The Trinity

The core of a Trinitarian model is the internal layout of intra-Trinitarian relations. Depending on different metaphysical interpretations of the nature of the relations, various patristic authors have produced different and oftentimes incompatible Trinitarian models, and, consequently, conflicting expositions of the doctrine of the Trinity. In order to elucidate the differences in their Trinitarian theologies, I demonstrate the divergence in their understanding of the divine relations using the contemporary philosophical taxonomy of relations. I analyze the models of Basil of Caesarea, (...) Gregory Nazianzen, and Boethius, and their attempted synthesis by Thomas Aquinas. Each of the patristic Trinitarian models, in spite of being fully orthodox, uses completely different types of relations, which makes them incompatible. One of the results of this incompatibility is the problem of the filioque, which cannot be resolved without addressing the metaphysics of relations. (shrink)

In this essay, I argue that the Incarnation of the Son of God, understood in a traditionally orthodox way, is incompatible with an atemporalist concept of God. First, I explain what I mean by atemporalism, namely the idea that God exists outside time. I also show the main corollaries of that doctrine, most notably that all of God’s life occurs eternally simultaneously. Second, based on New Testament teaching and widely accepted creeds, I spell out philosophically what I mean by the (...) Incarnation. In short, I take it to be the doctrine that the Second Person of the Trinity at some point in time took on a human body as part of a fully human nature. I then proceed to my central argument, which derives a contradiction from the definitions of the Incarnation and of atemporalism, respectively. In the last section, I shall treat some possible objections to my argument and show that they do not solve the problem satisfactorily. (shrink)

This paper briefly proposes a weak relative identity strategy for the doctrine of the Trinity called the general partnership model. This model develops a logically consistent metaphysical constitution for the orthodox Christian doctrines of one divine substance and three divine persons. Moreover, the model rejects the rigid use of absolute identity in Trinitarian doctrine while modeling relative identity with an analogy of general partnerships in the United States.

I present Ned Markosian's episodic account of identity under a sortal, and then use it to sketch a new model of the Trinity. I show that the model can be used to solve at least three important Trinitarian puzzles: the traditional ‘logical problem of the Trinity’, a less-discussed problem that has been dubbed the ‘problem of triunity’, and a problem about the divine processions that has been enjoying increased attention in the recent literature.

This article aims to provide a metaphysical elucidation of a specific model of the doctrine of the Trinity: Monarchical Trinitarianism, within the formal, neo–Aristotelian ontological and metaphysical framework of Jonathan Lowe (i.e. his four–category ontology and serious essentialism). Formulating the model through this ontological and metaphysical framework will enable us to explicate it in a clear and consistent manner, and the important 'multiple–natures' problem raised against the proposed model will be shown to be ineffective.

Whether Trinitarianism is coherent depends not only on whether some account of the Trinity is coherent, but on which accounts of the Trinity count as "Trinitarian." After all, Arianism and Modalism are both accounts of the Trinity, but neither counts as Trinitarian (which is why defenses of Arianism or Modalism don’t count as defenses of Trinitarianism). This raises the question, if not just any account of the Trinity counts as Trinitarian, which do? Dale Tuggy is one of very few philosophers (...) to give explicit definitions of Trinitarian (versus Unitarian) theology. But they are no mere formalities. They are essential to his central criticisms of both historical and contemporary forms of Trinitarianism. In this paper, I offer my own definitions of Trinitarian and Unitarian theology, contrast them with Tuggy’s, and argue for the superiority of my definitions to Tuggy’s. If Trinitarianism and Unitarianism are what Tuggy says they are, the outlook for Trinitarianism is bleak indeed. If they are what I say they are, Tuggy’s central objection to Trinitarianism fails. To show what is at stake in these pairs of definitions, I examine a doctrine much neglected in Analytic Theology, but central to Nicene Trinitarianism—the Monarchy of the Father. (shrink)

There is a lively debate in contemporary Analytic Philosophy of Religion about the consistency of the Trinitarian doctrine. In this context, the notion of ‘mystery’ has become crucial. However, although it is currently considered the main challenge of Trinitarian theology, its definition remains rather partial and superficial. After a brief description of today’s Mysterianism, I analyse three ‘emblematic’ positions in light of the current debate: Aquinas, Leibniz and Hegel present three ways to believe in a mysterious Trinity. I will point (...) out a few possible weaknesses in the positions of the first two authors in order to better highlight the usefulness of the Hegelian position, often underestimated in the contemporary analytic debate. I will also analyse the connection between the three positions and their respective metaphysics, showing the epistemological premises (e.g., analogy and univocity) that need to be better investigated in the future.

This article aims to introduce a new solution to the Logical Problem of the Trinity. This solution is provided by utilising a number of theses within the field of contemporary metaphysics in order to establish a conceptual basis for a novel account and model of the doctrine of the Trinity termed Monarchical Aspectivalism, which will provide the means for proposing an alternative reading of the Athanasian Creed that is free from any consistency problems.

This article aims to provide an explication of the doctrine of the monarchy of the Father. A precisification of the doctrine is made within the building-fundamentality framework provided by Karen Bennett, which enables a further clarification of the central elements of the doctrine to be made and an important objection against it to be answered.

Why I thought it useful to offer an explanation of Hegel’s doctrine on the Incarnation was so that the reader may be empowered to identify Hegel’s influence in modern accounts of this mystery. Even if, in my view, Hegel’s interpretation of revealed religion differs greatly from Catholic Doctrine, it is not surprising to find the presence of some of his concepts in modern theology. In truth, what matters is not the theologian’s self-identification as Hegelian or as non-Hegelian, but whether or (...) not the theologian adopts Hegel’s concepts. This paper offers an explanation of the internal dynamism of Hegelian concepts and their relation to Christian doctrine in Hegel’s Phenomenology of Spirit. This research may help to show in what way it is possible to explain Christian religious doctrine with a philosophy other than the Thomistic one and how, at least in Hegel’s case, religious doctrine is changed and reduced to an erroneous philosophical content. Also, an attempt is made to show the internal “coherence” of this Hegelian re-reading of Christianity so that theologians may become more cautious about accepting an explanation of Christian doctrine simply because the Christian language is preserved in that explanation.

In a friendly interdisciplinary debate, we interrogate from several vantage points the question of “personhood” in light of contemporary and near-future forms of social AI. David J. Gunkel approaches the matter from a philosophical and legal standpoint, while Jordan Wales offers reflections theological and psychological. Attending to metaphysical, moral, social, and legal understandings of personhood, we ask about the position of apparently personal artificial intelligences in our society and individual lives. Re-examining the “person” and questioning prominent construals of that category, (...) we hope to open new views upon urgent and much-discussed questions that, quite soon, may confront us in our daily lives.

In the essay I analyse Micheletti’s three theses concerning: (a) the notion of mystery in relation to the “evidentialistic claim”; (b) analogical metaphysics in relation to “univocist immanentism” and to the importance of developing an analogical theism; (c) the fallibilistic conception of reason in relation to natural law, universalistic ethics and the so-called “essentialism” applied to individual human nature. I will try to show how deep is the intertwining and mutual implication of mystery and analogy – in metaphysics and theology, (...) in epistemology and ontology, in anthropology and ethics – and how Micheletti’s works have been an important step in bringing these two notions back to the center of the discussion that introduces oneself in the “question of God” and in the “question of Human being”.

Analytic theologians have proposed numerous “solutions” to the Logical Problem of the Trinity (LPT), mostly versions of Social Trinitarianism (ST) and Relative Identity Trinitarianism (RI). Both types of solution are controversial, but many hold out hope that further “Trinitarian theorizing” may yield some as yet unimagined, and somehow importantly different, solution to the LPT. I first give a precise definition of the LPT and of what would count as a solution to it. I then show how, though there are infinitely (...) many possible solutions, all solutions can be grouped together into a finite, exhaustive taxonomy, based precisely on those features which make them either controversial, heretical, or inconsistent. The taxonomy reveals why ST and RI have been the major proposed solutions, and also proves that there can be no importantly different, new solutions to the LPT. (shrink)

In the following paragraphs, I will describe ten strategies through which we can show the weaknesses of every form of theism based on the "One God", while postulating that the Trinity is a good solution. This approach follows up on Swinburne’s claims about the existence of a priori and a posteriori proofs for the existence of the Trinity (his proofs are part of the sixth strategy). Clearly, these strategies are not “new”: they have been advocated by many thinkers in the (...) past and in the present. I merely revived them, and brought them together in a kind of cumulative reasoning: the strength of them arises when these strategies are considered together, showing that the Trinity is a reasonable hypothesis even though it is contradictory. The proposed strategies lead to the conclusion that there must exist in God something similar to what we call ‘real relations’ and ‘multiplicity’; and in order for God to be relational, there must exist in Him some “distincts” that relate to one another. This is postulated by philosophical reasoning, not just by Revelation, and regardless of the choice to support a process metaphysics. As Trinitarian theology contains the mystery of eternal generation, the strategies do account for the fact that in philosophy we contemplate the mystery of eternal self-distinction and of all the other ‘self-actions’ of the One. The eternal generation remains mysterious, but it is the idea that best helps us describe how God is (One and Triune) and how he creates the world. God must be Triune in every theistic system. The One God is, as One, also Triune. The Unity-Trinity of the Principle is the only apophatic point that we can reach from many quarters. Once autonomous paths of reason have established that God is a Person and Persons, One-Multiple, Creator (communicated), Free, Relational and Infinite possibility, it therefore emerges that our most reliable hypothesis is that of the Trinitarian God.

Classical Trinitarians claim that Jesus—the Son of God—is truly God and that there is only one God and the Father is God, the Spirit is God, and the Father, Son, and Spirit are distinct. However, if the identity statement that ‘the Son is God’ is understood in the sense of numerical identity, logical incoherence seems immanent. Yet, if the identity statement is understood according to an ‘is’ of predication then it lacks accuracy and permits polytheism. Therefore, we argue that there (...) is another sense of ‘is’ needed in trinitarian discourse that will allow the Christian to avoid logical incoherence while still fully affirming all that is meant to be affirmed in the confession ‘Jesus is God.’ We suggest a sense of ‘is’ that meets this need.

There is an ongoing challenge in defining African theology because of two important reasons: the quest for a definitive African theology is a fairly recent pursuit and the vastness and diversity of the African continent. Given this, this article presents the complexity of defining African theology and its methodological approaches through a background sketch of the development of African theology. Regardless of many definitions of African theology and its purposes, the article acknowledges African Christian theology as theology that should be (...) derived from the interplay between Scripture, Christian tradition and African cosmology. In deriving theology from the aforementioned aspects, African theology should also seek to develop contextual African theologies with global relevance. In this way, African theology can claim its space in the universal church. Although we are conscious of the values and challenges associated with the task of doing African theology, we argue for its necessity. We further argue that if the centrality of Scripture is maintained in the African theological endeavour, it will cause African theologies to have some shared reference point with other Christian theologies and hence engaging globally, while contributing unique African perspectives to global theological discourse.

The paper is the summary of a wider work, a research program. The hypothesis is that if Fundamental Ontology is apophatic – that is, if it has the same dialectical nature (relationality-substantiality) as the Trinity – we can accept that Trinity is also apophatic. The apophatic-relational explanation may sound odd, but it is the most honest one, because it does not hide the problems under the carpet. What emerges is a coherent form of Trinitarian Theism – since there is correspondence (...) between the human (un)ability to know the two levels of reality (the World and God) – that is based on an inevitable relational-apophatic paradigm. The apophaticism that we see in the Trinity (and in ontology) ensures that Trinitarian Theism can neither be proven nor disproven. (shrink)

A little essay on the notion of person in Albert the Great. He bases on Alexander of Hales and develops his notion of person from the classical definition of Boethius.

Gregory the Great depicts himself as a contemplative who, as bishop of Rome, was compelled to become an administrator and pastor. His theological response to this existential tension illuminates the vexed questions of his relationships to predecessors and of his legacy. Gregory develops Augustine’s thought in such a way as to satisfy John Cassian’s position that contemplative vision is grounded in the soul’s likeness to the unity of Father and Son. For Augustine, “mercy” lovingly lifts the neighbor toward life in (...) God. Imitating God’s own love for humankind, this mercy likens the Christian to God’s essential goodness and, by this likeness, prepares him or her for the vision of God, which Augustine expects not now but only in the next life. For Augustine, the exercise of mercy can—when useful—involve a shared affection or understanding. Gregory makes this shared affection essential to the neighborly love that he calls “compassion.” In this affective fellowship, Gregory finds a human translation of the passionless unity of Father and Son—so that, for Gregory, compassion becomes the immediate basis for and consequence of seeing God—even in this life. Compassion does not degrade; rather, it retrenches the perfection of contemplation. Reconciling compassionate activity and contemplative vision, this creative renegotiation of Augustine and Cassian both answered Gregory’s own aspirations and gave to the tumultuous post-Imperial West a needed account of worldly affairs as spiritual affairs.

Τρόπος ὑπάρξεως bei den Kappadokischen Vätern und bei St. Maximus Confessor In dieser Arbeit werden wir versuchen, zu erörtern, was der Begriff τρόπος ὑπάρξεως bei den Kappadokischen Vätern im Kontext ihrer Triadologie bedeutet. Unserer Meinung zufolge ist die Reduktion der Bedeutung des Begriffs τρόπος ὑπάρξεως auf individuelles Wesen mit Charakteristika kein entsprechendes Abbild der Absicht der Väter. Ganz im Gegensatz, der Begriff τρόπος ὑπάρξεως dient bei ihnen als Unterstützung für die Konstituierung des Begriffs der Hypostase, welcher neben der Bedeutung eines (...) individuellen Wesens mit Charakteristika auch Relation als Schlüs-selmoment ihrer personalistischen Ontologie besitzt.

St. Maximus the Confessor claims that the logos of created beings represents their essence as an icon. This claim gives us the opportunity to understand the term essence as an dynamic reality and not as a static given. Essence is not something that the being is, but what it is supposed to be. The idea of icon is herein present as ultimately ontological. The icon is no mirror of reality, but rather its eschatological realization. That which will be uncovers the (...) truth of the being. This way, St. Maxius has founded a dynamic ontology, which is a fundamental step away from the Hellenic heritage. The equalization of the essence of beings and icon is only possible in an Eucharistic view of the world, wherein the Eucharist represents in an iconic way the presence of the eschatological truth in history.

The Author proposes to describe the possible foundations of a Trinitarian theism that may be a philosophically adequate translation of the Johannine declaration: “God is love”, introduced by some contemporary thinkers as a key to resolving some aporias within classic theism. This is done by way of analysis of Trinitarian ontology and relational ontology, for which there is an attempt to provide a shareable phenomenological basis. The paper then goes on to questions of epistemology (hyperphatic theology) linked to the ability (...) of human reason and human language to express the categories introduced in this analysis, categories that are nothing else but a renewed philosophical appreciation of the terminology proper to Trinitarian speculation.

The author contextualizes the Problem of Evil in Open Theism system, listing its main theses, primarily the logic-of- love-defense (and free-will-defense) connected to Trinitarian speculation. After evaluating the discussion in Analytic Philosophy of Religion, the focus is on the personal mystery of evil, claiming that, because of mystery and vagueness, the Problem of Evil is undecidable. Recalling other schools of thought (Pareyson: ontology of freedom; Moltmann: Dialectical theology; Kenotic theology; Original Sin hermeneutics), the author tries to grasp their common insights. (...) One of them is the evident explanatory failure of theodicies, expressed in the antinomian statements ‘God is not innocent’. The author follows these insights, developing the concept of Eternal Immolation (Bulgakov), arguing that, without a proper understanding of its mystery (what is, and what is not), theistic theodicy could remain compromised. ‘Eternal Immolation’ is considered consequent – or already present – in recent speculations, it stands or falls when we accept that these reveal some unresolved points in Christian doctrine. Hence, ‘Eternal Immolation’ becomes a coordinating-concept, able to bring together their assumptions: several kinds of kenosis, the ontology of freedom with a logic-of-love defense, strongly linked to a libertarian human freedom, and the acknowledgement of the unresolved mystery of evil.

Within contemporary evangelical theology, a peculiar controversy has been brewing over the past few decades with regard to the doctrine of the Trinity. A good number of prominent evangelical theologians and philosophers are rejecting the doctrine of divine processions within the eternal life of the Trinity. In William Hasker’s recent Metaphysics and the Tri-Personal God, Hasker laments this rejection and seeks to offer a defense of this doctrine. This paper shall seek to accomplish a few things. In section I, I (...) shall first set the stage for a proper understanding of the discussion. Section II will articulate the basic Trinitarian desiderata that must be satisfied by any model of the doctrine of the Trinity. This will help one understand the debate between Hasker and the procession deniers. Section III will offer an articulation of what the doctrine of divine processions teaches. Section IV will examine Hasker’s defense of the doctrine point by point. I shall argue that his defense of the doctrine of the divine processions fails. (shrink)

I am the way and the truth and the life. John 14:6.

Contemporary accounts of the Trinity and Incarnation sometimes employ aspects of Peter Geach's theory of relative identity. Geach's theory provides an account not merely of identity predicates, but also proper names and restricted quantification. In a previous work I developed an account of the doctrines of the Trinity and Incarnation incorporating these three aspects of Geach's theory and tried to show how each might contribute to our understanding of the doctrines. Joseph Jedwab has recently argued that my account—or any that (...) employs Geach's treatment of restricted quantifiers—leads to serious doctrinal errors. I reply to his criticisms. (shrink)

The article argues for the variant ‘tractabimus’ in Book 8, ch. 1 of Augustine’s De Trinitate as opposed to the reading ‘tractavimus’ adopted in the Corpus Christianorum edition, and explains the implications of this variant for the understanding of the overall structure of the work.

I try to lay bare some of the conceptual space in which one may be a Social Trinitarian. I organize the paper around answers to five questions. These are: How do the three Persons of the Trinity relate to the Godhead? How many divine beings or gods are there? How many distinct centers of consciousness are there in the Godhead? How many omnicompetent beings are there? How are the Persons of the Trinity individuated? I try to make clear costs and (...) benefits of various answers to these questions. (shrink)

The theological teachings of John Philoponus are important for several reasons: a) to see the real achievements and influences of Aristotelian logic in regard to theology, b) to see the real consequences of not accepting hypostasis as relational and ontologically based and c) to assess the real consequences of such teachings for Triadology and Christology.

Goetz outlined legal models of identical entities that include natural persons who are identical to a coregency and natural persons who are identical to a general partnership. Those entities cohere with the formula logic of relative identity. This essay outlines the coexistence of relative identity and numerical identity in the models of identical legal entities, which is impure relative identity. These models support the synthesis of Relative Trinitarianism and Social Trinitarianism, which I call Relative-Social Trinitarianism.

A descriptive polytheist thinks there are at least two gods. John Hick and Richard Swinburne are descriptive polytheists. In this respect, they are like Thomas Aquinas and many other theists. What sets Swinburne and Hick apart from Aquinas, however, is that unlike him they are normative polytheists. That is, Swinburne and Hick think that it is right that we, or at least some of us, worship more than one god. However, the evidence available to me shows that only Swinburne, and (...) not Hick, is a cultic polytheist: he actually worships more than one god. I conclude that only Swinburne is a polytheist par excellence. (shrink)

In this paper, I will offer an analogy between the Trinity and extended simples that supports a Latin approach to the Trinity. The theoretical tools developed to discuss and debate extended simples in the literature of contemporary analytic metaphysics, I argue, can help us make useful conceptual distinctions in attempts to understand what it could be for God to be Triune. Furthermore, the analogy between extended simples and the Trinity might surprise some who find one of these at least plausibly (...) possible and the other incoherent. (shrink)

The theorizing about the doctrine of the Trinity by contemporary analytic philosophers of religion has recently been imbued with an air of enthusiastic excitement and self-confidence. My intuition is that there’s room for saying something more in support to the embarrassment and puzzlement traditionally related to the predication of God’s onefoldness and threefoldness. My purpose is to deliver a general argument for (weak) trinitarian skepticism. My view is that the argument provides substantive reasons in support to the common sense intuition (...) that either God’s onefoldness and threefoldness aren’t actually compatible or God’s onefoldness and threefoldness aren’t robustly construed.

For among most contemporaries, the concept of Eros seems to have nothing to do with Christianity. Sifting through the psychoanalysis of sexual fantasy, theologically it says nothing. Our study gives reasons showing that for theologians since the dawn of the Christian era, Eros-love plays a fundamental role.. The connotations of this concept, however, are different from those of today, when its sensory meaning is more restricted to sexuality. Greek theologians of the first centuries after Christ, taught the concept of Plato (...) enshrined as a unifying enthusiasm, the attraction of inferior to superior states, as “hungry and thirsty” for something continuously higher, developing, and enriching the connotation. The work of Dionysius Areopagite, the Idea of Good, leads us step by step up the ascent of the erotically chaste, and is identified with the One-God, who is the very source of love. Consequently, Eros-love originates from God, Eros- love being not only an ascending but firstly a descending love, which calls for a reciprocal communion. (shrink)

The Greek model of the Trinity, based on the Theological Orations of Gregory of Nazianzus, treats the Trinitarian relations as connections between the Father and the two other persons: the Son and the Holy Spirit. The two relations have to be heteronymous, and have to be interpreted from the extreme realistic position. The Latin Trinitarian model, based on Boethius’ De Trinitate, treats relations as three subsistent persons. The relations have to be unidirectional: from the Father to the Son, and from (...) both of them to the Holy Spirit. Both models are adequate and effective, but incompatible. One of the consequences of this incompatibility is the problem of filioque: the introduction of an additional relation of procession into the Greek model as well as the exclusion of this relation from the Latin model result in the inadequacy of the models. From the point of view of the complementability of a model, the Greek model allows introduction of new elements, while the Latin model does not. The soteriological consequences are such that the Greek model welcomes a human person to establish a unique relation with the person of the Father, which leads to the theosis of a creature. The Latin model requires the saving relation to be established with the whole Trinity, and theosis is not supported. (shrink)

The philosophical thought of Massimo Cacciari and the conceptual issues of « open theism » are two speculative routes apparently very distant from each other. This contribution highlights the common goal in their going to the root of philosophic problems in order to seek an answer: they think of a divine way of becoming explaining the reason of both the reality of the world and the paradoxical reality of human freedom. The two routes tend to converge and recover concepts pertaining (...) to the Trinitarian speculation whose philosophical « translation » in philosophy passes, today, through the relational and trinitarian ontology, and also the « iperphatic » theology. In this convergence there is ground for thinking not only a truly Trinitarian theism, but also a Trinitarian philosophy, which considers Trinity as the essential summit of a good metaphysics.

Professor Christopher Stead was Ely Professor of Divinity from 1971 until his retirement in 1980 and one of the great contributors to the Oxford Patristic Conferences for many years.

As a case study to illustrate and diagnose his (...) approach, I shall focus on a debate between Stead and Rowan Williams about the significance of the word idios in Arius's theology (in the course of which I also make some suggestions of my own about the issue).

Trinitarians claim there are three Divine persons each of which is God, and yet there is only one God. It seems they want three to equal one. It just so happens, some metaphysicians claim exactly that. They accept Composition as Identity: each fusion is identical to the plurality of its parts. I evaluate Composition as Identity's application to the doctrine of the Trinity, and argue that it fails to give the Trinitairan any options he or she didn't already have. Further, (...) while Composition as Identity does give us a new way to assert polytheism, its help requires us to endorse a claim that undercuts any Trinitarian motivation for the view. (shrink)

An argument for the rationality of religious belief in the existence of God is defended. After reviewing three preconditions for rational belief, I show reasons to privilege the criterion of consistency. Taking the inconsistency of the religious belief in God and the belief in the scientific world picture as the impediment to a rational belief in God, I propose that we can overcome this objection by assuming, firstly, that God is a universal class. This allows us to put the problem (...) of God in set-theoretic terms, such that the antinomy that follows from such an assumption can be overcome by assuming that God is not a subject but a strict class that cannot be individuated. I conclude that that the self-contradictory nature of God does not prevent the believer from making a rational, ethical assessment that the contradiction resides in the possibility of using language to explain his existence, but that this does not make belief in the existence of God unjustifiable – on the contrary. In this way, we can say statements that claim God exists are justifiable. (shrink)

P. T. Geach has argued that it is impossible to demonstrate that the doctrine of the Trinity is consistent. I try to show why -- on a common understanding of the notion of consistency -- his reasoning is flawed and why, on Geach’s own principles, one should expect that if the doctrine of the Trinity is true then it will be possible to prove that the doctrine is consistent, and it will be possible to do this in a way that (...) makes no appeal to the truth of any religious doctrine.

The Christian doctrine of the Trinity poses a serious philosophical problem. On the one hand, it seems to imply that there is exactly one divine being; on the other hand, it seems to imply that there are three. There is another well-known philosophical problem that presents us with a similar sort of tension: the problem of material constitution. We argue in this paper that a relatively neglected solution to the problem of material constitution can be developed into a novel solution (...) to the problem of the Trinity. (shrink)

Theology is the preeminent academic discipline during the Middle Ages and, as a result, most of great thinkers of this period are highly trained theologians. Although this is common knowledge, it is sometimes overlooked that the systematic nature of medieval theology led its practitioners to develop full treatments of virtually every area within philosophy. Indeed, theological reflection not only provides the main context in which the medievals theorize about what we would now recognize as distinctively philosophical issues, but it is (...) responsible for some of their most significant philosophical contributions. To give just a few examples: it is problems with the Christian doctrine of the Incarnation that prompt medievals to develop the notions of ‘substance’ and ‘person’ in striking and original ways; it is problems with the doctrine of the Eucharist that lead them to consider the possibility of ‘accidents that do not inhere’; and it is problems of..

In a recent article, Edward Wierenga defends a version of Social Trinitarianism according to which the Persons of the Trinity form a unique society of really distinct divine beings, each of whom has its own exemplification of divinity.

Reprinted in Philosophical and Theological Essays on the Trinity, Oxford, 2009, eds Michael Rea and Thomas McCall. In this essay, I assess a certain version of ’social Trinitarianism’ put forward by J. P. Moreland and William Lane Craig, ’trinity monotheism’. I first show how their response to a familiar anti-Trinitarian argument arguably implies polytheism. I then show how they invoke three tenets central to their trinity monotheism in order to avoid that implication. After displaying these tenets more fully, I argue (...) that Trinitarians would do well to hold Moreland’s and Craig’s trinity monotheism at arms length. (shrink)
