The Summa Theologica was the best-known work created by St. Thomas Aquinas. It was never completed, yet it is considered a classic in the history of philosophy. Presents the reasoning of Christian theology in the West and the theological teachings of the Catholic Church. Which was divided into three categories.

However, reprobation is instituted, in which anyone is capable of sinning; this is why we have “saving grace”. Nothing in this world is random or free. Since God only has the ability to think and will, this helps establish the relationships of beings in the Trinity. It must be considered real since with God there are no accidents but substance. “The relationship actually existing in God is the same essence according to the thing. “Man is opposed to God; made up of a soul and a body. As an intellectual soul, it brings passive and active. It is made of an immaterial substance, it is not found in just one and is the same in all men. Since certain abilities are already installed in the mind, St. Thomas believed that a form of consciousness, "Synderesis", was innate in people. The Summa, Part 2, part 2 is divided into parts, the first consisting of 114 questions and the second part of 189. Points made in part 2 include: Unbelief is the worst sin. The greatest happiness, the ultimate good, consists in the beatific vision. Collecting interest on loans and selling something for more or less than its value is illegal and prohibited. Accentuative life is more important than active life. The Summa, Part 3, part 3 consists of 90 questions, covering a wide variety of issues related to Christ, such as his nature, his life, the resurrection, the sacraments, and penance. St. Thomas teaches that Christ is to be considered redeemer according to his human nature, but in such a way that human nature produces divine effects as an organ of divinity. The effect of the sacraments is to instill justifying grace in men. The sacraments are the instruments through which this operation of Christ's humanity is transmitted to men. Eschatology is the part of theology that deals with what are believed to be the final events. Eternal bliss consists in the vision of God; this vision does not consist of an abstraction or a supernaturally produced mental image, but the divine substance itself is seen, and in such a way that God himself immediately becomes the form of the contemplating intellect. Summa Theologica in short: This order is cyclical. We begin with God and his existence in question 2. The entire first part of the Summa deals with God and his creation, which reaches its culmination in man. The First Part, therefore, concludes with the treatise on man. The second part of the Summa deals with man's purpose (the meaning of life), which is happiness. Please note: this is just an example. Get a custom paper from our expert writers now.

Since no man alone can truly live a perfect ethical life (and thus reach God), it was necessary for a perfect man to bridge the gap between God and man. Thus God became man. The third part of the Summa therefore deals with the life of Christ. To follow the path prescribed by this perfect man, to live with the grace of God.
