Summa Theologica Part I (Prima Pars) Thomas Aquinas - The Summa Theologiae (Latin: Compendium of Theology or Theological Compendium; also subsequently called the Summa Theologica or simply the Summa, written 1265-1274) is the best-known work of Thomas Aquinas (c.1225-1274), and although unfinished, "one of the classics of the history of philosophy and one of the most influential works of Western literature." It is intended as a manual for beginners in theology and a compendium of all of the main theological teachings of the Church. It presents the reasoning for almost all points of Christian theology in the West. The Summa's topics follow a cycle: the existence of God; Creation, Man; Man's purpose; Christ; the Sacraments; and back to God. (courtesy of wikipedia.com). This is part 1, 'Prima Pars'. Aquinas's greatest work 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 90 of Part III (on the subject of penance). What was lacking was added afterwards 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 was translated into Greek (apparently by Maximus Planudes around 1327), Armenian, many European languages, and Chinese. It 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.

No collection of philosophy or theology is complete without this classic work of Thomas Aquinas. Designed for study, this edition makes the Summa Theologiae accessible to everyone.

"The Summa Theologica is the best-known work of Italian philosopher, scholar, and Dominican friar SAINT THOMAS AQUINAS (1225 1274), widely considered the Catholic Church s greatest theologian. Famously consulted (immediately after the Bible) on religious questions at the Council of Trent, Aquinas s masterpiece has been considered a summary of official Church philosophy ever since. Aquinas considers approximately 10,000 questions on Church doctrine covering the roles and nature of God, man, and Jesus, then lays out objections to Church teachings and systematically confronts each, using Biblical verses, theologians, and philosophers to bolster his arguments. In Volume I, Aquinas addresses: the existence and perfection of God the justice and mercy of God predestination the cause of evil the union of body and soul free will and fate and much more. This massive work of scholarship, spanning five volumes, addresses just about every possible query or argument that any believer or atheist could have, and remains essential, more than seven hundred years after it was written, for clergy, religious historians, and serious students of Catholic thought."

This is the extended and annotated edition including * an extensive biographical annotation about the author and his life The Summa Theologiæ (Latin: Compendium of Theology or Theological Compendium; also subsequently called the Summa Theologica or simply the Summa, written 1265–1274) is the best-known work of Thomas Aquinas (c.1225–1274), and although unfinished, "one of the classics of the history of philosophy and one of the most influential works of Western literature." It is intended as a manual for beginners in theology and a compendium of all of the main theological teachings of the Church.

In a chain of acts of will, man strives for the highest end. They are free acts, insofar 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. Whether the act be good or evil depends on the end. The "human reason" pronounces judgment concerning the character of the end; it is, therefore, the law for action. Human acts, however, are meritorious insofar as they promote the purpose of God and his honor. By repeating a good action, man acquires a moral habit or a quality which enables him to do the good gladly and easily. This is true, however, only of the intellectual and moral virtues (which Aquinas treats after the manner of Aristotle); the theological virtues are imparted by God to man as a "disposition", from which the acts here proceed; while they strengthen, they do not form it. The "disposition" of evil is the opposite alternative. An act becomes evil through deviation from the reason, and from divine moral law. Therefore, sin involves two factors: its substance (or matter) is lust; in form, however, it is deviation from the divine law.
