The Summa Theologica, by Thomas Aquinas, is a fundamental text in Catholic doctrine, a compendium of theology that has been studied and debated since its first publication in the 13th century. Furthermore, it has been widely regarded as one of the classics of Western philosophy, not least because, perhaps for the first time in such a systematic manner, it set out to consider the views of non-Christian figures such as Aristotle, Boethius, Muslim writers including Averroes (Ibn Rushd) and Avicenna (Ibn Sina) and the Sephardic Jewish scholar Maimonides.

Two years before he died, St. Thomas Aquinas, probably the greatest teacher the Church has ever known, was asked by his assistant Brother Reginald to write a simple summary of the faith of the Catholic Church for those who lacked the time or the stamina to tackle his massive Summa Theologica. In response, the great saint quickly set down in language that non-scholars can understand his peerless insights into the major topics of theology: the Trinity, Divine Providence, the Incarnation of Christ, the Last Judgment, and much more.

Reasonable, concise, witty, and wise, Peter Kreeft and Ronald K. Tacelli have written an informative and valuable guidebook for anyone looking for answers to questions of faith and reason. Topics include: faith and reason, the existence of God, God's nature, how we know God, creation and evolution, providence and free will, miracles, and more.

An enthusiastic admirer of the philosophy of Thomas Aquinas, professor and philosopher Peter Kreeft details the rational thought and precise literary talent that established Aquinas as the foremost thinker of his time - and as the most important philosopher for the almost 200 years between Aristotle and Descartes.

The Summa Theologica (Summary of Theology) was written in the 13th century by St. Thomas Aquinas (1225 - 1274). It is a massive compendium of all the main theological doctrines of the Catholic Church, and it was intended to be a guide for theology students.
