The *Summa Theologiae*, often called the *Summa*, is a massive work of Christian theology. It was written by Thomas Aquinas, a famous scholastic theologian. Aquinas lived from 1225 to 1274. He is known as a Doctor of the Church. The *Summa* serves as a compendium of Catholic teachings. A compendium is a concise collection of detailed information. This work presents the reasoning for almost all points of Western Christian theology. It is considered a classic of Western literature. It also represents the most perfect work of Aquinas's mature years.

The work follows a specific cyclic structure. It begins with the study of God. The cycle then moves to Creation, Man, and the purpose of human life. From there, it discusses Christ and the Sacraments. Finally, the cycle returns to God. This structure helps organize a vast amount of complex information.

Aquinas designed the *Summa* as a pedagogical tool. Pedagogy refers to the method and practice of teaching. He specifically intended it to be a work for beginning students. The book is organized into a strict hierarchy. There are three main parts, known as *Pars*. These parts contain 614 Questions. Each question is subdivided into many Articles. In total, the work contains 3,125 Articles. Questions cover specific topics of discussion. Articles focus on even more specific facets of those topics. For example, one question might be about the existence of God. The articles within it would ask if that existence is self-evident or demonstrable.

The three parts of the *Summa* cover different areas. The First Part (*Prima Pars*) includes 119 Questions and 584 Articles. It covers God, the creation of the world, angels, and human nature. The Second Part is divided into two sub-parts. The first sub-part covers general principles of morality and law. It includes 114 Questions and 619 Articles. The second sub-part covers morality in particular, such as virtues and vices. This section contains 189 Questions and 917 Articles. The Third Part (*Tertia Pars*) focuses on Christ and the sacraments. It includes 90 Questions and 549 Articles. Aquinas did not finish this part before he died. A posthumous supplement was later added to conclude the work. This supplement discusses Christian eschatology, which is the study of "the last things." There are also two small appendices regarding purgatory.

Aquinas used a unique method of exposition for his articles. This method was inspired by the thinker Averroes. Aquinas respectfully called Averroes "the Commentator." Each article follows a standard four-step format. First, the author presents a series of objections. These are arguments against the conclusion that will be stated. Second, a conclusion is extracted from the objections. Third, a counter-statement is provided. This statement usually cites an authority, such as the Bible or Aristotle. This part often begins with the phrase "on the contrary." Fourth, the actual argument is made. This begins with the phrase "I answer that." This section clarifies the issue and provides the main reasoning. Finally, Aquinas provides individual replies to the original objections.

To build his arguments, Aquinas drew from many diverse sources. He relied heavily on the Bible and the Church Fathers. He also aimed to reconcile Aristotelian philosophy with Catholic theology. He referred to Aristotle as "the Philosopher." He also cited the influential thinker Augustine. Aquinas engaged with many non-Christian sources as well. He referenced Islamic scholars like Avicenna and al-Ghazali. He also studied Jewish scholars like Rabbi Moses Maimonides. He even used the writings of Roman jurists like Ulpian. This wide range of sources shows the intellectual depth of the work.

The *Summa* has had a massive impact on history and culture. It was a primary inspiration for Thomistic philosophy. It even deeply influenced the poet Dante Alighieri. Some scholars call Dante's *Divine Comedy* "the Summa in verse." Today, the work remains a major reference for many. It is used in both Western and Eastern Catholic Churches. It is also studied by mainline Protestant denominations like Anglicans, Lutherans, Methodists, and Reformed Christians. It is used by those seeking ordination to the priesthood or diaconate. It also serves as a text for laypersons studying theology at the college level.
