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.

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.

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.

Canonized on June 16, 2002, Padre Pio of Pietrelcina (1887-1968) was a Capuchin monk and mystic whose life was marked with miracles and wonders, but who said that his only desire was “to be a poor friar who prays.” In this intimate biography, you will see the results of this humble Capuchin's prayers and discover for yourself the source of his great hope. This updated edition contains five new chapters covering the years between beatification and canonization, St. Pio’s continued work in people’s lives, and the devotion of St. John Paul II to this extraordinary saint.

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.

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.

How can you believe all this stuff? This is the number one question Catholics get asked - and, sometimes, we ask ourselves. Why We're Catholic assembles the clearest, friendliest, most helpful answers that Trent learned to give to people. Beginning with how we can know reality and ending with our hope of eternal life, it's the perfect way to help skeptics and seekers (or Catholics who want to firm up their faith) understand the evidence that bolsters our belief - and brings us joy.

The City of God is one of the most important works of Christian history and philosophy ever written. The writings of St. Augustine are as intriguing to the casual reader as it is to Christian researchers. St. Augustine's work provides insight into Western thought and the development of Western civilizations. The City of God provides the reader with an artful contrast between earthy cities and those in heaven as a representation of the eternal struggle between good and evil. The City of God was originally penned in the early 5th century as a response to the prevalent belief that Christianity was to blame for the fall of Rome. St. Augustine is known as one of the most influential Fathers of the Catholic Church. Born November 13, 354, Augustine would eventually be recognized as a Saint by the Catholic Church, the Eastern Christian Church, and the Anglican Communion.

This book paraphrases 86 of Pope John Paul II's talks on the theology of the body in easy-to-understand English.

Considered by many to be the greatest single book of Marian spirituality ever written, True Devotion to Mary is St. Louis de Montfort's classic statement on the spiritual way to Jesus Christ though the blessed Virgin Mary. Beloved by countless souls, this book sums up the entire Christian life, revealing a way of holiness that is short, easy, secure, and perfect. In this beautiful and sublimely inspiring book, de Montfort explains the wonderful spiritual effects which true devotion to Mary brings about in a person's life.

Salvation and spiritual perfection should not be sought haphazardly; a strategy is needed to win the battle for our souls. The Spiritual Combat, first published in 1589, provides timeless guidance in spiritual discipline. St. Francis de Sales (1576-1622) read from it himself every day and recommended it to everyone under his direction.

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.

Whether taken as a book of faith or a cultural artifact, the New Testament is among the most significant writings the world has ever known, its web of meaning relied upon by virtually every major writer in the last 2,000 years. Yet the New Testament is not only one of Western civilization’s most believed books, but also one of its most widely disputed, often maligned, and least clearly understood, with a vast number of people unaware of how it was written and transmitted.

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.

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.
