Covenant Theology — Catholic vs. LDS

Catholic covenant theology begins with a simple observation: the biblical covenants expand. They do not repeat. Each covenant draws a wider circle of people into deeper communion with God, and each covenant introduces genuinely new elements that were not present in what came before.

The pattern is unmistakable. God makes a covenant with one married couple in Eden, establishing the basic structure of human life in relation to Himself. After the Fall and the Flood, He covenants with one household — Noah and his family — preserving the human race and establishing the moral law written on the heart. With Abraham, the scope widens to one tribe, and the content deepens: God promises land, descendants as numerous as the stars, and — crucially — that through Abraham's seed, all the nations of the earth will be blessed. With Moses, the covenant encompasses one nation, Israel, and introduces the Torah, the sacrificial system, and the Levitical priesthood. With David, God establishes one kingdom, promising an everlasting throne and a son whose reign will never end.

And then Christ. In the New Covenant, every previous covenant finds its fulfillment. The scope reaches its maximum — all nations — as Jesus commands His apostles to baptize every people on earth. The intimacy reaches its maximum: God does not merely walk with His people (as with Adam), or promise them land (as with Abraham), or give them laws (as with Moses). He gives them Himself — His Body and Blood in the Eucharist, His Spirit dwelling within them, incorporation into His very life through baptism.

This is what Hahn calls divine pedagogy: God teaching humanity progressively, building understanding layer upon layer, the way a father teaches a child. The child does not learn calculus before arithmetic. God does not reveal the Trinity before He reveals monotheism. He does not give the Eucharist before He gives the Passover lamb. Every stage is real and meaningful in itself, but every stage also points beyond itself to something greater. The beauty of this model is that it takes the entire Bible seriously — Genesis through Revelation is one story going somewhere.

LDS covenant theology operates on fundamentally different assumptions. In the Mormon framework, Adam did not live in a state of developing understanding. He possessed the fullness of the gospel from the beginning — including the Melchizedek priesthood, the plan of salvation, the temple endowment, and baptism by immersion. This fullness was lost through apostasy after Adam's death, then restored to Enoch. Lost again. Restored to Noah. Lost again. Restored to Abraham, then Moses, then the apostles after Christ — and lost again in the "Great Apostasy" until Joseph Smith restored it for the final time in 1830.

The covenants in LDS theology are thus not stages in a progressive revelation but ordinances — specific ritual acts that each individual must receive (either in life or by proxy after death) to progress toward exaltation. Baptism, confirmation, the temple endowment, celestial marriage, and sealing ordinances constitute the "covenant path." The emphasis falls not on God's fatherly plan unfolding through history but on individual compliance with a checklist of sacred procedures.

This produces a very different relationship between God and the covenant-maker. The LDS scripture Doctrine and Covenants 82:10 states: "I, the Lord, am bound when ye do what I say; but when ye do not what I say, ye have no promise." The framework is transactional. God binds Himself in response to human obedience. The Catholic vision, by contrast, is fundamentally gratuitous: God initiates, God sustains, God fulfills. Human cooperation is real but secondary. The covenant is a gift before it is an obligation.

The biblical text simply does not support the claim that Adam possessed the fullness of the gospel. Genesis presents Adam and Eve in a state of original innocence, not as temple-going practitioners of a fully articulated ordinance system. The Abrahamic covenant introduces genuinely new elements — the promise of land, of nationhood, of universal blessing — that make no sense if Abraham already had everything Adam had. The Mosaic covenant adds an elaborate legal and sacrificial system that Paul explicitly describes as a later addition to the Abrahamic promise, not a restoration of something lost:

Paul's logic here is devastating to the LDS model. He treats the Mosaic law as something that came after the Abrahamic covenant — not as a restoration of something Abraham already had and lost. The law is an addition, not a retrieval. If the fullness already existed with Adam and was merely cycled through dispensations, Paul's entire argument in Galatians collapses into incoherence.

The Davidic covenant likewise introduces a genuinely novel concept: an everlasting royal dynasty through which God will rule His people. David does not "restore" a kingship that Adam had. He receives something new — something that simultaneously fulfills God's promise to Abraham and points forward to a greater King yet to come.

The entire argument of the Letter to the Hebrews collapses if the LDS dispensational model is correct. The author of Hebrews argues at great length that the Levitical priesthood was inherently inferior and temporary — a "shadow" pointing forward to Christ's superior priesthood "according to the order of Melchizedek":

If Moses already had the Melchizedek priesthood — as LDS theology explicitly claims — then the author of Hebrews is arguing against a straw man. You cannot call the Levitical system a "shadow" of good things to come if the reality was already fully present in every prior dispensation. The Catholic reading takes Hebrews at face value: the old was genuinely preparatory, and the new genuinely fulfills. The LDS reading requires you to believe that the inspired author of Hebrews either did not know or did not care that Moses already possessed the very thing Hebrews says the Mosaic system lacked.

The single most important covenant prophecy in the Old Testament — the passage that gives the "New Testament" its very name — comes from Jeremiah:

Jeremiah's language is unmistakable. The coming covenant will be new — and explicitly not like what came before. He is not anticipating a restoration of something previously known and lost. He is announcing something genuinely unprecedented. Jesus Himself at the Last Supper identifies His blood as "the blood of the new covenant" (Luke 22:20), directly invoking Jeremiah's prophecy. The Catholic Mass preserves this language in every Eucharistic prayer, locating the faithful inside Jeremiah's fulfillment.

The LDS model has no satisfactory way to explain why God would call something "new" and "not like the former covenant" if it was actually a return to an original, primordial pattern. If Adam already had what Christ was bringing, then the New Covenant is not new at all — it is merely the latest iteration of the oldest thing there is. But that is not what Jeremiah says, and it is not what Jesus says.

One of Hahn's most important contributions to covenant theology is his demonstration that biblical covenants are family-making instruments. A covenant is not a contract between strangers negotiating terms. It is a sacred bond that creates kinship — the way marriage makes two families into one, or the way adoption makes a stranger into a son. God's covenants with Israel are consistently described in familial language: He is a Father, Israel is His son, the covenant community is a household.

In Catholic sacramental theology, this familial logic pervades everything. Baptism is adoption into God's family. The Eucharist is the family meal of the covenant. Confirmation is the anointing of the adopted son or daughter with the Holy Spirit. The sacraments do not merely symbolize a transaction — they effect what they signify. They make the recipient a child of God in reality, not merely in metaphor.

The LDS framework, for all its emphasis on "eternal families," operates on a fundamentally different logic. Covenants are conditions: perform the ordinance, keep the commandments, receive the blessing. D&C 82:10 — "I, the Lord, am bound when ye do what I say" — places the initiative with the human actor. God responds to compliance. This is closer to the contractual framework that Paul critiques in Galatians than to the gratuitous, fatherly initiative that defines the biblical covenants from Abraham onward.

Catholic covenant theology culminates in theosis — the creature drawn into the inner life of the Trinity without ceasing to be a creature. "God became man so that man might become God," as St. Athanasius wrote, but this becoming is participation, not replacement. The creature remains a creature, glorified and transformed by grace, sharing in the divine nature (2 Peter 1:4) while the infinite distinction between Creator and creature is preserved.

The LDS covenant path culminates in exaltation — the individual becoming a god in the fullest ontological sense, possessing the capacity to create spirit children and rule worlds. The Father Himself, in LDS theology, was once a man who progressed to godhood, and the faithful will do the same. This is not participation in God's nature; it is replication of God's career.

These declarations from Isaiah are absolute and unqualified. No god was formed before the Lord; none shall be formed after Him. The Catholic vision of theosis honors these texts completely — the creature is glorified, not deified in the LDS sense. The LDS vision of exaltation requires reading Isaiah's emphatic monotheism as something other than what it plainly says.

The Catholic covenantal framework, as Hahn and others have articulated it, offers a reading of Scripture that respects the text's own internal logic — its genuine development, its forward momentum, its typological structures, its climactic fulfillment in Christ and His Church. The LDS framework imposes an external schema — dispensational loss and restoration — that the biblical text does not support and that creates serious tensions with Hebrews, Jeremiah, Galatians, and Isaiah.

When Paul says the Law came 430 years after Abraham, he means it. When Hebrews calls the Levitical system a shadow, it means it. When Jeremiah announces a covenant that is new and not like what came before, he means it. When Isaiah declares that no god was formed before or after the Lord, he means it. The Catholic reading lets these texts say what they say. The LDS reading requires each of them to mean something other than what it plainly states.

The Bible is not a story of God repeatedly failing to preserve His truth and needing to start over. It is the story of a Father who keeps His promises — who teaches His children one step at a time, who never abandons what He has begun, and who brings every promise to its fulfillment in the person of Jesus Christ and the sacramental life of the Church He founded. That Church has been carrying the New Covenant forward — unbroken, uninterrupted — for two thousand years. The gates of hell have not prevailed against it, and they never will.
