The Life of St. Thomas Aquinas
Daniel Kennedy
The great outlines and all the important events of St. Thomas Aquinas’ life are known,
but biographers differ as to some details and dates. Death prevented Henry Denifle
from executing his project of writing a critical life of the saint. Denifle’s friend
and pupil, Dominic Prümmer, O.P., professor of theology in the University of Fribourg,
Switzerland, took up the work and published the “Fontes Vitae S. Thomae Aquinatis, notis
historicis et criticis illustrati”; and the first fascicle (Toulouse, 1911) has appeared, giving
the life of St. Thomas by Peter Calo (1300) now published for the first time. From Tolomeo
of Lucca . . . we learn that at the time of the saint’s death there was a doubt about his exact
age (Prümmer, op. cit., 45). The end of 1225 is usually assigned as the time of his birth.
Father Prümmer, on the authority of Calo, thinks 1227 is the more probable date (op. cit.,
28). All agree that he died in 1274.
Landulph, his father, was Count of Aquino; Theodora, his mother, Countess of Teano.
His family was related to the Emperors Henry VI and Frederick II, and to the Kings of
Aragon, Castile, and France. Calo relates that a holy hermit foretold his career, saying to
Theodora before his birth: “He will enter the Order of Friars Preachers, and so great will be
his learning and sanctity that in his day no one will be found to equal him” (Prümmer, op.
cit., 18). At the age of five, according to the custom of the times, he was sent to receive his
first training from the Benedictine monks of Monte Cassino. Diligent in study, he was thus
early noted as being meditative and devoted to prayer, and his preceptor was surprised at
hearing the child ask frequently: “What is God?”
About the year 1236 he was sent to the University of Naples. Calo says that the change
was made at the instance of the Abbot of Monte Cassino, who wrote to Thomas’s father
that a boy of such talents should not be left in obscurity (Prümmcr, op. cit., 20). At Naples
his preceptors were Pietro Martini and Petrus Hibernus. The chronicler says that he soon
surpassed Martini at grammar, and he was then given over to Peter of Ireland, who trained
him in logic and the natural sciences. The customs of the times divided the liberal arts
into two courses: the Trivium, embracing grammar, logic, and rhetoric; the Quadrivium,
comprising music, mathematics, geometry, and astronomy . . . . Thomas could repeat the
lessons with more depth and lucidity than his masters displayed. The youth’s heart had
remained pure amidst the corruption with which he was surrounded, and he resolved to
embrace the religious life.
Some time between 1240 and August, 1243, he received the habit of the Order of St.
Dominic, being attracted and directed by John of St. Julian, a noted preacher of the convent
of Naples. The city wondered that such a noble young man should don the garb of poor friar.
His mother, with mingled feelings of joy and sorrow, hastened to Naples to see her son. The
Dominicans, fearing she would take him away, sent him to Rome, his ultimate destination
being Paris or Cologne. At the instance of Theodora, Thomas’s brothers, who were soldiers
under the Emperor Frederick, captured the novice near the town of Aquapendente and confined him in the fortress of San Giovanni at Rocca Secca. Here he was detained nearly
two years, his parents, brothers, and sisters endeavouring by various means to destroy his
vocation. The brothers even laid snares for his virtue, but the pure-minded novice drove
the temptress from his room with a brand which he snatched from the fire. Towards the end
of his life, St. Thomas confided to his faithful friend and companion, Reginald of Piperno,
the secret of a remarkable favour received at this time. When the temptress had been driven
from his chamber, he knelt and most earnestly implored God to grant him integrity of mind
and body. He fell into a gentle sleep, and, as he slept, two angels appeared to assure him
that his prayer had been heard. They then girded him about with a white girdle, saying:
“We gird thee with the girdle of perpetual virginity.” And from that day forward he never
experienced the slightest motions of concupiscence.
The time spent in captivity was not lost. His mother relented somewhat, after the first
burst of anger and grief; the Dominicans were allowed to provide him with new habits,
and through the kind offices of his sister he procured some books — the Holy Scriptures,
Aristotle’s Metaphysics, and the “Sentences” of Peter Lombard. After eighteen months
or two years spent in prison, either because his mother saw that the hermit’s prophecy
would eventually be fulfilled or because his brothers feared the threats of Innocent IV
and Frederick II, he was set at liberty, being lowered in a basket into the arms of the
Dominicans, who were delighted to find that during his captivity “he had made as much
progress as if he had been in a studium generale” (Calo, op. cit., 24).
Thomas immediately pronounced his vows, and his superiors sent him to Rome. Innocent
IV examined closely into his motives in joining the Friars Preachers, dismissed him with a
blessing, and forbade any further interference with his vocation. John the Teutonic, fourth
master general of the order, took the young student to Paris and, according to the majority
of the saint’s biographers, to Cologne, where he arrived in 1244 or 1245, and was placed
under Albertus Magnus, the most renowned professor of the order. In the schools Thomas’s
humility and taciturnity were misinterpreted as signs of dullness, but when Albert had
heard his brilliant defence of a difficult thesis, he exclaimed: “We call this young man a
dumb ox, but his bellowing in doctrine will one day resound throughout the world.”
In 1245 Albert was sent to Paris, and Thomas accompanied him as a student. In 1248
both returned to Cologne. Albert had been appointed regent of the new studium generale,
erected that year by the general chapter of the order, and Thomas was to teach under
him as Bachelor. (On the system of graduation in the thirteenth century see ORDER OF
PREACHERS — II, A, 1, d). During his stay in Cologne, probably in 1250, he was raised
to the priesthood by Conrad of Hochstaden, archbishop of that city. Throughout his busy
life, he frequently preached the Word of God, in Germany, France, and Italy. His sermons
were forceful, redolent of piety, full of solid instruction, abounding in apt citations from
the Scriptures.
In the year 1251 or 1252 the master general of the order, by the advice of Albertus
Magnus and Hugo a S. Charo (Hugh of St. Cher), sent Thomas to fill the office of Bachelor
(sub-regent) in the Dominican studium at Paris. This appointment may be regarded as the
beginning of his public career, for his teaching soon attracted the attention both of the
professors and of the students. His duties consisted principally in explaining the “Sentences”
of Peter Lombard, and his commentaries on that text-book of theology furnished the
materials and, in great part, the plan for his chief work, the “Summa theologica”.
In due time he was ordered to prepare himself to obtain the degree of Doctor in Theology
from the University of Paris, but the conferring of the degree was postponed, owing to a
dispute between the university and the friars. The conflict, originally a dispute between
the university and the civic authorities, arose from the slaying of one of the students and the wounding of three others by the city guard. The university, jealous of its autonomy,
demanded satisfaction, which was refused. The doctors closed their schools, solemnly
swore that they would not reopen them until their demands were granted, and decreed
that in future no one should be admitted to the degree of Doctor unless he would take an
oath to follow the same line of conduct under similar circumstances. The Dominicans and
Franciscans, who had continued to teach in their schools, refused to take the prescribed
oath, and from this there arose a bitter conflict which was at its height when St. Thomas
and St. Bonaventure were ready to be presented for their degrees. William of St-Amour
extended the dispute beyond the original question, violently attacked the friars, of whom he
was evidently jealous, and denied their right to occupy chairs in the university. Against his
book, “De periculis novissimorum temporum” (The Perils of the Last Times), St. Thomas
wrote a treatise “Contra impugnantes religionem”, an apology for the religious orders
(Touron, op. cit., II, cc. vii sqq.). The book of William of St-Amour was condemned by
Alexander IV at Anagni, 5 October, 1256, and the pope gave orders that the mendicant
friars should be admitted to the doctorate.
About this time St. Thomas also combated a dangerous book, “The Eternal Gospel”
(Touron, op. cit., II, cxii). The university authorities did not obey immediately; the
influence of St. Louis IX and eleven papal Briefs were required before peace was firmly
established, and St. Thomas was admitted to the degree of Doctor in Theology. The date
of his promotion, as given by many biographers, was 23 October, 1257. His theme was
“The Majesty of Christ”. His text, “Thou waterest the hills from thy upper rooms: the earth
shall be filled with the fruit of thy works” (Psalm 103:13), said to have been suggested
by a heavenly visitor, seems to have been prophetic of his career. A tradition says that St.
Bonaventure and St. Thomas received the doctorate on the same day, and that there was a
contest of humility between the two friends as to which should be promoted first.
From this time St. Thomas’s life may be summed up in a few words: praying, preaching,
teaching, writing, journeying. Men were more anxious to hear him than they had been
to hear Albert, whom St. Thomas surpassed in accuracy, lucidity, brevity, and power of
exposition, if not in universality of knowledge. Paris claimed him as her own; the popes
wished to have him near them; the studia of the order were eager to enjoy the benefit of
his teaching; hence we find him successively at Anagni, Rome, Bologna, Orvieto, Viterbo,
Perugia, in Paris again, and finally in Naples, always teaching and writing, living on earth
with one passion, an ardent zeal for the explanation and defence of Christian truth. So
devoted was he to his sacred task that with tears he begged to be excused from accepting
the Archbishopric of Naples, to which he was appointed by Clement IV in 1265. Had this
appointment been accepted, most probably the “Summa theologica” would not have been
written.
Yielding to the requests of his brethren, he on several occasions took part in the
deliberations of the general chapters of the order. One of these chapters was held in London
in 1263. In another held at Valenciennes (1259) he collaborated with Albertus Magnus and
Peter of Tarentasia (afterwards Pope Innocent V) in formulating a system of studies which
is substantially preserved to this day in the studia generalia of the Dominican Order (cf.
Douais, op. cit.).
It is not surprising to read in the biographies of St. Thomas that he was frequently
abstracted and in ecstasy. Towards the end of his life the ecstasies became more frequent.
On one occasion, at Naples in 1273, after he had completed his treatise on the Eucharist,
three of the brethren saw him lifted in ecstasy, and they heard a voice proceeding from the
crucifix on the altar, saying “Thou hast written well of me, Thomas; what reward wilt thou
have?” Thomas replied, “None other than Thyself, Lord” (Prümmer, op. cit., p. 38). Similar declarations are said to have been made at Orvieto and at Paris.
On 6 December, 1273, he laid aside his pen and would write no more. That day he
experienced an unusually long ecstasy during Mass; what was revealed to him we can only
surmise from his reply to Father Reginald, who urged him to continue his writings: “I can
do no more. Such secrets have been revealed to me that all I have written now appears to
be of little value” (modica, Prümmer, op. cit., p. 43). The “Summa theologica” had been
completed only as far as the ninetieth question of the third part (De partibus poenitentiae).
Thomas began his immediate preparation for death. Gregory X, having convoked a
general council, to open at Lyons on 1 May, 1274, invited St. Thomas and St. Bonaventure
to take part in the deliberations, commanding the former to bring to the council his treatise
“Contra errores Graecorum” (Against the Errors of the Greeks). He tried to obey, setting
out on foot in January, 1274, but strength failed him; he fell to the ground near Terracina,
whence he was conducted to the Castle of Maienza, the home of his niece the Countess
Francesca Ceccano. The Cistercian monks of Fossa Nuova pressed him to accept their
hospitality, and he was conveyed to their monastery, on entering which he whispered to
his companion: “This is my rest for ever and ever: here will I dwell, for I have chosen it”
(Psalm 131:14). When Father Reginald urged him to remain at the castle, the saint replied:
“If the Lord wishes to take me away, it is better that I be found in a religious house than
in the dwelling of a lay person.” The Cistercians were so kind and attentive that Thomas’s
humility was alarmed. “Whence comes this honour”, he exclaimed, “that servants of God
should carry wood for my fire!” At the urgent request of the monks he dictated a brief
commentary on the Canticle of Canticles.
The end was near; extreme unction was administered. When the Sacred Viaticum was
brought into the room he pronounced the following act of faith:
If in this world there be any knowledge of this sacrament stronger than that of faith, I
wish now to use it in affirming that I firmly believe and know as certain that Jesus Christ,
True God and True Man, Son of God and Son of the Virgin Mary, is in this Sacrament . . .
I receive Thee, the price of my redemption, for Whose love I have watched, studied, and
laboured. Thee have I preached; Thee have I taught. Never have I said anything against
Thee: if anything was not well said, that is to be attributed to my ignorance. Neither do I
wish to be obstinate in my opinions, but if I have written anything erroneous concerning
this sacrament or other matters, I submit all to the judgment and correction of the Holy
Roman Church, in whose obedience I now pass from this life.
He died on 7 March, 1274. Numerous miracles attested his sanctity, and he was
canonized by John XXII, 18 July, 1323. The monks of Fossa Nuova were anxious to keep
his sacred remains, but by order of Urban V the body was given to his Dominican brethren,
and was solemnly translated to the Dominican church at Toulouse, 28 January, 1369. A
magnificent shrine erected in 1628 was destroyed during the French Revolution, and the
body was removed to the Church of St. Sernin, where it now reposes in a sarcophagus of
gold and silver, which was solemnly blessed by Cardinal Desprez on 24 July, 1878. The
chief bone of his left arm is preserved in the cathedral of Naples. The right arm, bestowed
on the University of Paris, and originally kept in the St. Thomas’s Chapel of the Dominican
church, is now preserved in the Dominican Church of S. Maria Sopra Minerva in Rome,
whither it was transferred during the French Revolution.
A description of the saint as he appeared in life is given by Calo (Prümmer, op. cit., p.
401), who says that his features corresponded with the greatness of his soul. He was of lofty
stature and of heavy build, but straight and well proportioned. His complexion was “like
the colour of new wheat”: his head was large and well shaped, and he was slightly bald.
All portraits represent him as noble, meditative, gentle yet strong. St. Pius V proclaimed
