Catholic education stands in need of renewal, for it too has experienced the consequences of the rupture of faith and reason in the modern period. Secularism affects Catholic schools as well as public ones when faith remains confined solely to a religion class or the celebration of the Mass. Our past provides a model of integration: the unity of divine revelations and the liberal arts and a life of wisdom that pursues what is truly highest. Modern people too often settle for less—little comforts and distractions—while the theologians, philosophers, and educators of the past spur us on to stop at nothing less than God's invitation to enter his divine life. This first volume of the Adeodatus Handbook seeks to provide inspiration to return to the central vision of Catholic education: an integrated approach to the liberal artsthat flows from God's initiative toward us and is ordered toward eternal union with him. The essays of this volume unfold the narrative offered in this introduction in more detail. We consider them to be the most essential figures who have established the Catholic approach to education. Two of them, Plato and Aristotle, were pagan authors who formed the philosophical basis of the Catholic approach. The others, flowing from the Incarnation of the Son of God, appropriated the truths of nature contemplated by philosophy and drew them into a sacramental synthesis with the truths of divine revelation. There can be no genuine Christian education that does help the student to contemplate the whole of reality and to live a life of wisdom, rooted in the virtues that perfect human nature while ultimately receptive of the gifts and fruits of the Holy Spirit. The majority of the figures addressed in this volume are canonized saints, pointing us to the priority of holiness in Catholic education. Education serves the ultimate aim of human life: our perfect happiness in the beatific vision. To reach this, we need the support of mentors and friends. This requires the concrete embodiment of Christian community within the home and school. It can also, however, flow from our communion with the great sainted educators of our heritage. We have inherited their legacy, and with their prayers and support, we have been tasked with continuing in our own age. We will not be able to replicate their efforts, but with the grace and inspiration of the Holy Spirit, we can make our contribution in educating the youth, young adults, seminarians, and lay people of the Church of God.
