A Model of Devotion, a Model for the

Priesthood

We have already seen the breadth of the Universal Doctor’s intellect,

In his 1923 encyclical Studiorum Ducem, Pope Pius XI offers St. Thomas Aquinas as the
model theologian, especially for priests and seminarians. Aquinas embraced his call to
the priesthood to the fullest. He put his knowledge and gifts into practice as a Dominican
Friar and ordered his life toward living out his vocation.
Perhaps most lauded by Pius XI is Aquinas’ devotion to Sacred Scripture.

“Everything he wrote was securely based upon Holy Scripture and that was the
foundation upon which he built.” —Pope Pius XI, Studiorum Ducem.
As a devout saint, Aquinas studied Scripture as a way to come to God. As a devout
priest, he kept others from error by defending the authority and historicity of the Bible,
explaining the literal and spiritual senses, and writing detailed commentaries on the
Gospels.

Aquinas acts as a guide for priests and seminarians as much today as he did a century
ago. His works are again being held up for study and are being made more widely
available by scholars like those at the Aquinas Institute for the Study of Sacred
Doctrine, in partnership with us at the St. Paul Center.
Why Pope Pius XI Pointed to Aquinas as the Model for Seminarians
2. Such a combination of doctrine and piety, of erudition and virtue, of truth and charity,
is to be found in an eminent degree in the angelic Doctor and it is not without reason that
he has been given the sun for a device; for he both brings the light of learning into the
minds of men and fires their hearts and wills with the virtues. God, the Source of all
sanctity and wisdom would, therefore, seem to have desired to show in the case of
Thomas how each of these qualities assists the other, how the practice of the virtues
disposes to the contemplation of truth, and the profound consideration of truth in turn
gives luster and perfection to the virtues. For the man of pure and upright life, whose
passions are controlled by virtue, is delivered as it were of a heavy burden and can
much more easily raise his mind to heavenly things and penetrate more profoundly into
the secrets of God, according to the maxim of Thomas himself: “Life comes before
learning: for life leads to the knowledge of truth” (Comment. in Matth., v); and if such a
man devotes himself to the investigation of the supernatural, he will find a powerful
incentive in such a pursuit to lead a perfect life; for the learning of such sublime things,
the beauty of which is a ravishing ecstasy, so far from being a solitary or sterile
occupation, must be said to be on the contrary most practical.

Thomas possessed all the moral virtues to a very high degree and so closely bound
together that, as he himself insists should be the case, they formed one whole in charity
“which informs the acts of all the virtues” (II-II, xxiii, 8; I-II, Ixv). If, however, we seek to
discover the peculiar and specific characteristics of his sanctity, there occurs to Us in the
first place that virtue which gives Thomas a certain likeness to the angelic natures, and
that is chastity; he preserved it unsullied in a crisis of the most pressing danger and was
therefore considered worthy to be surrounded by the angels with a mystic girdle.

This perfect regard for purity was accompanied at the same time by an equal aversion
for fleeting possessions and a contempt for honors; it is recorded that his firmness of
purpose overcame the obstinate persistence of relatives who strove their utmost to
induce him to accept a lucrative situation in the world and that later, when the Supreme
Pontiff would have offered him a mitre, his prayers were successful in securing that such
a dread burden should not be laid upon him. The most distinctive feature, however, of
the sanctity of Thomas is what St. Paul describes as the “word of wisdom” (I Cor. xii, 8)
and that combination of the two forms of wisdom, the acquired and the infused, as they
are termed, with which nothing accords so well as humility, devotion to prayer 12. In
dealing orally or in writing with divine things, he provides theologians with a striking
example of the intimate connection which should exist between the spiritual and the
intellectual life. For just as a man cannot really be said to know some distant country, if
his acquaintance is confined merely to a description of it, however accurate, but must
have dwelt in it for some time; so nobody can attain to an intimate knowledge of God by
mere scientific investigation, unless he also dwells in the most intimate association with
God. The aim of the whole theology of St. Thomas is to bring us into close living intimacy
with God. For even as in his childhood at Monte Cassino he unceasingly put the
question: “What is God?”; so all the books he wrote concerning the creation of the world,
the nature of man, laws, the virtues, and the sacraments, are all concerned with God,
the Author of eternal salvation.

14. He not only instructs us by his example how to pursue such a diversity of studies, but
also teaches us firm and enduring principles of each single science. For, in the first
place, who has provided a better explanation than he of the nature and character of
philosophy, its various divisions and the relative importance of each? Consider how
clearly he demonstrates the congruence and harmony between all the various sections
which go to make up the body as it were of this science. “It is the function of the wise
man,” he declares, “to put things in order, because wisdom is primarily the perfection of
reason and it is the characteristic of reason to know order; for although the sensitive
faculties know some things absolutely, only the intellect or reason can know the relation
one thing bears to another. The sciences, therefore, vary according to the various forms
of order which reason perceives to be peculiar to each. The order which the
consideration of reason establishes in its own peculiar activity pertains to rational
philosophy or logic, whose function is to consider the order of the parts of speech in their
mutual relations and in relation to the conclusions which may be drawn from them. It is
for natural philosophy or physics to consider the order in things which human reason
considers but does not itself institute, so that under natural philosophy we include also
metaphysics. But the order of voluntary acts is for the consideration of moral philosophy
which is divided into three sections: the first considers the activities of the individual man
in relation to their end and is called ‘monastics’; the second considers the activities of
the family group or community and is called economics; the third considers the activities
of the State and is called politics” (Ethics, I, I). Thomas dealt thoroughly with all these
several divisions of philosophy, each according to its appropriate method, and,
beginning with things nearest to our human reason, rose step by step to things more
remote until he stood in the end on “the topmost peak of all things” (Contra Gentes, II,
lvi; IV, i).
26. But inasmuch as St. Thomas has been duly proclaimed patron of all Catholic schools
because he marvelously combined both forms of wisdom, the rational and the divinely
inspired, because he had recourse to prayer and fasting to solve the most difficult
problems, because he used the image of Christ crucified in place of all books, let him be
a model also for seminarians, so that they may learn how to pursue their studies to the
best advantage and with the greatest profit to themselves. Members of religious
communities should look upon the life of St. Thomas as upon a mirror; he refused even
the highest dignities offered to him in order to live in the practice of the most perfect
obedience and to die in the sanctity of his profession. Let all the Faithful of Christ take
the Angelic Doctor as a model of devotion to the august Queen of Heaven, for it was his
custom often to repeat the “Hail Mary” and to inscribe the sweet Name upon his pages,
and let them ask the Doctor of the Eucharist himself to inspire them with love for the
divine Sacrament. Priests above all will be zealous in so doing, as is only proper.
