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.

A story of spiritual awakening, St. Augustine's Confessions is a fascinating look at the life of an eminent Christian thinker. Widely seen as one of the first Western autobiographies ever written, it chronicles the life and religious struggles of Augustine of Hippo, from his days as a self-confessed sinner to his acceptance of Christianity as an older adult.

The saints, the heroes of the Roman Catholic faith, lived lives of holiness, dedicated to serving God. The saints lived at different times in different places throughout history, but they all shared a love of God that has been documented through the teachings of the Church. Today, the saints serve as examples for all Catholics, showing the believers how to lead a more spiritual life. Catholic devotions are particular customs, rituals and practices of worship or in honour of the saints that are in addition to the liturgy of the Catholic Church.

After the Bible, The Imitation of Christ by Thomas Kempis is the favorite book of Catholics throughout the world and has been the spiritual guide of the saints since it first appeared in 1418. And of the English editions, none can equal this inspiring translation of Bishop Richard Challoner. This book speaks to the soul of every true Christian, reminding him of the fleeting nature of earthly joy as opposed to the eternity of happiness with God.

For over four decades, Fulton Sheen was the face of Catholicism in America and literally received hundreds of thousands of letters from people around the world in search of truth, faith, salvation, and spiritual guidance. In this new reissue of one of Sheen's classic works, the Emmy Award-winning priest takes an intimate look at our sacred journey to God and answers some of life's most profound questions.

The Story of a Soul conveys St. Therese of Lisieux's "Little Way" of spiritual childhood - her "elevator" to Heaven, as she called it. This method was approved by Pope Pius XI as a way for all to grow in holiness through unfailing confidence and childlike delight in God's merciful love. Again and again in this audiobook, St. Therese shows us how her "Little Way" of love and trust comes straight from Sacred Scripture.

The book acts as a guide which explains how Christianity is the best choice for all human beings, not because it's outside of our world and an independent truth, but because it is the answer to our base needs and desires. Only when Christianity is seen as a way of life instead of a belief can the true power of the faith be realized.

In The Interior Castle, Carmelite nun, mystic, and patron saint of Spain Teresa of Ávila uses the metaphor of a giant crystal castle to explain her theory of the soul and the various stages it passes through as it progresses towards God. Beginning in the outer rooms, where demons are fought and vices are purged, the soul must reach the inner chambers, where it will enter betrothal and intimate union with God. Prayer is central to the journey, as the soul is guided by its practice and each phase represents a different category of devotion.

The book recounts the life of the Virgin Mary and the divine plan both for creation and the salvation of souls. According to María de Ágreda, the book was mostly dictated to her by the Virgin Mary herself. The book moves between describing the Trinity, the Virgin Mary's life, and providing spiritual guidance to the author, which also spiritually benefits the listener. The book describes the virtues and how the listener ought to conduct his or her life using the Virgin Mary as a model for holiness.

In The Bible Is a Catholic Book, Jimmy Akin shows how the Bible cannot exist apart from the church. In its origins and its formulation, in the truths it contains, in its careful preservation over the centuries, and in the prayerful study and elucidation of its mysteries, Scripture is inseparable from Catholicism. This is fitting, since both come from God for our salvation. If you're a Catholic who sometimes gets intimidated by the Bible, The Bible Is a Catholic Book will help you better understand and take pride in this gift that God gave the world through the church.

Gilbert Keith Chesterton (1874-1936) was a British writer, philosopher, lay theologian, and literary critic. Chesterton wrote around 80 books, several hundred poems, some 200 short stories, several plays, plus 4,000 essays and newspaper columns. He was a columnist for the Daily News and The Illustrated London News.

In 2007, Joseph Ratzinger published his first book as Pope Benedict XVI in order “to make known the figure and message of Jesus”. Now, the Pope focuses exclusively on the Gospel accounts of Jesus’ life as a child. The root of these stories is the experience of hope found in the birth of Jesus and the affirmations of surrender and service embodied in his parents, Joseph and Mary.

Over the past hundred years, scholars have attacked the historical truth of the Gospels and argued that they were originally anonymous and filled with contradictions. In The Case for Jesus, Brant Pitre taps in to the wells of Christian scripture, history, and tradition to ask and answer a number of different questions, including: If we don't know who wrote the Gospels, how can we trust them? How are the four Gospels different from other Gospels, such as the lost Gospel of "Q" and the Gospel of Thomas?

The 12 virtues we must all acquire to be happy in this world and to save our souls. The 12 Steps to Holiness and Salvation is compiled from the writings of St. Alphonsus Liguori and is considered one of the classic works of spirituality. St. Alphonsus reviews the 12 key virtues: love, hope, faith, love of God, love of neighbor, poverty, chastity, obedience, meekness and humility, mortification, recollection, prayer, and love of the cross.
