Abstract

In lieu of an abstract, here is a brief excerpt of the content:The Christ Who Meets Us in the Sacraments:The Influence of St. Ambrose on the tertia pars of St. Thomas's Summa theologiaeDamian Day O.P.IntroductionThe recent increased interest in St. Thomas Aquinas and the Fathers of the Church has produced a number of excellent studies of the Angelic Doctor's understanding of the authority of the Fathers and his use of them.1 In this article, I hope to contribute to the ongoing study of Aquinas and the Fathers by examining how Thomas employs St. Ambrose in the tertia pars of his Summa theologiae [ST]. Thomas's use of Ambrose has received little detailed [End Page 103] attention. One of Leo Elders's last contributions to the study of Aquinas and the Fathers provided an overview of Ambrose's presence in Thomas's writings.2 I hope to expand upon Elders's work of cataloging and describing Thomas's numerous citations of Ambrose—Thomas names Ambrose over eleven hundred times in his writings3—by making a particular argument about Thomas's Christological and sacramental use of Ambrose. While Elders gives an excellent summary of where Ambrose appears in Thomas's corpus, he does not connect Thomas's use of Ambrose in his treatises on Christ and the Eucharist. I argue that Thomas's citations of Ambrose in the tertia pars help him develop an understanding of the Incarnation that supports his sacramental realism, especially emphasizing contact with Christ in the Eucharist.4Much recent reflection on the Eucharist has sought to deemphasize the substantial presence of Christ and emphasize his presence in other ways. Michael C. McGuckian, for example, argues that the Western emphasis on Christ's presence in the Blessed Sacrament has damaged the understanding of participation in the heavenly liturgy and obscured other ways in which Christ is present, such as in the bishop presiding and the proclamation of the word. He claims that "those other presences surpass the presence in the elements in their personal quality, their dynamic force and their effect on our [End Page 104] spirits and are not to be undervalued."5 Looking at Thomas and Ambrose, we will see that Christ's substantial presence in the Eucharist is preeminently personal, dynamic, and efficacious for our spirits. Colman O'Neill's masterful work of sacramental realism, Meeting Christ in the Sacraments, provides an entrée into such a study. The title derives from Ambrose. In his work A Defense of the Prophet David to Theodosius Augustus, Ambrose reflects on Psalm 51. Suddenly, in the middle of confessing his sins, David foresees the cleansing sacrament of baptism. In prophetic wonder, he cries out, "face-to-face you have shown yourself to me, Christ; I have discovered you in your sacraments."6 Even prior to their institution, David prophetically glimpses what the sacraments of the Old Law prefigure. In this vision, David sees "no longer in shadow, nor in figure, nor in type," but meets Christ in his sacraments.7 For Ambrose, the sacraments are real encounters with Christ. As O'Neill puts it, "Christ, who was worshipped from afar, comes near and touches the believer; and at his touch power goes out from him."8 For [End Page 105] Thomas, too, one meets Christ in the sacraments.9 While all the sacraments apply the merits of his Passion,10 the Eucharist is the locus par excellence for meeting Christ, since the whole Christ is there contained.11 The encounter is both personal and powerful.While the language of meeting or encountering Christ in the sacraments may seem to echo modern phenomenological philosophy, Thomas grounds the encounter in a realism of the Incarnation.12 His treatment of the encounter with Christ in the sacraments flows from his treatment of the Incarnation.13 Guy-Thomas Bedouelle summed up O'Neill's approach, which reflects Thomas's, as simply stressing, again and again, "that sacramental realism implies that the Church draws its life from the dynamism of the Incarnation itself."14 I argue that Thomas, in drawing his sacramental realism from the Incarnation, employs Ambrose as a key authority. First, I examine Thomas's knowledge and use of Ambrose's works. Second, I...
