The Magi were astronomers. Really.

The three Magi really were astronomers. This is clever depiction of them from the Vatican Observatory's homepage:

River Forest & Æterni Patris

From Edward Feser's "The Thomistic Tradition (part 1)" (vide also part 2):

This approach emphasizes the Aristotelian foundations of Aquinas’s philosophy, and in particular the idea that the construction of a sound metaphysics must be preceded by a sound understanding of natural science, as interpreted in light of an Aristotelian philosophy of nature. Accordingly, it is keen to show that modern physical science can and should be given such an interpretation. Charles De Koninck (1906-1965), James A. Weisheipl (1923-1984), William A. Wallace, and Benedict Ashley are among its representatives. It is sometimes called “Laval Thomism” after the University of Laval in Quebec [which produced this brilliant thesis: Thomism and Mathematical Physics], where De Koninck was a professor. The alternative label “River Forest Thomism” derives from a suburb of Chicago, the location of the Albertus Magnus Lyceum for Natural Science, whose members are associated with this approach. It is also sometimes called “Aristotelian Thomism” (to highlight its contrast with Gilson’s brand of existential Thomism) though since Neo-Scholastic Thomism also emphasizes Aquinas’s continuity with Aristotle, this label seems a bit too proprietary. (There are writers, like the contemporary Thomist Ralph McInerny, who exhibit both Neo-Scholastic and Laval/River Forest influences, and the approaches are not necessarily incompatible.)

E.g., Heisenberg recognized in his Physics and Philosophy that the probability wave concept in quantum mechanics "was a quantitative version of the concept of 'potentia' in Aristotelian philosophy" (p. 41) and that the "concept of the soul for instance in the philosophy of Thomas Aquinas was more natural and less forced than the Cartesian concept of 'res cogitans,' even if we are convinced that the laws of physics and chemistry are strictly valid in living organisms." (p. 80). Pope Leo XIII, who was trained in the natural sciences as well as in theology, wrote in 1879 that the study of the natural sciences is epistemologically prior to that of theology, viz., that knowledge of immaterial things for us comes after that of material things:

30. And here it is well to note that our philosophy can only by the grossest injustice be accused of being opposed to the advance and development of natural science. For, when the Scholastics, following the opinion of the holy Fathers, always held in anthropology that the human intelligence is only led to the knowledge of things without body and matter by things sensible, they well understood that nothing was of greater use to the philosopher than diligently to search into the mysteries of nature and to be earnest and constant in the study of physical things. And this they confirmed by their own example; for St. Thomas, Blessed Albertus Magnus, and other leaders of the Scholastics were never so wholly rapt in the study of philosophy as not to give large attention to the knowledge of natural things; and, indeed, the number of their sayings and writings on these subjects, which recent professors approve of and admit to harmonize with truth, is by no means small. Moreover, in this very age many illustrious professors of the physical sciences openly testify that between certain and accepted conclusions of modern physics and the philosophic principles of the schools there is no conflict worthy of the name.
