This book is an insightful exploration of Aquinas's views on how Christ could be both divine and human but still only be one person.

The quest for unity and multiplicity is one of the most important concerns in the history of human thought. Since the origins of the history of philosophy up to the present, we can observe more or less unceasing interest in the issue. The same holds of the writings of Thomas Aquinas, to whose conception this work is devoted. Since the problem of unity and multitude is closely linked to many other key metaphysical issues, such as the doctrine of transcendental concepts, the mode of composition of being qua being, as well as substantial and accidental being, or the doctrine of whole and part, we believe that its proper interpretation not only can clarify some partial metaphysical problem, but will also contribute to understanding the metaphysical thought of the Angelic Doctor as a whole.

The period from Thomas Aquinas to Duns Scotus is one of the richest in the history of Christian theology. The Metaphysics of the Incarnation aims to provide a thorough examination of the doctrine in this era, making explicit its philosophical and theological foundations. Medieval theologians believed that there were good reasons for supposing that Christ's human nature was an individual. In the light of this, Part 1 discusses how the various thinkers held that an individual nature could be united to a divine person. Part 2 shows how one divine person could be incarnate without any other. Part 3 deals with questions of Christological predication, and Part 4 shows how an individual nature is to be distinguished from a person. The work begins with a full account of the metaphysics presupposed in the medieval accounts, and concludes with observations relating medieval accounts to modern Christology.

This work presents a historically informed, systematic exposition of the Christology of the first seven Ecumenical Councils of undivided Christendom, from the First Council of Nicaea in 325 AD to the Second Council of Nicaea in 787 AD. Assuming the truth of Conciliar Christology for the sake of argument, Timothy Pawl considers whether there are good philosophical arguments that show a contradiction or incoherence in that doctrine. He presents the definitions of important terms in the debate and a helpful metaphysics for understanding the incarnation. In Defense of Conciliar Christology discusses three types of philosophical objections to Conciliar Christology. Firstly, it highlights the fundamental philosophical problem facing Christology-how can one thing be both God and man, when anything deserving to be called "God" must have certain attributes, and yet it seems that nothing that can aptly be called "man" can have those same attributes? It then considers the argument that if the Second Person of the Holy Trinity were immutable or atemporal, as Conciliar Christology requires, then that Person could not become anything, and thus could not become man. Finally, Pawl addresses the objection that if there is a single Christ then there is a single nature or will in Christ. However, if that conditional is true, then Conciliar Christology is false, since it affirms the antecedent of the conditional to be true, but denies the truth of the consequent. Pawl defends Conciliar Christology against these charges, arguing that all three philosophical objections fail to show Conciliar Christology inconsistent or incoherent.

The Eucharist is at the heart of Christian worship and at the heart of the Eucharist are the curious phrases, 'This is my body' and 'This is my blood'. James M. Arcadi offers a constructive proposal for understanding Christ's presence in the Eucharist that draws on contemporary conceptual resources and is faithful to the history of interpretation. He locates his proposal along a spectrum of Eucharistic theories. Arcadi explores the motif of God's presence related to divine omnipresence and special presence in holy places, which undergirds a biblical-theological proposal concerning Christ's presence. Utilizing recent work in speech-act theory, Arcadi probes the acts of consecration and renaming in their biblical and liturgical contexts. A thorough examination of recent work in Christology leads to an action model of the Incarnation that borrows the notion of enabling externalism from philosophy of mind. These threads undergird a model of Christ's presence in the Eucharist.

This book makes a major contribution to contemporary theological and philosophical debates, bridging scriptural and metaphysical approaches to the triune God. Bridges the gap between scriptural and metaphysical approaches to biblical narratives. Retrieves Aquinas’s understanding of theology as contemplative wisdom. Structured around Aquinas’s treatise on the triune God in his ‘Summa Theologiae’. Argues that intellectual contemplation is part of a broader spiritual journey towards a better understanding of God. Contributes to the current resurgence of Thomistic theology in both Protestant and Catholic circles.
