Get the original essay The Summa, Part 1, God rules the world, and advocated that some will be guaranteed eternal life and others will fail. However, reprobation is instituted, in which everyone is capable of sinning; this is why we have “saving grace”. Nothing in this world is accidental or gratuitous. Since God only has the capacity to think and will, this helps establish the relationships of beings on the trinity. It must be considered real since there are no accidents with God other than substance. “The relation actually existing in God is the same as the essence according to the thing. “Man is opposed to God; composed of a soul and a body. As an intellectual soul, it carries the passive and the active. It is made up of an immaterial substance, and is not found in one person but is the same in all men. Because the mind is already installed with certain capacities, Saint Thomas believed that a form of consciousness “syderesis” was innate in man. 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. God's greatest happiness, the ultimate good, consists of the beatific vision. It is illegal and prohibited to charge interest on loans and to sell something for more or less than its value. The exemplary life is greater than an active life.

Eternal beatitude 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 contemplated, and in such a way that God himself immediately becomes the form of the contemplating intellect. Summa Theologica in brief: This order is cyclical. It begins with God and his existence in question 2. The entire first part of the Summa deals with God and his creation, which reaches its climax in man. The first part therefore ends with the treatise on man.
