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.

St. Thomas Aquinas' Summa Theologica is the premier work of Catholic theology, studied at all major Catholic universities and seminaries, as well as by theologians and philosophers of religion of all denominations. Of St. Thomas' many works, this masterpiece presents a systematic and organic treatment of several thousand important theological questions, ranging from God, the Trinity, and the nature of Christ, to the nature and psychology of the human person and the nature and mission of the Church. St. Thomas considers creation in its natural light, as well as under the operations of grace, including discussions of morality, redemption, the sacraments, and the operation of divine providence. The scope of topics is enormous, and these few hardly do justice to the contents. The format of this work is arranged into individual articles for easy reading of St. Thomas' answers to individual questions, but there is a continuity to the way questions are raised and answered that makes the work a unified whole -- not simply a theological manual or encyclopedia, but also a profound read from cover to cover. A leading biographer of Thomas (O'Meara) has called the Summa 'a cathedral of thought, ' which is perhaps the best description for such a short space here. I heartily recommend this work and this particular edition of the Summa in English

It is the greatest achievement of Saint Thomas Aquinas and one of the most influential works of Western literature and Philosophy. His influence on Western thought is considerable, and much of modern Philosophy was conceived as a reaction against, or as an agreement with, his ideas, particularly in the areas of Ethics, Natural Law, Metaphysics, and Political Theory. It is intended as a manual for beginners in Theology and a Compendium of all of the main Theological teachings of the Roman Catholic Church. It presents the reasoning for almost all points of Christian Theology in the West. The book is famous, among other things, for its five arguments for the existence of God, the Quinque viae. The Summa Theologica's topics follow a cycle: The Existence of God; Creation, Man; Man's Purpose; Christ; The Sacraments; and back to God. The first part is on God. In it, he gives five proofs for God’s existence as well as an explication of His attributes. He argues for the actuality and incorporeality of God as the unmoved mover and describes how God moves through His thinking and willing. The second part is on Ethics. Thomas argues for a variation of the Aristotelian Virtue Ethics. However, unlike Aristotle, he argues for a connection between the virtuous man and God by explaining how the virtuous act is one towards the blessedness of the Beatific Vision (beata visio). The last part of the Summa is on Christ and was unfinished when Thomas died. In it, he shows how Christ not only offers salvation, but represents and protects humanity on Earth and in Heaven. This part also briefly discusses the sacraments and eschatology. The Summa remains the most influential of Thomas’s works. Saint Thomas Aquinas was a Dominican Priest, born near Aquino, Sicily in 1225. He was an immensely influential Philosopher and Theologian in the tradition of Scholasticism, known as Doctor Angelicus. He died in 1274. As one of the 33 Doctors of the Church, he is considered the Church's greatest Theologian and Philosopher. Thomas is held in the Catholic Church to be the model teacher for those studying for the priesthood. He was canonized in 1323. PUBLISHER: CATHOLIC WAY PUBLISHING

"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."
