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.

As we all know, and as many of our well-established textbooks have argued for decades, the Inquisition was one of the most frightening and bloody chapters in Western history, Pope Pius XII was anti-Semitic and rightfully called "Hitler's Pope", the Dark Ages were a stunting of the progress of knowledge to be redeemed only by the secular spirit of the Enlightenment, and the religious Crusades were an early example of the rapacious Western thirst for riches and power. But what if these long-held beliefs were all wrong?

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.

My title explains itself. But it's misleading. There are more than 40 reasons. Each of my reasons is an independent point, so I have not organized this book by a succession of chapters or headings. After all, most people only remember a few big ideas or separate points after reading or listening to a book. I've never heard anyone say "Oh, that was a good continuous-process-of-logically-ordered-argumentation" but I've often heard people say, "Oh, that was a good point." And back to my main point: "Why are you a Catholic?" is a good question. A good question deserves a good answer.

The Confessions of St. Augustine is one of the most moving diaries ever recorded of a man's journey to the fountain of God's grace. Writing as a sinner, not a saint, Augustine shares his innermost thoughts and conversion experiences, and wrestles with the spiritual questions that have stirred the hearts of the thoughtful since time began.

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.

One of the most influential philosophers and theologians in the history of Western thought, St Thomas Aquinas established the foundations for much of modern philosophy of religion, and is famous for his arguments for the existence of God. In this cogent and multifaceted introduction to the great saint's work, Edward Feser argues that you cannot fully understand Aquinas' philosophy without his theology, and vice-versa. He covers Aquinas' thoughts on the soul, natural law, metaphysics, and more.

The four books of the Summa contra Gentiles were written by Thomas Aquinas between 1259-1265, before the considerably larger and more influential, Summa Theologica. The purpose of each work was different. Whereas the Summa Theologica addressed the faithful, especially theology students, the intention of the Summa Contra Gentiles (Systematic Exposition Against Non-Christians) was to speak to a non-aligned and even hostile audience. To that purpose, Aquinas presented arguments ‘refuting specific beliefs or heresies.'

Saint Augustine's contributions to Christian theology are second to no other post-apostolic author in the whole sweep of church history. Yet along side his doctrinal treatises, Augustine tells a story of his life devoted to Christ as his only satisfaction. The Confessions is at once the autobiographical account of Augustine's life of Christian faith and at the same time a compelling theology of Christian spirituality for everyone.

The Petrine verses (or Biblical passages referring to St. Peter, his role, and the office of the papacy) are perhaps the most controverted passages in the history of Christianity in the last 1, 000 years. This study of St. Peter’s role in the Bible puts to rest any doubts about the true sources for and meaning behind Jesus’s commission to St. Peter (Matthew 16:18), not to mention numerous other passages out of both the Old and New Testaments. Employing language accessible to an average reader, all historically debated passages about St. Peter and the papacy are unpacked so that their ...

The Diary is an amazing narrative that chronicles the experiences of a simple, uneducated Polish nun who received a special call shortly before the outbreak of World War II. Our Lord appeared to her and instructed her to spread the message of his Divine Mercy to all, especially in our current age, which is full of so much distress and worldliness. The message of the Divine Mercy is that God loves us all of us. And He wants us to recognize that his mercy is greater than our sins, so that we will call upon him with trust, receive his mercy, and let it flow through us to others.
