Theology plays a particularly important role in the search for a synthesis of knowledge as well as in the dialogue between faith and reason. It serves all other disciplines in their search for meaning, not only by helping them to investigate how their discoveries will affect individuals and society but also by bringing a perspective and an orientation not contained within their own methodologies. . . . Every Catholic university should have a faculty, or at least a chair, of theology. Catholic theology, taught in a manner faithful to Scripture, Tradition, and the Church’s Magisterium, provides an awareness of the Gospel principles which will enrich the meaning of human life and give it a new dignity.


– Pope Saint John Paul II, Ex Corde Ecclesiae, 19–20


This department seeks to restore and advance the scholastic discipline of Theology, the Queen of the Sciences”. The Instruction on the Ecclesial Vocation of the Theologian reminds us that the object of theology is the Truth which is the living God and His plan for our salvation revealed in Jesus Christ”. (8). Every course is designed both to cover the perennial truth taught by the Church and developed by the Catholic theological tradition, and to expose the false steps which have led to widespread loss of orthodoxy in recent years. As the late Pope John Paul II stressed in his address to the Pontifical Academy of Theology, the vitality of theological study does not lie in a relativism or historicism”. Rather, the theological vocation requires

a supreme concentration on the truth, an understanding that is a journey with and, above all, a following of Christ, the Way, the Truth, and the Life. Theology thus becomes a journey in communion with the Person-Truth who is Jesus Christ, in a relationship of fidelity, love and self-giving, under the guidance of the Spirit of truth (cf. Jn 16,13), who has the mission of recalling Jesus’ words and of helping Christians understand and live them in an interior lucidity throughout the changing history of humanity.” (Address to the Pontifical Academy of Theology, February 16, 2002)

From the Aeterni Patris of Leo XIII, through the Doctoris Angelici of Pius X and the Studiorum Ducem of Pius XI, down to the Second Vatican Council, the Church has taught that the spirit, methods, and principles of the Angelic Doctor, St. Thomas Aquinas, yield the optimal results in speculative theology. Therefore THEO 301, 305, and all the upper division courses in speculative theology include the reading of St. Thomas and are all taught according to his approach. Thus the Theology Department at Christendom College takes special care to insure that the students achieve a solid grasp of the Thomistic synthesis. As was stated in Fides et Ratio,

If it has been necessary from time to time to intervene on this question, to reiterate the value of the Angelic Doctor’s insights and insist on the study of his thought, this has been because the Magisterium’s directives have not always been followed with the readiness one would wish. In the years after the Second Vatican Council, many Catholic faculties were in some ways impoverished by a diminished sense of the importance of the study . . . of Scholastic philosophy. . . . I cannot fail to note with surprise and displeasure that this lack of interest in the study of philosophy is shared by not a few theologians. . . .

It should be clear in the light of these reflections why the Magisterium has repeatedly acclaimed the merits of Saint Thomas’ thought and made him the guide and model for theological studies. . . . In his thinking, the demands of reason and the power of faith found the most elevated synthesis ever attained by human thought, for he could defend the radical newness introduced by Revelation without ever demeaning the venture proper to reason.
Pope Saint John Paul II, Fides et Ratio, Paragraphs 61, 78

As a strict academic discipline, the theology major is an ideal preparation for careers in teaching, in Catholic broadcasting or in religious journalism, for seminary study, and for other graduate work in academic theology. It can lead to positions as directors of religious education in schools, parishes, and dioceses’ growing field.

Requirements for the Theology Major

Theology majors must be able to read ecclesiastical Latin. Proficiency in Latin can be acquired through fulfillment of the College’s language requirement (LATN 202 or higher). The major consists of at least thirty hours, which must include the following THEO courses:

  • 301 Moral Theology and 302 New Evangelization and Apologetics, required of all Christendom students
  • 308 De Deo Trino and 312 De Verbo Incarnato, the two courses that focus specifically on the central mysteries of the Faith, the Trinitarian God, and the mystery of the Word made flesh, Jesus Christ.

  • Five THEO electives numbered 300 or higher
  • THEO 512 Senior Thesis

The minor requires 18 hours of theology from THEO courses numbered 300 or higher. THEO 301 and 302 may be counted toward the THEO minor. A course grade of at least C-minus is necessary for a course to fulfill the department’s major or minor requirements.

Students who complete a major in the THEO department will be able to
