Happy Feast of St. Thomas Aquinas! We have already sent an e-mail to Thomas, the winner of the NovAntiqua Summa Giveaway 2011, to let him know how to claim his volume of the NovAntiqua Summa. (And let me assure our readers that it is entirely coincidental that the winner’s name is Thomas.)

In honor of the Feast, I wanted to post an excerpt from one of Pope Benedict XVI’s Wednesday audiences last year in which he treated St. Thomas Aquinas:

Faith consolidates, integrates and illumines the heritage of truth that human reason acquires. The trust with which St Thomas endows these two instruments of knowledge, faith and reason, may be traced back to the conviction that both stem from the one source of all truth, the divine Logos, which is active in both contexts, that of Creation and that of redemption.

Together with the agreement between reason and faith, we must recognize on the other hand that they avail themselves of different cognitive procedures. Reason receives a truth by virtue of its intrinsic evidence, mediated or unmediated; faith, on the contrary, accepts a truth on the basis of the authority of the Word of God that is revealed. St Thomas writes at the beginning of his Summa Theologiae: “We must bear in mind that there are two kinds of sciences. There are some which proceed from a principle known by the natural light of the intelligence, such as arithmetic and geometry and the like. There are some which proceed from principles known by the light of a higher science: thus the science of perspective proceeds from principles established by geometry, and music from principles established by arithmetic. So it is that sacred doctrine is a science, because it proceeds from principles established by the light of a higher science, namely, the science of God and the blessed” (ia, q. 1, a.2).

This distinction guarantees the autonomy of both the human and the theological sciences. However, it is not equivalent to separation but, rather, implies a reciprocal and advantageous collaboration. Faith, in fact, protects reason from any temptation to distrust its own abilities, stimulates it to be open to ever broader horizons, keeps alive in it the search for foundations and, when reason itself is applied to the supernatural sphere of the relationship between God and man, faith enriches his work. According to St Thomas, for example, human reason can certainly reach the affirmation of the existence of one God, but only faith, which receives the divine Revelation, is able to draw from the mystery of the Love of the Triune God.

Moreover, it is not only faith that helps reason. Reason too, with its own means can do something important for faith, making it a threefold service which St Thomas sums up in the preface to his commentary on the De Trinitate of Boethius: “demonstrating those truths that are preambles of the faith; giving a clearer notion, by certain similitudes, of the truths of the faith; resisting those who speak against the faith, either by showing that their statements are false, or by showing that they are not necessarily true” (q. 2, a.3). The entire history of theology is basically the exercise of this task of the mind which shows the intelligibility of faith, its articulation and inner harmony, its reasonableness and its ability to further human good. The correctness of theological reasoning and its real cognitive meaning is based on the value of theological language which, in St Thomas’ opinion, is principally an analogical language. The distance between God, the Creator, and the being of his creatures is infinite; dissimilitude is ever greater than similitude (cf. DS 806). Nevertheless in the whole difference between Creator and creatures an analogy exists between the created being and the being of the Creator, which enables us to speak about God with human words.
