Saint Thomas Aquinas was one of the most brilliant and influential theologians and philosophers in the history of the Catholic Church, born in Roccasecca, Italy, into a noble family. Going against the interests of his relatives, who wanted him to be the abbot of Monte Cassino and even held him captive, he joined the Order of Dominicans in 1244, dedicating himself entirely to study and the spiritual life. Sent to Paris and Cologne, he became the most notable disciple of Saint Albert the Great, achieving the degree of master in theology in the year 1256. His earthly journey, which ended in the year 1274, was consumed by the tireless search for harmony between faith and reason, building the monumental philosophical-theological synthesis known as Thomism. Besides his immense intellectual stature expressed in the Summa Theologiae, he cultivated a deep and tender Eucharistic devotion, composing, at the Pope's request, the immortal liturgical hymns for the feast of Corpus Christi. Canonized in 1323 by Pope John XXII and declared a Doctor of the Church in 1567, his life proved that the highest erudition only reaches its summit when illuminated by a humble, submissive, and awe-filled sanctity before the mystery of divine revelation.
📖 Introit (Ecclus 15:5 | Ps 91:2)
In medio Ecclesiae aperuit os ejus: et implevit eum Dominus spiritu sapientiae et intellectus: stolam gloriae induit eum. Bonum est confiteri Domino: et psallere nomini tuo, Altissime.
In the midst of the Church the Lord opened his mouth: and filled him with the spirit of wisdom and understanding: and clothed him with a robe of glory. It is good to give praise to the Lord: and to sing to thy name, O Most High.
📜 Reading (Wis 7:7-14)
Optavi, et datus est mihi sensus: et invocavi, et venit in me spiritus sapientiae: et praeposui illam regnis et sedibus, et divitias nihil esse duxi in comparatione illius. Nec comparavi illi lapidem pretiosum: quoniam omne aurum in comparatione illius arena est exigua, et tamquam lutum aestimabitur argentum in conspectu illius. Super salutem et speciem dilexi illam, et proposui pro luce habere illam: quoniam inextinguibile est lumen illius. Venerunt autem mihi omnia bona pariter cum illa, et innumerabilis honestas per manus illius, et laetatus sum in omnibus: quoniam antecedebat me ista sapientia, et ignorabam quoniam horum omnium mater est. Quam sine fictione didici, et sine invidia communico, et honestatem illius non abscondo. Infinitus enim thesaurus est hominibus: quo qui usi sunt, participes facti sunt amicitiae Dei, propter disciplinae dona commendati.
I wished, and understanding was given me: and I called upon God, and the spirit of wisdom came upon me: and I preferred her before kingdoms and thrones, and esteemed riches nothing in comparison of her. Neither did I compare unto her any precious stone: for all gold in comparison of her, is as a little sand, and silver in respect to her shall be counted as clay. I loved her above health and beauty, and chose to have her instead of light: for her light cannot be put out. Now all good things came to me together with her, and innumerable riches through her hands, and I rejoiced in all these: for this wisdom went before me, and I knew not that she was the mother of them all. Which I have learned without guile, and communicate without envy, and her riches I hide not. For she is an infinite treasure to men: which they that use, become the friends of God, being commended for the gifts of discipline.
✝️ Gospel (Mt 5:13-19)
In illo tempore: Dixit Jesus discipulis suis: Vos estis sal terrae. Quod si sal evanuerit, in quo salietur? Ad nihilum valet ultra, nisi ut mittatur foras, et conculcetur ab hominibus. Vos estis lux mundi. Non potest civitas abscondi supra montem posita, neque accendunt lucernam, et ponunt eam sub modio, sed super candelabrum, ut luceat omnibus, qui in domo sunt. Sic luceat lux vestra coram hominibus, ut videant opera vestra bona, et glorificent Patrem vestrum, qui in caelis est. Nolite putare, quoniam veni solvere legem, aut prophetas: non veni solvere, sed adimplere. Amen quippe dico vobis, donec transeat caelum et terra, jota unum, aut unus apex non praeteribit a lege, donec omnia fiant. Qui ergo solverit unum de mandatis istis minimis, et docuerit sic homines, minimus vocabitur in regno caelorum: qui autem fecerit, et docuerit, hic magnus vocabitur in regno caelorum.
At that time, Jesus said to his disciples: You are the salt of the earth. But if the salt lose its savour, wherewith shall it be salted? It is good for nothing any more but to be cast out, and to be trodden on by men. You are the light of the world. A city seated on a mountain cannot be hid. Neither do men light a candle and put it under a bushel, but upon a candlestick, that it may shine to all that are in the house. So let your light shine before men, that they may see your good works, and glorify your Father who is in heaven. Do not think that I am come to destroy the law, or the prophets. I am not come to destroy, but to fulfill. For amen I say unto you, till heaven and earth pass, one jot, or one tittle shall not pass of the law, till all be fulfilled. He therefore that shall break one of these least commandments, and shall so teach men, shall be called the least in the kingdom of heaven. But he that shall do and teach, he shall be called great in the kingdom of heaven.
💡 The light of reason and the splendor of divine faith
The vocation of a Doctor of the Church is to be the perfect echo of God's voice, fulfilling what the introit proclaims when it states that the Lord opened his mouth in the midst of the assembly to fill him with intellect and wisdom. Saint Thomas Aquinas, commenting on this Gospel in his Catena Aurea, teaches that the salt of the earth represents evangelical preaching, whose property is to preserve souls from the corruption of sin and to confer true savor to human moral life. At the same time, the light placed on the candlestick is the splendid manifestation of theological truth that dispels the darkness of ignorance. He who teaches and practices the commandments, bringing the law to its full completion without abolishing a single jot, becomes great in the Kingdom of Heaven precisely because his intelligence allows itself to be molded by the uncreated light, illuminating the entire house of the Church with the crystalline clarity of pure doctrine.
This extraordinary intellectual illumination does not come from isolated human effort, but from persevering prayer that draws upon the soul the infused gift of the Holy Spirit, as the sacred epistle attests. In the Summa Theologiae (II-II, q. 45), the Angelic Doctor explains that wisdom is simultaneously an acquired intellectual virtue and a divine gift that allows one to judge heavenly things through a certain connaturality with God, a direct fruit of charity. By preferring this infinite wisdom to thrones, riches, and fleeting beauties, the soul clothes itself with the robe of glory mentioned in the introit. The inexhaustible treasure that makes men partakers of divine friendship is achieved when the mind empties itself of earthly vanities and asks of God only God Himself, receiving in addition all goods through the inextinguishable light that guides reason to the contemplation of the First Truth.
The glory of Christian wisdom resides, therefore, in the inseparable union between the light that shines before men in good works and the interior and hidden treasure of friendship with God. The theological testimony of Saint Thomas demonstrates that divine grace does not destroy nature, but elevates and perfects it, transforming the purified human understanding into an imperturbable beacon for the Catholic faith. Whoever is nourished by the spirit of understanding becomes the salt that preserves the integrity of revelation and the light that guides hearts, glorifying the heavenly Father through a doctrine that is, in itself, a continuous act of praise, service, and adoration to the Most High.
