Scholars have often been quick to acknowledge Thomas Aquinas's distinctive retrieval of Aristotle's Greek philosophical heritage. Often lagging, however, has been a proper appreciation of both his originality and indebtedness in appropriating the great theological insights of the Greek Fathers of the Church. In a similar way to his integration of the Aristotelian philosophical corpus, Aquinas successfully interwove the often newly received and translated Greek patristic sources into a thirteenth-century theological framework, one dominated by the Latin Fathers. His use of the Greek Fathers definitively shaped his exposition of sacra doctrina in the fundamental areas of God and creation, Trinitarian theology, the moral life, and Christ and the Sacraments. For the sake of filling this lacuna and of piquing scholarly interest in Aquinas's relation to the Fathers of the Christian East, the Aquinas Center for Theological Renewal at Ave Maria University and the Thomistic Institute of the Pontifical Faculty of the Immaculate Conception at the Dominican House of Studies co-sponsored an international gathering of scholars that took place at Ave Maria University under the title Thomas Aquinas and the Greek Fathers. Sensitive to the commonalities and the differences between Aquinas and the Greek Fathers, the essays in this volume have sprung from the theme of this conference and offer a harvest of some of the conference's fruits. At long last, scholars have a rich volume of diverse, penetrating essays that both underscore Aquinas's unique standing among the Latin scholastics in relationship to the Greek Fathers and point the way toward avenues of further study.
