Saint Thomas Aquinas Writings

The writings of Thomas may be classified as, (1) exegetical, homiletical, and liturgical; (2) dogmatic, apologetic, and ethical; and (3) philosophical. Among the genuine works of the first class were: Commentaries on Job (1261-65); on Psalms, according to some a reportatum, or report of oral deliverances furnished by his companion Raynaldus; on Isaiah; the Catena aurea, which is a running commentary on the four Gospels, constructed on numerous citations from the Fathers; probably a Commentary on Canticles, and on Jeremiah; and wholly or partly reportata, on John, on Matthew, and on the epistles of Paul, including, according to one authority, Hebrews i.-x. Thomas prepared for Urban IV., Officium de corpore Christi (1264); and the following works may be either genuine or reportata: Expositio angelicce salutationis; Tractatus de decem praeceptis; Orationis dominico expositio; Sermones pro dominicis diebus et pro sanctorum solemnitatibus; Sermones de angelis, and Sermones de quadragesima. Of his sermons only manipulated copies are extant. In the second division were: In quatitor sententiarum libros, of his first Paris sojourn; Questiones disputatce, written at Paris and Rome; Questiones quodlibetales duodecini; Summa catholicce fidei contra gentiles (1261-C,4); and the Summa theologioe. To the dogmatic works belong also certain commentaries, as follows: Expositio in librum beati Dionysii de divinis nominibits; Expositiones primoe et secundce; In Boethii libros de hebdomadibus; and Proeclare quoestiones super librum Boethii de trinitate. A large number of opuscitla also belonged to this group. Of philosophical writings there are cataloged thirteen commentaries on Aristotle, besides numerous philosophical opuscula of which fourteen are classed as genuine. SUMMA PART I: GOD. The greatest work of Thomas was the Summa and it is the fullest presentation of his views. He worked on it from the time of Clement IV. (after 1265) until the end of his life. When he died he had reached question ninety of part iii., on the subject of penance. What was lacking, was afterward added from the fourth book of his commentary on the "Sentences" of Peter Lombard as a supplementum, which is not found in manuscripts of the thirteenth and fourteenth centuries. The Summa consists of three parts. Part i. treats of God, who is the " first cause, himself uncaused " (primum movens immobile) and as such existent only in act (actu), that is pure actuality without potentiality and, therefore, without corporeality. His essence is actus purus et perfectus. This follows from the fivefold proof for the existence of God; namely, there must be a first mover, unmoved, a first cause in the chain of causes, an absolutely necessary being, an absolutely perfect being, and a rational designer. In this connection the thoughts of the unity, infinity, unchangeableness, and goodness of the highest being are deduced. The spiritual being of God is further defined as thinking and willing. His knowledge is absolutely perfect since he knows himself and all things as appointed by him. Since every knowing being strives after the thing known as end, will is implied in knowing. Inasmuch as God knows himself as the perfect good, he wills himself as end. But in that everything is willed by God, everything is brought by the divine will to himself in the relation of means to end. Therein God wills good to every being which exists, that is he loves it; and, therefore, love is the fundamental relation of God to the world. If the divine love be thought of simply as act of will, it exists for every creature in like measure: but if the good assured by love to the individual be thought of, it exists for different beings in various degrees. In so far as the loving God gives to every being what it needs in relation practical reason," affording the idea of the moral law of nature, so important in medieval ethics. SUMMA PART II.: ETHICS. The first part of the Summa is summed up in the thought that God governs the world as the universal first cause. God sways the intellect in that he gives the power to know aid impresses the species intelligibiles on the mind, and he ways the will in that he holds the good before it as aim, and creates the virtus volendi. To will is nothing else than a certain inclination toward the object of the volition which is the universal good. God works all in all, but so that things also themselves exert their proper efficiency. Here the Areopagitic ideas of the graduated effects of created things play their part in Thomas's thought. The second part of the Summa (two parts, prima secundae and secundae, secunda) follows this complex of ideas. Its theme is man's striving after the highest end, which is the blessedness of the visio beata. Here Thomas develops his system of ethics, which has its root in Aristotle. In a chain of acts of will man strives for the highest end. They are free acts in so far as man has in himself the knowledge of their end and therein the principle of action. In that the will wills the end, it wills also the appropriate means, chooses freely and completes the consensus. THE SUMMA PART III: CHRIST. The way which leads to God is Christ: and Christ is the theme of part iii. It can not be asserted that the incarnation was absolutely necessary, "since God in his omnipotent power could have repaired human nature in many other ways": but it was the most suitable way both for the purpose of instruction and of satisfaction. The Unio between the Logos and the human nature is a " relation " between the divine and the human nature which comes about by both natures being brought together in the one person of the Logos. An incarnation can be spoken of only in the sense that the human nature began to be in the eternal hypostasis of the divine nature. So Christ is unum since his human nature lacks the hypostasis. The person of the Logos, accordingly, has assumed the impersonal human nature, and in such way that the assumption of the soul became the means for the assumption of the body. This union with the human soul is the gratia unionis which leads to the impartation of the gratia habitualis from the Logos to the human nature. Thereby all human potentialities are made perfect in Jesus. Besides the perfections given by the vision of God, which Jesus enjoyed from the beginning, he receives all others by the gratia habitualis. In so far, however, as it is the limited human nature which receives these perfections, they are finite.
