# St. Thomas Aquinas #ST #SCG (c. 1225 – 7 March 1274) was an Italian Dominican friar and priest, the foremost Scholastic thinker, as well one of the most influential philosophers and theologians in the Western tradition. He was from the county of Aquino in the Kingdom of Sicily. Student of [[Albertus Magnus]]. ## Works (1) "Quaestiones disputatae" (Disputed Questions) — These were more complete treatises on subjects that had not been fully elucidated in the lecture halls, or concerning which the professor's opinion had been sought. They are very valuable, because in them the author, free from limitations as to time or space, freely expresses his mind and gives all arguments for or against the opinions adopted. These treatises, containing the questions "De potentia", "De malo", "De spirit. creaturis", "De anima", "De unione Verbi Incarnati", "De virt. in communi", "De caritate", "De corr. fraterna", "De spe", "De virt. cardinal.", "De veritate", were often reprinted, e.g. recently by the Association of St. Paul (2 vols., Paris and Fribourg, Switzerland, 1883). (2) "Quodlibeta" (may be rendered "Various Subjects", or "Free Discussions") — They present questions or arguments proposed and answers given in or outside the lecture halls, chiefly in the more formal Scholastic exercises, termed circuli, conclusiones, or determinationes, which were held once or twice a year. (3) "De unitate intellectus contra Averroistas" -- This opusculum refuted a very dangerous and widespread error, viz., that there was but one soul for all men, a theory which did away with individual liberty and responsibility. (See AVERROES) (4) "Commentaria in Libros Sententiarum" (mentioned above) -- This with the following work are the immediate forerunners of the "Summa theologica". (5) "Summa de veritate catholicae fidei contra gentiles" (Treatise on the Truth of the Catholic Faith, against Unbelievers) -- This work, written at Rome, 1261-64, was composed at the request of St. Raymond of Pennafort, who desired to have a philosophical exposition and defence of the Christian Faith, to be used against the Jews and Moors in Spain. It is a perfect model of patient and sound apologetics, showing that no demonstrated truth (science) is opposed to revealed truth (faith). The best recent editions are those of Rome, 1878 (by Uccelli), of Paris and Fribourg, Switzerland, 1882, and of Rome, 1894. It has been translated into many languages. It is divided into four books: I. Of God as He is in Himself; II. Of God the Origin of Creatures; III. Of God the End of Creatures; IV. Of God in His Revelation. It is worthy of remark that the Fathers of the Vatican Council, treating the necessity of revelation (Constitution "Dei Filius", c. 2), employed almost the very words used by St. Thomas in treating that subject in this work (I, cc. iv, V), and in the "Summa theologica" (I:1:1). (6) Three works written by order of Urban IV -- - The "Opusculum contra errores Graecorum" refuted the errors of the Greeks on doctrines in dispute between them and the Roman Church, viz., the procession of the Holy Ghost from the Father and the Son, the primacy of the Roman pontiff, the Holy Eucharist, and purgatory. It was used against the Greeks with telling effect in the Council of Lyons (1274) and in the Council of [[Florence]] (1493). In the range of human reasonings on deep subjects there can be found nothing to surpass the sublimity and depth of the argument adduced by St. Thomas to prove that the Holy Ghost proceeds from the Father and the Son (cf. Summa I:36:2); but it must be borne in mind that our Faith is not based on that argument alone. - "Officium de festo Corporis Christi". Mandonnet (Ecrits, p. 127) declares that it is now established beyond doubt that St. Thomas is the author of the beautiful Office of Corpus Christi, in which solid doctrine, tender piety, and enlightening Scriptural citations are combined, and expressed in language remarkably accurate, beautiful, chaste, and poetic. Here we find the well-known hymns, "Sacris Solemniis", "Pange Lingua" (concluding in the "Tantum Ergo"), "Verbum Supernum" (concluding with the "O Salutaris Hostia") and, in the Mass, the beautiful sequence "Lauda Sion". In the responses of the office, St. Thomas places side by side words of the New Testament affirming the real presence of Christ in the Blessed Sacrament and texts from the Old Testament referring to the types and figures of the Eucharist. Santeuil, a poet of the seventeenth century, said he would give all the verses he had written for the one stanza of the "Verbum Supernum": "Se nascens dedit socium, convescens in edulium: Se moriens in pretium, Se regnans dat in praemium" — "In birth, man's fellow-man was He, His meat, while sitting at the Board: He died his Ransomer to be, He reigns to be his Great Reward" (tr. by Marquis of Bute). Perhaps the gem of the whole office is the antiphon "O Sacrum Convivium" (cf. Conway, "St. Thomas Aquinas", London and New York, 1911, p. 61). - The "Catena Aurea", though not as original as his other writings, furnishes a striking proof of St. Thomas's prodigious memory and manifests an intimate acquaintance with the Fathers of the Church. The work contains a series of passages selected from the writings of the various Fathers, arranged in such order that the texts cited form a running commentary on the Gospels. The commentary on St. Matthew was dedicated to Urban IV. An English translation of the "Catena Aurea" was edited by John Henry Newman (4 vols., Oxford, 1841-1845; see Vaughan, op. cit., vol. II,) pp. 529 sqq.. (7) The "Summa theologica"-- This work immortalized St. Thomas. The author himself modestly considered it simply a manual of Christian doctrine for the use of students. In reality it is a complete scientifically arranged exposition of theology and at the same time a summary of Christian philosophy. In the brief prologue St. Thomas first calls attention to the difficulties experienced by students of sacred doctrine in his day, the causes assigned being: the multiplication of useless questions, articles, and arguments; the lack of scientific order; frequent repetitions, "which beget disgust and confusion in the minds of learners". Then he adds: "Wishing to avoid these and similar drawbacks, we shall endeavour, confiding in the Divine assistance, to treat of these things that pertain to sacred doctrine with brevity and clearness, in so far as the subject to be treated will permit." In the introductory question, "On Sacred Doctrine", he proves that, besides the knowledge which reason affords, Revelation also is necessary for salvation first, because without it men could not know the supenatural end to which they must tend by their voluntary acts; secondly, because, without Revelation, even the truths concerning God which could be proved by reason would be known "only by a few, after a long time, and with the admixture of many errors". When revealed truths have been accepted, the mind of man proceeds to explain them and to draw conclusions from them. Hence results theology, which is a science, because it proceeds from principles that are certain (Answer 2). The object, or subject, of this science is God; other things are treated in it only in so far as they relate to God (Answer 7). Reason is used in theology not to prove the truths of faith, which are accepted on the authority of God, but to defend, explain, and develop the doctrines revealed (Answer 8). He thus announces the division of the "Summa": "Since the chief aim of this sacred science is to give the knowledge of God, not only as He is in Himself, but also as He is the Beginning of all things, and the End of all, especially of rational creatures, we shall treat first of God; secondly, of the rational creature's advance towards God (de motu creaturae rationalis in Deum); thirdly, of Christ, Who, as Man, is the way by which we tend to God." God in Himself, and as He is the Creator; God as the End of all things, especially of man; God as the Redeemer — these are the leading ideas, the great headings, under which all that pertains to theology is contained.
