One Story of Salvation: The Covenants in Catholic Thought
This report explores the Catholic theological perspective on the relationship between the Old and New Testaments. The core principle is not that the New Covenant abolishes the Old, but rather that it brings it to its ultimate meaning and perfection in Jesus Christ. The Old Testament is indispensable, and its covenant has never been revoked. Christians believe God had one ongoing plan for salvation, revealed first to the Israelites and then to all peoples through Jesus Christ. The New Testament and Old Testament, therefore, tell one continuous story of salvation.
What is a Covenant?
In a theological sense, a covenant is a solemn, binding agreement that establishes a sacred family bond between God and humanity. It is much more than a contract; it creates a relationship of kinship and shared life.
The Progression of Covenants in Catholic Thought
Catholic theology understands God's relationship with humanity as a series of progressive covenants, or sacred bonds, that unfold over time. Each covenant builds upon the last, culminating in the final and definitive covenant established by Jesus Christ.
Old Covenants
These were the covenants made with figures like Noah, Abraham, and Moses. They were promises and laws that progressively prepared God's people for the Messiah. These covenants were real, but also preparatory and ultimately imperfect.
Christ as the Fulfillment
Jesus Christ is the ultimate fulfillment of all the Old Covenants. He is the New Adam, the ultimate priest, and the true King of the line of David. In Him, all of God's previous promises and plans find their intended meaning and perfection.
New & Eternal Covenant
Jesus establishes the New and Eternal Covenant through His death and resurrection. This covenant is not merely a legal agreement but a spiritual bond of grace, open to all humanity and intended to last forever, making the old covenants no longer necessary.
The Great Fulfillment
The Catholic Church teaches that Jesus Christ fulfills the central institutions of the Old Covenantβthe Law, the Temple, and the Sacrificial system. He does not destroy them, but elevates them to their definitive, spiritual reality. Below is an exploration of how each element is transformed and perfected in the New Covenant.
The Law
Old Covenant: The Mosaic Law
God gave the Law to Moses on stone tablets. It was an external code of commandments, customs, and rituals that governed the life of the people of Israel.

Sacrifice of Christ (Eucharist)
He offers Himself, making further sacrifices obsolete. The Eucharist perpetuates this one sacrifice.
 
If the New Covenant fulfills the Old, why do we still read the Old Testament?
The Old Testament is not a discarded relic, but an indispensable and permanently valuable part of the Christian faith. It is essential for understanding the full story of salvation.
Historical Context
It provides the essential historical and cultural foundation for the New Testament, offering valuable insight into the Jewish customs and prophecies that enriched Jesus' life and teachings.
Moral Guidance
It is a treasure trove of moral and spiritual wisdom, with the Ten Commandments and Wisdom literature serving as foundational ethical codes that have shaped Christian moral teaching.
Typology
It contains significant typological value, where events and people (like the Passover lamb) prefigure what is fully realized in the New Testament through Christ, revealing the coherence of God's plan.
Liturgical Worship
The Old Testament plays a central role in Catholic liturgy and prayer, with readings at Mass and the Psalms forming the core of the Church's prayer life, making it a living part of the faith.
The New Testament Hidden in the Old
This foundational principle, articulated by St. Augustine, holds that the Old Testament contains veiled truths and foreshadows that are fully revealed only in the New Testament. In turn, the New Testament's full meaning is illuminated by a proper understanding of the Old. It's a single, coherent story of salvation.
The New is Hidden in the Old
This means the Old Testament is not a dead letter, but a living prophetic book. Its stories, figures, and rituals are seen as types or foreshadows of what is to come. For example, the Passover lamb and the manna in the desert prefigure the sacrifice of Christ and the Eucharist. Without the Old Testament, the New Testament lacks context and depth.
The Old is Manifest in the New
This means the New Testament is the definitive key that unlocks the full meaning of the Old. What was previously a mystery is now made clear. Jesus and the apostles, under the inspiration of the Holy Spirit, reveal the ultimate purpose of the Law, the Temple, and the priesthood. The New Testament is not a new story, but the climactic chapter that brings the Old to its perfect fulfillment.
The New Ark of the Covenant
Typology, where an Old Testament reality prefigures a New Testament one, is key to understanding salvation history. The most sacred object of the Old Covenant, the Ark, is seen as a perfect type for the Blessed Virgin Mary, who carried the reality of God's presence within her.
The Ark of the Old Covenant
A vessel of pure gold, housing the signs of God's covenant with Israel.
- 
                                    π

The True Bread of Life
Carried Jesus, the true Bread from Heaven given for the life of the world.

                                    π
                                    
The Eternal High Priest
Carried Jesus, the ultimate and eternal High Priest who offers Himself.
 
The New Israel
The "New Israel" is the Church, a universal people of God where "there is neither Jew nor Gentile." This does not nullify God's covenant with the Jewish people, but expands it to all humanity. This Catholic understanding differs significantly from some Protestant views, particularly regarding the modern state of Israel.

"The Church, the People of God of the New Covenant, is a spiritual community that 'draws sustenance from the root of that well-cultivated olive tree onto which the wild shoots, the Gentiles, have been grafted.' God's gifts and calling to the Jewish people are irrevocable, and they are not to be presented as rejected or accursed."
