1. Introduction
Following the early Church Fathers, Christian theologians in the medieval and Reformation periods continued to reflect on the structure of salvation history and the unfolding of God’s purposes in the world. Although these thinkers did not formulate dispensational theology in its modern form, their work significantly influenced later discussions concerning the relationship between law, grace, covenant, and divine administration.
Medieval theologians emphasised the unity of God’s redemptive plan, while Reformation theologians sought to clarify the relationship between the Old and New Testaments. These developments laid important foundations for later theological systems, including both covenant theology and dispensational theology.
2. Medieval Interpretations of Salvation History
During the medieval period, theologians often interpreted biblical history through a unified theological framework emphasising the continuity of God’s covenantal dealings with humanity. The dominant approach emphasised the idea that the entire biblical narrative reveals a single divine plan unfolding across time.
One of the most influential medieval theologians was Thomas Aquinas. In his theological synthesis, Aquinas emphasised the unity of divine revelation while acknowledging differences between the Old and New Covenants.
According to Aquinas, the Old Law given through Moses served as a preparation for the fuller revelation of grace through Christ. In this sense, the Mosaic covenant functioned as a pedagogical stage within the broader divine plan, guiding humanity toward the ultimate revelation of salvation in Christ (Aquinas, 1947).
Medieval theology therefore recognised distinctions between stages of revelation while maintaining the fundamental unity of God’s redemptive purpose.
3. The Role of Law and Grace
A key theme in medieval theology was the relationship between law and grace. The Mosaic law was often interpreted as a divinely instituted system designed to instruct and discipline God’s people before the coming of Christ.
The New Testament itself reflects this understanding. The Apostle Paul writes:
“So the law was our guardian until Christ came that we might be justified by faith” (Galatians 3:24).
Medieval theologians interpreted this relationship as evidence that God’s plan unfolds progressively, with earlier stages preparing for later fulfilment.
However, these distinctions were not interpreted as separate dispensations in the modern sense. Instead, they were understood as different expressions of the same overarching covenantal relationship between God and humanity.
4. Reformation Theology and the Structure of Biblical History
The Protestant Reformation of the sixteenth century introduced new debates regarding the interpretation of Scripture and the relationship between the Old and New Testaments. Reformers emphasised the authority of Scripture and sought to interpret biblical history in ways that highlighted the centrality of Christ.
Among the most influential reformers was John Calvin. Calvin argued that the Old and New Testaments share a fundamental unity because both reveal the same covenant of grace.
In his Institutes of the Christian Religion, Calvin wrote that the difference between the covenants lies primarily in their form of administration, not in their essential substance (Calvin, 1960).
Thus, while the Old Testament contains types and shadows that anticipate Christ, the underlying promise of salvation remains the same throughout both Testaments.
5. The Emergence of Covenant Theology
During the Reformation and post-Reformation period, many Protestant theologians developed what later became known as covenant theology. This framework interprets biblical history primarily through the lens of covenants rather than dispensations.
Covenant theologians generally describe the biblical narrative through several major covenants, including:
- the covenant with Adam
- the covenant with Abraham
- the Mosaic covenant
- the new covenant established through Christ
These covenants are often understood within the broader theological concepts of the covenant of works and the covenant of grace.
This covenantal framework emphasises the continuity of God’s redemptive purpose across history and tends to minimise sharp divisions between different historical periods.
6. Continuity and Fulfilment
One of the central themes of Reformation theology was the belief that the Old Testament finds its fulfilment in Christ. The New Testament frequently interprets Old Testament promises as pointing toward Christ and the salvation He brings.
For example, Jesus declares:
“Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfil them” (Matthew 5:17).
This emphasis on fulfilment reinforces the idea that the different stages of biblical history should be understood as parts of a unified divine plan rather than as entirely separate systems.
7. Influence on Later Dispensational Thought
Although medieval and Reformation theologians generally emphasised continuity rather than separation between historical stages, their discussions nevertheless contributed to later dispensational thinking.
Several themes that later dispensational theologians would emphasise were already present in earlier theology:
- recognition of different historical stages in God’s plan
- the distinction between law and grace
- the progressive unfolding of divine revelation
However, the key difference lies in the degree of separation between these stages. Whereas covenant theology emphasises continuity, dispensational theology later developed a stronger emphasis on distinct administrative periods within salvation history.
8. Conclusion
Medieval and Reformation theologians played a crucial role in shaping the Christian understanding of salvation history. While they did not construct a dispensational system, they carefully examined the relationship between law, grace, covenant, and the unfolding revelation of God’s purposes.
The theological frameworks developed during this period—particularly covenant theology—provided the intellectual context from which later dispensational interpretations would emerge. These earlier traditions emphasised the unity of God’s redemptive plan while acknowledging the progressive nature of divine revelation.
The next article in this series will examine the rise of modern dispensationalism in the nineteenth century, when theologians began to formulate a more systematic division of biblical history into distinct dispensations.
