctrinal Instability
-Typology is a valuable interpretive tool when used within the bounds of Scripture’s own affirmations. However, when typology is stretched beyond its textual support, it can lead to doctrinal conclusions that are speculative or even contradictory. The Eliakim-Peter typology involves multiple layers of inference, none of which are explicitly taught in Scripture, and risks building theological claims on unstable ground. Sound doctrine must rest on clear biblical teaching, not on tenuous symbolic parallels.
- The Absence Of the Holy Spirit In Isaiah 22 Highlights A Key Discontinuity:
-Peter’s leadership in the New Testament is inseparable from the work of the Holy Spirit, particularly at Pentecost (Acts 2), where apostolic authority is confirmed and empowered. Isaiah 22, however, contains no reference to divine empowerment or spiritual commissioning. Eliakim’s authority is purely administrative, not prophetic or spiritual. This absence further underscores the dissimilarity between the two roles and weakens the argument that Eliakim foreshadows Peter’s ecclesial leadership.
-The attempt to draw a typological line from Eliakim in Isaiah 22 to Peter in Matthew 16 relies on superficial similarities while ignoring crucial contextual, theological, and narrative differences. The divergent nature of their offices, the instability of Eliakim’s tenure, and the broader biblical usage of “keys” all point to the conclusion that Isaiah 22 does not prefigure the papacy. Rather than reinforcing Catholic claims, the typology, when examined closely, raises more problems than it resolves. A sound hermeneutic requires that we respect the integrity of each passage within its own covenantal and historical framework, rather than forcing them into a theological mold that they were never intended to fit.
