The Development of Aquinas’ Idea of Christian Kingship


Aquinas’ idea of Christian kingship is deeply rooted in the concept of Natural Law, building upon previous philosophical and theological principles. This essay will discuss how Aquinas’ concept of Christian kingship incorporates elements such as justice, covenantal statesmanship, and the relationship between religious and civil offices in the medieval context.

I. Natural Law and Justice

Aquinas’ understanding of Christian kingship is grounded in the notion of Natural Law, which holds that there are objective moral principles inherent in the nature of human beings. The concept of justice, as an integral part of Natural Law, plays a crucial role in Aquinas’ idea of Christian kingship.

Aquinas defines justice as giving each person their due, ensuring that everyone receives what they are owed based on their rights and obligations.
Christian kingship, according to Aquinas, involves ruling with justice as the primary virtue, ensuring that the laws and governance of the state reflect the principles of Natural Law.
By upholding justice, Christian kings contribute to the common good, promoting social harmony and stability within society.

II. Covenantal Statesmanship

Aquinas expands on the concept of Christian kingship by introducing the idea of covenantal statesmanship. This notion draws from biblical and theological traditions, highlighting the relationship between the king and God.

Aquinas argues that the authority of a Christian king is derived from God, who establishes a covenant with the ruler.
The king, as God’s representative, has a duty to govern with wisdom and righteousness, guided by God’s divine law.
This covenantal relationship emphasizes the king’s responsibility to uphold the moral and religious values of the community and act as a servant leader.

III. Relationship between Religious and Civil Offices

In medieval times, the relationship between religious and civil offices was closely intertwined. Aquinas addresses this relationship in his concept of Christian kingship, recognizing the distinct roles and responsibilities of both institutions.

Aquinas maintains that the religious office, represented by the Church and its clergy, is responsible for matters of spiritual guidance and salvation.
The civil office, represented by the king and his administration, is responsible for maintaining order, protecting citizens’ rights, and promoting the common good.
While distinct, these two offices are not entirely separate. Aquinas argues that they should cooperate to achieve the ultimate goal of human flourishing and salvation.


Aquinas’ idea of Christian kingship builds upon previous Natural Law concepts by incorporating elements such as justice, covenantal statesmanship, and the relationship between religious and civil offices. By grounding his theory in Natural Law, Aquinas establishes a framework for rulers to govern with justice, guided by divine principles. Furthermore, his concept of covenantal statesmanship emphasizes the king’s duty to serve both God and the community. Lastly, Aquinas recognizes the interplay between religious and civil offices, advocating for their cooperation while maintaining their distinct roles. Through these ideas, Aquinas provides a comprehensive understanding of Christian kingship that was influential during medieval times and continues to shape discussions on governance and leadership today.
