According to the Christian doctrine of the Incarnation, the Son of God is truly but only contingently a human being. But is it also the case that Christ’s individual human nature is only contingently united to a divine person? The affirmative answer to this question, explicitly espoused by Duns Scotus and William of Ockham, turns out to be philosophically untenable, while the negative answer, which is arguably implicit in St. Thomas Aquinas, explication of the Incarnation, has some surprising and significant metaphysical consequences.

What is it for there to be a God, and what reason is there for supposing him to conform to the claims of Christian doctrine? In this pivotal volume of his tetralogy, Richard Swinburne builds a rigorous metaphysical system for describing the world, and applies this to assessing the worth of the Christian tenets of the Trinity and the Incarnation. Part I is dedicated to analyzing the categories needed to address accounts of the divine nature--substance, cause, time, and necessity. Part II begins by setting out, in terms of these categories, the fundamental doctrine of Western religions--that there is a God. After pointing out some of the different ways in which this doctrine can be developed, Swinburne spells out the simplest possible account of divine nature. He then goes on to clarify the implications of this account for the specifically Christian doctrines of the Trinity (that God is "three persons in one substance") and of the Incarnation (that God became incarnate in Jesus Christ). Swinburne finds that there are good reasons to believe the Christian additions to the core Western idea of God. The Christian God builds upon Swinburne's acclaimed previous work to form a self-contained text which will no doubt become a classic in the philosophy of religion.

Thomas Aquinas is often thought to present a compositionalist model of the incarnation, according to which Christ is a composite of a divine nature and a human nature, understood as concrete particulars. But he sometimes seems to hedge away from this model when insisting on the unity of Christ. I argue that if we interpret some of his texts on the assumption of straightforward compositionalism, we can construct a defence of Christ’s unity within that context. This defence involves the claim that the divine unity is so great, and the relation between Christ’s two natures so unusual, that the divine unity can be transferred to the composite Christ as a borrowed property.

In this paper, we examine Abelard’s model of the incarnation and place it within the wider context of his views in metaphysics and logic. In particular, we consider whether Abelard has the resources to solve the major difficulties faced by the so-called “compositional models” of the incarnation, such as his own. These difficulties include: the requirement to account for Christ’s unity as a single person, despite being composed of two concrete particulars; the requirement to allow that Christ is identical with the pre-existent Son, despite the fact that the pre-existent Son is a (proper) part of the incarnate Christ; and finally the requirement to avoid Nestorianism, i.e., the position that Christ’s proper parts are persons in their own right. We argue that Abelard does have adequate solutions to these problems. In particular, we show that his theories of relations and predication can be put to use in defence of a compositional account of the incarnation.

Many skeptics throughout the centuries have accused the New Testament characterization of the incarnation as being incoherent. The reason is that it appears impossible that any person can exemplify human properties such as ignorance, fatigability, and spatial limitation, as the New Testament testifies of Jesus, while possessing divine properties such as omniscience, omnipotence, and omnipresence at the same time. This paper proposes a possible model which asserts that at the incarnation, the Logo's mind was divided into conscious and preconscious, and the divine properties were transferred from the conscious into the preconscious, which became part A of Jesus' preconscious. Simultaneously, the conscious acquired newly created human properties, while a human preconscious which would become part B of Jesus' preconscious and a human body were also created. It is demonstrated that this model does not suffer from the problems that beset other models such as Apollinarianism, two-consciousness Christology, and ontological Kenoticism, and that based on this model the full attributes of divinity and humanity of Jesus as testified by the Scriptures could have simultaneously coexisted in one person without contradiction.

This book offers original essays by leading philosophers of religion representing these new approaches to theological problems such as incarnation.

I suggest that Tim Bayne's use of the term ‘inclusion’ to describe the model of the Incarnation found in Morris and Swinburne may have misled him. The experiences of the Word do not include those of Jesus in the way that mine include my experiences as a teenager; but He is aware, in the case of Jesus, that ‘these experiences are mine’, which is not true of His awareness of the experiences of other people. Again, Bayne rejects the idea that what differentiates the experiences of Jesus from those of the Word is that they differ in kind, on the grounds that they are integrated so as to be co-conscious in the divine consciousness; but this is only true if we think in terms of ‘inclusion’. Nor are any false beliefs held by Jesus part of the beliefs of the Word. Furthermore (although this is not related to ‘inclusion’) while a single soul may be sufficient to unite experiences, it need not be necessary; some other factor may (and I think does) unite the human and divine experiences of Christ.

I make three points in response to Richard Sturch's comments on my paper: I defend my interpretation of the Morris–Swinburne (M–S) account of the Incarnation; I argue that the M–S model appears to undercut the view that the unity of consciousness can be explained in terms of the self; and third, I argue that M–S model seems to entail that God has false beliefs.
