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...

In the struggle to find the touchstone between faith and reason, modern psychology is often a very problematic area for Catholics. Why? Because post-Freudian psychology is based on a mistaken idea that moral laws lead to neurosis. It argues that we must be freed from morality in order to become psychologically whole. In this powerful and assuring book, Fr. Brian Mullady examines the nature of a healthy Christian emotional life, and ultimately provides the Catholic answer to the problematic th...

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 ...

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.

It...

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...

The author synthesizes the best a...

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...

"When people stop believing in God, the problem is not that they will believe in nothing, the problem is that they will believe in anything." --C. S. Lewis Business luminary Bob Trussell uses plain language and simple logic to merge scientific theory with philosophy, religion, and the Bible to make an air-tight case for belief in God and all that that can mean for your current life and the life to come.

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.

These are not simply more books about St. Thomas or about the Summa; rather, they are a distillation of ...

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.

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...

The Ascent of the Mind to God stands apart from St. Robert Bellarmine’s apologetical writings as a deeply personal spiritual work. Composed after a retreat in 1614, Bellarmine affectionately called it his “Benjamin,” the child of his old age, and the first of a series of spiritual reflections that have nourished Christians for centuries. Structured around fifteen steps of a spiritual ladder, the book begins with the human person—man as a “microcosm” of creation—inspired by the foundational pr...

From its founding in 1928, the Fellowship of St Alban and St Sergius created an unprecedented bridge between Russian Orthodoxy and the Christian West. Through its journal—first under the Fellowship’s name and later as Sobornost—it became the principal venue where the exiled Russian Orthodox intelligentsia engaged with Anglican theologians of the Catholic party, as well as, on occasion, with other Protestant traditions. In this deeply researched account, Aidan Nichols traces the journal’s evol...

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...

Welcome to the world of classic songs permeated with Christian themes.

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...
