The Summa Theologica of Thomas

The Summa Theologiae was written between 1265–1274 and is also known as the Summa Theologica. It is the best-known work of Thomas Aquinas (1225–1274). Although unfinished, the Summa is "one of the classics of the history of philosophy and o
ne of the most influential works of Western literature." It was intended as a guide for theology students, seminarians and the educated laity. It is a compendium of all of the major theological teachings of the Catholic Church. It presents the reasoning for almost all points of Christian theology in the West. The Summa's topics follow a cycle: God; Creation, Man; Man's purpose; Christ; the Sacraments; and back to God.

Aquinas cites a range of Christian, Muslim, Hebrew, and Pagan sources including but not limited to Christian Sacred Scripture, Aristotle, Augustine of Hippo, Avicenna, Averroes, Al-Ghazali, Boethius, John of Damascus, Paul the Apostle, Dionysius the Areopagite, Maimonides, Anselm, Plato, Cicero, and Eriugena.

Saint Thomas Aquinas himself was an Italian Dominican friar, Catholic priest, and he was appointed a Doctor of the Church. He is venerated as a saint in the Roman Catholic Church and he is considered one of the Catholic Church's greatest theologians and philosophers.

This app form of his work is cross-linked to itself and to the World English Version of the Bible. It also includes a text-to-speech option.
