The startling assertion that "the laity must be apostolic" requires unpacking as the Church becomes more and more confined in modern society. But, as Fr. Francis Wendell shows in this short book, there is a transformative "philosophy of presence that can be exercised only by lay people since they are present in and are of the world." In this short work, Fr. Wendell shows how: - the laity must avoid a purely external living of Christianity - how there is no one-size-fits-all program for the la...

The Thomistic Response to the Nouvelle Théologie: Concerning the Truth of Dogma and the Nature of Theology retrieves the most important and largely forgotten exchanges in the mid-20th-century debate surrounding ressourcement thinkers. It makes available new translations of works by the leading Thomists in the exchange: Dominican Fathers Reginald Garrigou-Lagrange, Michel Labourdette, Marie-Joseph Nicolas, and Raymond Bruckberger. In addition to a lengthy historical and theological introductio...

To the medieval thinker, man was the center of creation, and all of nature existed purely for his benefit. The shift from the philosophy of the Middle Ages to the modern view of humanity's less central place in the universe ranks as the greatest revolution in the history of Western thought, and this classic in the philosophy of science describes and analyzes how that profound change occurred. A fascinating analysis of the works of Copernicus, Kepler, Galileo, Descartes, Hobbes, Gilbert, Boyle...

J. R. R. Tolkien was a profoundly metaphysical thinker, and one of the most formative influences on his imagination, according to this new study of his works, was the great thirteenth-century theologian, St. Thomas Aquinas. Structured around Tolkien’s Middle-earth creation myth, the Ainulindale, The Flame Imperishable follows the thought of Aquinas as a guide in laying bare the deeper foundations of many of the more familiar themes from Tolkien’s legendarium, including such notions as sub-cre...

Preliminaries to a Spirituality of Work In what way can human beings attain that Harmony whereby they become mediators between Heaven and Earth? In the mysterious language of symbols we can rediscover the sense of vocation that reflects Divine Activity. For God is, in reality, the sole Artisan. All the traditional crafts strive to imitate within their limitations the work of God, Who unceasingly creates and maintains the world. And in the end it is this that constitutes the sole foundation of...

Examination of Conscience of Moral Theology Many of us think of moral theology as lists of what is allowed and what is forbidden. Fr. Wojciech Giertych, O.P., longtime Theologian of the Papal Household, proposes a far more beautiful approach. Drawing on St. Thomas Aquinas and St. John Paul II, he presents Christian morality as God's fatherly plan of love: an invitation to use our gifts and opportunities with maturity and charity, and so to grow in union with Him. A clear and uplifting book fo...

In Common Sense for a World of Common Nonsense, Dr. Donald DeMarco examines modern moral confusion through sharp, philosophical essays that contrast virtue with ideology. Divided into “Common Nonsense” and “Common Sense,” the book critiques gender ideology, abortion, relativism, and other cultural errors while affirming tradition, rationality, and Christian moral wisdom. Drawing on Scripture, Church teaching, and the insights of classical thinkers, DeMarco argues for the indispensable role of...

Donald DeMarco's Without God Nothing Makes Sense argues that removing God from public discourse leads to societal confusion and moral decay. DeMarco critiques ideologies like radical feminism, atheism, and the pro-abortion lobby, identifying their rejection of divine truths as sources of division and intellectual blindness. He emphasizes the importance of virtues such as lightheartedness, kindheartedness, and warmheartedness, which align with faith in God and serve as antidotes to societal fr...

To help celebrate the fourth centenary of the birth of St. John of the Cross in 1542, Edith Stein received the task of preparing a study of his writings. She uses her skill as a philosopher to enter into an illuminating reflection on the difference between the two symbols of cross and night. Pointing out how entering the night is synonymous with carrying the cross, she provides a condensed presentation of John's thought on the active and passive nights, as discussed in The Ascent of Mount Car...

Following his acclaimed The Word Has Been Abroad: A Guide Through Balthasar’s Aesthetics, No Bloodless Myth by Aidan Nichols offers a lucid and accessible guide to the five-volume Theo-Drama of Hans Urs von Balthasar, one of the most ambitious theological projects of the twentieth century. In Theo-Drama, Balthasar presents the Christian revelation as a divine drama in which God and humanity are real actors, not abstract principles. Nichols carefully summarizes and interprets this vast work, s...

“It is true that there can be no more important half-hour in the forty-eight half hours which make up a complete calendar date. But you can go further than this and say that the time of Mass is the most important in the century, in history, in life. It is Calvary all over again, and nothing more important could happen in this world than the redemption of man by the crucifixion.” At the heart of every Catholic’s life is the Mass. As such, it is a form of prayer that demands awareness, reverenc...

The biblical “primal history” of Genesis 1–11—from the Fall to the Tower of Babel—portrays a pattern of human evil that resonates strongly with the modern world. Yet the doctrine of original sin has become problematic for many today, shaped by a modern outlook that sharply separates nature and freedom. In this final work, Raymund Schwager offers an interdisciplinary exploration that seeks to bridge this divide. Drawing from evolutionary theory, contemporary philosophy, theology, and developme...

Why do some religious believers slaughter those who refuse to convert to their faith, refuse scientific evidence for an ancient universe, or hold God to be an utterly arbitrary being? Why do some scientists believe that universes pop into existence from nothing, that aliens seeded life on earth, or that fish turn into reptiles by chance processes? The answer, for both, is the same: the abandonment of realism, the human way for knowing reality. In The Realist Guide to Religion and Science, Fr ...

Readers are guided through writings by Aristotle th...

The ancient philosophy, in its original Orphico-Pythagorean and Platonic form, is not simply a way of life in accordance with the divine or human intellect (nous), but also the way of alchemical transformation and mystical illumination achieved through initiatic 'death' and subsequent restoration at the level of divine light. To use another mythical image, philosophy restores the soul's wings and leads the purified lover of wisdom to Heaven. As a means of spiritual reintegration and unificati...

Christian revelation has provided a goldmine of resources to tap into to develop our understanding. But in expanding our minds, it has also led many to ponder many curiosities and difficulties which have solutions that lead us closer to God. The sermon is one way to provide insight into these matters in a way that combines intellectual theory with heartfelt need in our daily lives.The tongue-in-cheek title of the book proposes that we often wonder much more about the world than we are comfort...

This book presents the chief insights concerning the mystery of atonement in the works of four theological guides: John Paul II, Joseph Ratzinger/Benedict XVI, Hans Urs von Balthasar, and Norbert Hoffmann.The author argues for the central importance and perennial value of a theology of atonement, even as she explains the modern aversion to it. The book's central aim is to deepen our understanding of the biblical claim that God shows himself to be love precisely by sending his Son as atonement...

Spanning nearly 500 miles across the Rocky Mountains, the Colorado Trail is an epic, arduous route through some of America's most breathtaking natural grandeur. In the summer of 2022, Fr. John Nepil, priest-theologian and mountaineer, set out to traverse the entire trail as a "thru-hike" with a trio of companions, accompanied along the way by an eclectic rotating cast of priests and young people. This memoir, which is simultaneously a theological reflection on life, Christianity, and the moun...

The greatest teacher of philosophy in all of history was Socrates, according to philosopher Peter Kreeft. In 2,400 years, no one has topped him or his Socratic method, teaching not by monologue, but by dialogue; not by lecturing, but by logical questioning. Yet of the hundreds of textbooks for beginning philosophers today, none uses his method.Kreeft has imagined Socrates University: a log, with Socrates at one end and a typical intelligent modern student beginner at the other, conversing abo...

An exemplary summary of the state of Catholic theology—and a clear indication of its future—this work offers a historical and methodological introduction to Catholic theology that focuses not on doctrinal content alone, but on the form in which that content is received, ordered, and articulated. Rather than surveying individual teachings, Fr. Aidan Nichols, O.P., examines the sources, principles, and intellectual habits that shape Catholic theology as a living discipline. He explores how Scri...

"Behold, this child is appointed for the fall and rising of many in Israel, and for a sign of contradiction." For the 1976 Lenten retreat to St. Paul VI and the Roman curia, Karol Wojtyla set this prophecy of Simeon to the Holy Family at the heart of his preaching. Over the course of twenty-two meditations, Wojtyla examines and tests the apparent contradictions in the words and deeds of Jesus Christ-all of which are occasions for profound encounters with God himself. Indeed, the "words a sign...

The Mystery of Christ Our Savior: The Person, Life, and Redemption of Jesus According to St. Thomas Aquinas St. Thomas Aquinas gave the Church one of her richest visions of Jesus Christ, yet many Catholics find the Summa Theologiae daunting. Fr. Mauro Gagliardi opens up Aquinas's teaching on Christ and our salvation in a form that is faithful, readable, and spiritually fruitful. Drawing directly from the Summa, Fr. Gagliardi presents Christ not as an abstract subject of debate but as the Word...

St. Thomas Aquinas did not reach his towering wisdom by standing still. His thought was forged on the road, in castles and cloisters, universities and cities, mountains and monasteries. In The Way of Aquinas: A Travelogue for Human Beings, philosopher Chad Engelland retraces the journeys that shaped the Angelic Doctor, from his noble birth to his final days. Along the way he makes the inner logic of Thomas's philosophy and theology vivid and approachable, showing how it speaks to our own jour...

Divine Revelation: The Bible According to Vatican II is Henri de Lubac's commentary on Dei Verbum, the Second Vatican Council's Dogmatic Constitution on Divine Revelation. More than a line-by-line study, it is a moving treatise on what revelation is and what it means to believe. Steeped in Scripture and the Church Fathers, de Lubac returns again and again to the heart of the matter: in revelation God does not simply hand us information, He gives Himself, and faith is our grateful acceptance o...

One day, philosopher Peter Kreeft reads an open letter published by a friend, Nat Whilk. He's Catholic, but he sees the Church as unsteady, outdated, obsessive. As a challenge to the "True Believers", Nat pens a twenty-point manifesto for "cafeteria Catholics", who pass up certain Church teachings and scoop up others like a diner in a buffet line."I find in [Catholicism] both much to accept and even love and also much to refuse and even despise", he asserts. "If you insist on tying God to the...

The Host of Gethsemane is a deeply researched and spiritually rich exploration of the profound significance of the Garden of Gethsemane. More than a work of study, it is a labor of love—a defense of Jesus of Gethsemane in every sense of the word. Despite the centrality of Christ’s Agony in the Garden to the Paschal Mystery, remarkably few books have been dedicated entirely to this sacred moment. The Host of Gethsemane remedies that neglect, restoring Gethsemane to its rightful place as a sanc...

Metaphysics and Hermeneutics of the Image Thomas Pfau's study of images and visual experience is a tour de force linking Platonic metaphysics to modern phenomenology and probing literary, philosophical, and theological accounts of visual experience from Plato to Rilke. Incomprehensible Certainty presents a sustained reflection on the nature of images and the phenomenology of visual experience. Taking the "image" (eikōn) as the essential medium of art and literature and as foundational for the...

The Philosophy of Existence, among the first translations into English of the Catholic existentialist Gabriel Marcel, is composed of four distinct essays--"On the Ontological Mystery"; "Existence and Human Freedom"; "Testimony and Existentialism"; and "An Essay in Biography." Together, the essays articulate the integral elements, constitutive terminology, and characteristic anthropology of Marcel's philosophy of existence, and describe its marked differences with the atheist existentialism of...

The author synthesizes the best a...

A profound exploration of human ensoulment and personhood at the moment of conception, this bioethical and theological study shows how the mystery of Christ’s Incarnation—beginning as a one-cell zygote—sheds light on the mystery of every human person. Drawing from Scripture, Tradition, Church teaching, science, philosophy, and theology, The Zygote of Christ & The Mystery of Man defends human conception and embryonic life as an icon of both God’s creative act and the Incarnation itself. It...

Kenneth Francis reveals the hidden grammar in classic popular songs theologically marinated in existential narratives, featuring idolatry, sin, love, pathos and meaning. And what better religion to focus on than Christianity for such themes, from the soul-music classics of the 1960/70s, to the Top 100 Billboard hits of the same eras. Welcome to the world of classic songs permeated with Christian themes.

Science of the Day versus Everlasting Science examines the contrast between the classical understanding of science, grounded in certainty through causes, and the modern scientific mindset shaped by constant change, novelty, and materialism. Drawing on the Aristotelian tradition, the book presents science as a stable form of knowledge ordered toward truth, rather than an endlessly shifting collection of provisional theories. D. G. Boland critiques the modern tendency to detach science from met...

When the medieval theologian Thomas Aquinas addressed the best arguments against God in his masterwork, the Summa Theologica, he listed only two. The first was the problem of evil: How can God -- who is perfectly good -- exist alongside that which is against Him? His second: Is God really needed to explain the world? In this landmark work, Patrick Flynn presents the best arguments for God while also addressing the strongest objections. This book is destined to become the apologetic gold stand...

Since the beginnings of the Church, much has been written about the Trinity in the Creator. In this accessible book for ordinary Christians, Peter Kreeft reflects on a different topic: the Trinity in the creation.Because, as G. K. Chesterton put it, in creating us, God "broke His own law, and made a graven image of Himself", it comes as no surprise that we find a Trinitarian structure embedded in our lives--not to mention the universe itself. While the fact that so many things come in threes ...

The Summa Theologiae is a work of astounding breadth and scope: five folio vol-umes of closely packed print, and more closely packed thought; incredibly, it was a work intended, not for the learned and wise, but for beginners. Walter Farrell, O.P., fully honors that intention with his four Companion volumes to the Summa, which together offer an easy guidebook to St. Thomas's greatest work. These are not simply more books about St. Thomas or about the Summa; rather, they are a distillation of ...

Neither a theological study of our Redemption nor a devotional commentary of the Cross and Resurrection, but rather an introduction to the liturgical celebration of Holy Week and Easter, this book is written in the double conviction that the depth of meaning of the Paschal Mystery is seriously weakened if it is not given its full liturgical and sacramental expression, and that the Holy Week liturgy demands from all who participate in it a more profound awareness of its biblical background and...

This concise and insightful study examines Aidan Nichols’s vision for an Anglican Uniate Church, a community united with Rome yet not absorbed into it. In 1993, Nichols argued that full corporate reunion of the entire Anglican Communion was unrealistic, given the Protestant and Liberal elements within Anglican history. Instead, he proposed the reconciliation of a smaller body that was sufficiently Catholic in identity while retaining authentically Anglican patrimony. His prediction proved pro...

This work introduces the fundamentals of logical thinking by examining how the human mind forms ideas, evaluates evidence, and arrives at sound conclusions. William Walker Atkinson explains the major modes of reasoning—deductive, inductive, and hypothetical—using clear language and accessible examples designed for the general reader. Beginning with the formation of ideas and concepts, the book distinguishes between concepts and mere terms, showing how memory supplies names while reasoning det...

Hans Urs von Balthasar is widely regarded as one of the greatest Catholic theologians of the twentieth century. Few writers have so powerfully revealed the spiritual grandeur of divine revelation or shown how the Church’s art and historic liturgies bear witness to its beauty and depth. Yet for many students and nonspecialist readers, Balthasar’s vast body of work can appear daunting and inaccessible. This volume offers an ideal introduction to Balthasar’s theology. Written by Aidan Nichols, i...

The Word Has Been Abroad serves as a clear and reliable guide to the theological aesthetics of Hans Urs von Balthasar, one of the most original and demanding theologians of the twentieth century. In this volume, Aidan Nichols introduces readers to Balthasar’s conviction that beauty is not an optional ornament of theology but an essential dimension of divine revelation. Nichols carefully explains the central themes of Balthasar’s theological aesthetics, showing how the “form” (Gestalt) of Chri...
