Schools Of Thought In Catholic Theology

Due to the complexity of its object (God), Catholic theology has given rise to several philosophical and theological traditions, or schools of thought. 

While these theological traditions emphasize different concepts, they should in no way be considered denominations within the Catholic Church. Rather, each school of thought is a unique tessera that makes up the larger mosaic of Catholic theology. These schools can be categorized by their traditions. For example, one can speak of philosophical, theological, and spiritual traditions that compose the focus of these schools.

In this essay, I will endeavor to examine and explain the most significant of the philosophical and theological schools. What follows does not in any way exhaust the thought of these schools. Rather, this essay seeks to provide a brief exposition of the teachings of these traditions.

Thomism

Based on the teachings of Saint Thomas Aquinas, Thomism is likely the most influential and consistent of the Catholic schools. Thomas Aquinas created a philosophical system that integrated Catholic doctrine with elements from Aristotle’s philosophy.

As such, he augmented the Neo-Platonic view of philosophy that, after Augustine, became tremendously influential amongst medieval philosophers. Aquinas is therefore widely regarded as having shifted the focus of Scholastic philosophy from Plato to Aristotle. 

Thomism emphasizes harmonizing faith and reason. In this sense, it is holistic in its approach. Since both faith and reason originate in God, reason can (in a limited way) understand God, while faith reveals mysteries beyond its grasp (such as the Holy Trinity). 

Since Thomism holds that human knowledge begins with sensory experience and observation (contrary to extreme rationalism), it is reason that allows one to comprehend reality and God. However, because the intellect is finite and fallible, this comprehension of the transcendent God is limited.

Aquinas, therefore, stresses that while God can be known through natural revelation and logic, this knowledge is analogical (e.g., God’s goodness is like human goodness, but infinitely greater). 

In adopting Aristotelian philosophy, Thomistic cosmology holds that the universe operates according to cause and effect, pointing to an uncaused first cause, God, who initiated motion and existence. Aquinas’s arguments do not just point to God; they are philosophical proofs.

Moreover, God is the ground or source of objective morality. Human beings participate in God’s eternal law through reason. It is for this reason that we are able to discern moral principles.

Thomism does not hold that moral principles or ethics exist in a vacuum, but rather that they illuminate the inherent purposes and goals (telos) in human beings. While these goals include so-called worldly goods such as self-preservation, procreation, knowledge, and society, the summum bonum or highest good for man is the beatific vision. This eternal beatitude with God is only possible because God’s grace elevates and perfects human nature.

Lastly, Thomistic anthropology draws on Aristotelian principles by holding to hylomorphism. Hylomorphism is the view that human beings are composed of an intellectual and spiritual soul, the principle of life, and organic matter, the body.

Augustinianism

Augustinianism is a deeply influential school based on the teachings of Saint Augustine. Indeed, with the possible exception of Thomas Aquinas, no theology has had a greater effect on the Catholic Church than the one developed by Augustine of Hippo.

Augustine’s theology emphasizes the necessity of divine illumination, the primacy of grace, and a Platonic worldview.

Augustinianism holds a rather dim view of the human condition after the Fall. Specifically, Augustine thought that human nature has been so badly corrupted by original sin that human beings are unable to avoid sin. While human free will remains after the Fall, the power to act virtuously is severely compromised.

Moreover, every person is born sinful and under the condemnation of God. For this reason, divine intervention is necessary to save humanity from damnation.

Of particular importance to Augustinianism is the role of grace. It is only due to grace that human beings are capable of engaging in good works. According to Augustine, grace is irresistible and effectual in the sense that all who are given such grace will surely come to faith in Christ. This is a major theological point, as it essentially establishes a doctrine of predestination within Augustinianism.

Grace is given to those whom God has predestined before the earth began, and is not based on the foreknowledge of God. The predestination in a fully Augustinian system is without any merit in the sinner themselves.

Molinism

Developed by 16th-century Jesuit Luis de Molina, Molinism is a school of thought that is particularly concerned with divine grace and human free will.

Its defining feature is the claim that God knows how a person would freely act in any given situation (middle knowledge, known as scientia media). Molina’s doctrine is called middle knowledge because it falls between the two traditional categories of divine epistemology: natural and free knowledge. It shares characteristics of each and, in the logical order of the divine deliberative process regarding creation, it follows natural knowledge but precedes free knowledge.

Natural knowledge is truth existing independent of God’s acts or choices, and free knowledge is truth dependent on His acts or choices. It is important to note that these forms of knowledge that exist in God are not chronological but logical.

As such, natural knowledge is what “can” happen, middle knowledge is what “would” happen, and free knowledge is what “will” happen. Schematically, natural knowledge means that God knows all possibilities, including necessary truths and everything that could happen, independent of His will or creaturely choices.

Middle knowledge refers to God’s knowledge of what creatures (particularly, human beings) would do in any given circumstance.

Finally, free knowledge is the aspect by which God knows the actual future of the world He decided to create.

Scotism

Along with Thomas Aquinas, Bonaventure, and William of Ockham, Blessed John Duns Scotus is considered among the most important philosopher-theologians in the Catholic tradition.

Scotism, as the school is known, emphasizes the primacy of the will, the univocity of being, and the Immaculate Conception.

Probably the most significant of these teachings is the doctrine of univocity of being. To properly situate this concept, it is helpful to contrast it with Aquinas’s analogy of being (analogia entis).

Aquinas held that God and creation are similar in that they participate in a reality he called “being.” As such, we can know something about God by understanding the created order.

Scotism, while not denying the analogy of being, nonetheless holds to a univocal concept of being. Scotus believed in a common concept of being that is proper to both God and man, though in two radically distinct modes: infinite in God, finite in man.

The argument is that human beings can know something about God because we share in His being.

Personalism

The last school I shall mention is called Personalism. It is also the most recent movement in the Catholic tradition. Unlike the schools of thought mentioned thus far, Personalism is uniquely subjective. The theory was developed most notably by Pope Saint John Paul II and Edith Stein.

In lowering its gaze from God to the human condition, personalists regard the human person as the fundamental concept. As such, it is the individual who gives meaning to all of reality and constitutes its supreme value. Personhood carries with it an inviolable dignity that merits unconditional respect. In a sense, Personalism is the subjective counterbalance to Aquinas’s objectivism.

One can understand the fundamental teaching of Personalism in one of two ways. In a positive aspect, Personalism holds that the human being is a good towards which the only proper and adequate attitude is love. In a negative aspect, Personalism teaches that the person is a good in itself. It follows, therefore, that the person can never be seen as an object or means to an end.

Conclusion

Theology is the study of the nature of God. Because that nature is infinite, theological thought has developed in different ways with different points of emphasis.

Nevertheless, these schools should not be understood as competing for “truth,” but as different lanterns illuminating the same infinite mystery.
