Scott Williams’s Latin Social model of the Trinity holds that the trinitarian persons have between them a single set of divine mental powers and a single set of divine mental acts. He claims, nevertheless, that on his view the persons are able to use indexical pronouns such as “I.” This claim is examined and is found to be mistaken.

In “Unity of Action in a Latin Social Model of the Trinity,” I objected to William Hasker’s Social Model of the Trinity on the grounds that it does not secure the necessary agreement between the divine persons. Further, I developed a Latin Social model of the Trinity. Hasker has responded by defending his Social Model and by raising seven objections against my Latin Social Model. Here I raise a new objection against Hasker on the grounds that it (...) is inconsistent with Conciliar Trinitarianism, and I respond to the seven objections and in so doing further develop the Latin Social Model.

Scott Williams has provided a careful and detailed response to my critique of his Latin Social model of the Trinity. I reply to his defense, and I argue that this model is, in fact, indefensible.

Dale Tuggy argues that my trinitarian views are in conflict with the theology of the New Testament; the New Testament, rather, is unitarian. I show several flaws in this argument, and point out the New Testament evidence that eventually led to the formulation of the doctrine of the Trinity.

Spermatozoa reach the fallopian tube during ovulation by traveling through the female reproductive tract mucus. This non‐Newtonian viscoelastic medium facilitates spermatozoon movement to accomplish fertilization or, in some cases, blocks spermatozoon movement, leading to infertility. While rheological properties are known to affect spermatozoon motility with in vitro models using synthetic polymers, their precise effects in vivo are understudied. This paper reviews the rheological measurements of reproductive tract mucus during ovulation in humans and model animals, focusing on viscosity and its potential (...) effect on spermatozoa. Mucus viscosity in the female reproductive tract's different compartments is poorly understood. While information on this subject is incomplete, most mammals appear to have a viscosity decrease along their female reproductive tracts. Based on this sparse information, we hypothesize that viscosity changes in female reproductive tracts may guide spermatozoa to eggs, a novel concept that could improve our understanding of reproductive biology.

In recent analytic literature on the Trinity we have seen a variety of "social" models of the Trinity. By contrast there are few "non-­‐social" models. One prominent "non-­‐social" view is Brian Leftow's "Latin Trinity." I argue that the name of Leftow's model is not sufficiently descriptive in light of diverse models within Latin speaking theology. Next, I develop a new "non-­‐social" model that is inspired by Richard of St. Victor's description of a person in conjunction with my (...) appropriating insights about indexicals from David Kaplan and John Perry. I point out that the copula in tokens of statements like, "I am the Father," is an ambiguous term and when used by a certain divine person a different proposition is affirmed. Central to this model is the claim that the copula bears the "is of identity" and the "is of numerical sameness without identity." Further, I show that Leftow's model employs two concepts of "person," a Lockean one and a Boethian one, and mine employs Richard of St. Victor's. I describe Leftow's model as a "hard non-­‐social" model and mine as a "soft non-­‐social" model that is nearer to some social models. I conclude that Leftow's model is not the lone candidate among "non-­‐social" models and that the variety of "non-­‐social" models has yet to be exhausted. (shrink)

I develop a Latin Social model of the Trinity that is an extension of my previous article on indexicals and the Trinity. I focus on the theological desideratum of the necessity of the divine persons’ unity of action. After giving my account of this, I compare it with Swinburne’s and Hasker’s social models and Leftow’s non-social model. I argue that their accounts of the divine persons’ unity of action are theologically unsatisfactory and that this unsatisfactoriness derives from a (...) modern conception of personhood according to which distinct and incommunicable intellectual acts and volitional acts are necessary conditions for one’s being a person. I argue that the Latin Social model is preferable to the modern-personhood models because it is simpler in explanatory economy with regard to securing the necessity of the divine persons’ unity of action.

In the interval between the time of the Reformation and today, large numbers of Christians seem quietly to have shifted their allegiance from one God to another, leaving themselves with the doctrine of the Trinity but no longer retaining the God whom it adumbrates.

Jeffrey Brower and Michael Rea have proposed a model for the Trinity using a particular understanding of the relation of material constitution. I examine this model in detail and conclude that it cannot succeed. I then suggest, but do not fully develop, a model of the Trinity using an alternative notion of constitution.

Brian Leftow has proposed a “Latin” doctrine of the Trinity according to which “the Father just is God,” and so also for the Son and the Spirit. I argue that Leftow’s doctrine as he presents it really does have the consequence that Father, Son, and Spirit are all identical, a consequence that is inconsistent with orthodox Trinitarianism. A fairly minor modification would enable Leftow to avoid this untoward consequence. But the doctrine as modified will still retain a strongly modalistic (...) flavor: it implies, among other things, that the prayers of Jesus in the Gospels are instances of God-as-Son praying to himself, namely to God-as-Father. If this is found unacceptable, Leftow may have been too quick to dismiss Social Trinitarianism. (shrink)

Anselm examines and defends the doctrine of the Trinity in three works, the ’Monologion’, ’On the Incarnation of the Word’, and ’On the Procession of the Holy Spirit’. Using the ’Monologion’ as a base, this essay connects Anselm’s doctrine of God’s metaphysical simplicity to his Trinitarian views. Anselm is concerned to avoid the heresies of Arianism, tritheism, and modalism. Because he regards the doctrine as transcending the powers of human reason and thus incapable of being proved, his argumentation proceeds (...) by adopting the analogies of memory, understanding, and will used earlier by Augustine, and by modifying Augustine’s analogy of water as headwaters, river, and drinking water.

Dale Tuggy argues that his divine-deception argument against social Trinitarianism remains unscathed, in spite of my recent objections. I maintain that his argument is question-begging and exegetically weak, and does not succeed in refuting social Trinitarianism.

Michael Rea and Jeffery Brower have offered a provocative new model of the Trinity on the analogy of the Aristotelian solution to the problem of material constitution. Just as a fist and a hand can be distinct entities composed of a common matter and yet numerically the same object, so the persons of the Trinity can be distinct entities (persons) composed of a common "matter" (the divine essence) and yet numerically the same object (God). I express doubts about (...) the degree to which this analogy sheds light on the doctrine of the Trinity due to the disanalogy that neither God nor the Trinitarian persons are to be thought of as composed of any sort of stuff and to the model’s lack of explanatory power as to how a common matter can be simultaneously imbued with seemingly incompatible forms to constitute one object.

I argue that there is a hitherto unrecognized connection between Henry of Ghent’s general theory of real relations and his Trinitarian theology, namely the notion of numerical sameness without identity. A real relation (relatio) is numerically the same thing (res) as its absolute (non-relative) foundation, without being identical to its foundation. This not only holds for creaturely real relations but also for the divine persons’ distinguishing real relations. A divine person who is constituted by a real relation (relatio) and the (...) divine essence is numerically the same thing (res) as the divine essence without being identical to it. Further, I compare Mark Henninger’s and Jos Decorte’s interpretations of Henry’s general theory of real relations and show that Henninger’s is to be preferred and how it is consistent with my interpretation. I argue that the difficulty with Decorte’s interpretation stems, in part, from his misrepresentation of Henry’s Trinitarian theology. Subsequently, I fill in some missing pieces to Decorte’s presentation of Henry’s Trinitarian theology, and this in turn shows why Henninger’s interpretation in conjunction with mine is to be preferred.

WilliamsThe disagreement between William Hasker and myself includes discussion of Gregory of Nyssa’s Trinitarian theology, the relevance of Conciliar Trinitarianism for evaluating models of the Trinity, and the defensibility of my Latin Social model of the Trinity. I respond to Hasker’s recent objections regarding all three areas. I contest Hasker’s interpretation of Gregory and argue that Gregory is indeed a “one-power” theorist. I make historical connections between Gregory’s Trinitarian theology and Pope Agatho’s “one-power” statements that were endorsed by (...) the Sixth Ecumenical Council (680-681ce); and I make explicit the Sixth Ecumenical Council’s interest in the general issue of how “ousia” and “hypostasis” pertain to the Trinity and the Incarnation. Lastly, I defend and develop the Latin Social model in response to Hasker’s five objections. In light of my findings in the Sixth Council, I retire the name “Latin Social Trinity” for my model and replace it with a name more apt for my model, that is, the “Conciliar Social Trinity.”.

The doctrine of the Trinity affirms that there are three divine Persons, each of whom is fully God, who have between them a single concrete divine nature. This paper attempts two show that, and how, these claims are coherent rather than contradictory. In the process a model for the Trinity is proposed using the notion of constitution.

The doctrine of the Father’s begetting the Son in his divine nature, despite its credal affirmation, enjoys no clear scriptural support and threatens to introduce an objectionable ontological subordinationism into the doctrine of the Trinity. We should therefore think of Christ’s sonship as a function of his incarnation, even if that role is assumed beginninglessly.

This article explores the interrelations among religious, moral and political power in an analogy to the Christian concept of ‘perichoresis’ of the Trinity. Starting with beliefs about power, the endoxa, the article explores, first, moments in Western thought to show how power has been grounded in God or gods and in the vitalities of nature. In each case, ultimately speaking, ‘might makes right’. Within this history the article also charts the ‘axial breakthrough’ in Christianity that places ‘ethical’ limits on (...) religious and political power. In a second step, the works of Reinhold Niebuhr and Stanley Hauerwas are explored in order to show that current Christian ethics is caught in an aporia: it asserts the reality of power in history and the ‘world’, but also the ultimate claim of Christian love. The article concludes that Christian ethics needs a differentiated conception of power and a renewed conception of ‘conscience’ as the mode of moral being within complex social systems. (shrink)

A fellow of Trinity College, Cambridge, and of the Royal Society, William Clifford (1845–79) made his reputation in applied mathematics, but his interests ranged far more widely, encompassing ethics, evolution, metaphysics and philosophy of mind. This posthumously collected two-volume work, first published in 1879, bears witness to the dexterity and eclecticism of this Victorian thinker, whose commitment to the most abstract principles of mathematics and the most concrete details of human experience resulted in vivid and often unexpected arguments. Volume (...) 2 shows Clifford's thorough engagement with scientific thought as a method for illuminating ethical and moral questions. Essays such as 'Body and Mind', 'On the Scientific Basis of Morals' and 'The Ethics of Belief' all variously demonstrate Clifford's core tenet: that beliefs - whether they guide human action or scientific enquiry - 'can never suffer from investigation'.

Introduction: -/- It is likely that Boethius (480-524ce) inaugurates, in Latin Christian theology, the consideration of personhood as such. In the Treatise Against Eutyches and Nestorius Boethius gives a well-known definition of personhood according to genus and difference(s): a person is an individual substance of a rational nature. Personhood is predicated only of individual rational substances. This chapter situates Boethius in relation to significant Christian theologians before and after him, and the way in which his definition of personhood is a (...) particular answer to the question, “Jesus has two natures, a divine nature and a human nature, but is one what?” Among Greek (and Syriac) speaking theologians, the typical answer is that Jesus is one ‘hypostasis’. Among Latin speaking theologians, the typical answer is that Jesus is one ‘persona’. It is Boethius’s definition of ‘persona’ that inaugurates personhood as such in Latin speaking theology. Although the Greek and Syriac theologians that I survey come close to a concept of personhood as a distinct category, they do not have such a concept and did not need it for their theological purposes. I show that Rusticus the Deacon is an early witness to this Latin theological invention, and also show that for later Latin theologians, the rationality condition for personhood does very little metaphysical work for their Trinitarian theology or Christology. -/- Further, this chapter surveys Patristic and Medieval Christian theologians’ answers to the question, “God the Father, God the Son, and God the Holy Spirit are one God, but each is one what?” The same replies as above are typically given by Christian theologians. These two theological questions frame the discussion about personhood (and ‘hypostasis’) and put a boundary around what a satisfying account of personhood (and ‘hypostasis’) would be. -/- In contemporary philosophy, there is a lot of attention paid to the rationality condition for personhood. But if we look at the text in which Boethius defines a person, we do not find any precise criteria for it. In other texts, he says that a rational being is one compatible with (capable of) thought and free choice of the will. What we find is that detailed discussion of personhood shows up in theological questions about the Trinity and Incarnation, but not in e.g., applied ethics. The intrusion of personhood into contemporary applied ethics with a focus on detailed and disputed criteria for rationality as a condition for personhood seems to be a modern development. From a Patristic and Medieval Christian theology point of view, trying to find just the right detailed criteria for rationality in order to define personhood is a wild goose chase. This chapter makes clear another contribution that Christian theology had for personhood. Given the theological issues at play in developing a notion of personhood, Christian theologians came to posit that e.g., an individual human is a person contingently (i.e. not essentially), but God the Father, God the Son, and God the Holy Spirit are each a person essentially. The contingency for created persons is not based on whether e.g., an individual human has conscious acts (as might be the case for John Locke) but on the possibility of a divine person’s assuming e.g., an individual human nature. -/- This sampling of Christian intellectual history spans over one thousand years. I make no claim of being exhaustive. The chapter consists of six sections, where each section covers significant historical conversation partners who together represent the sorts of things that Patristic and Medieval Christian theologians where concerned with in theorizing about ‘persona’ or ‘hypostasis’. -/- 1.

In lieu of an abstract, here is a brief excerpt of the content:Dominus Deus Noster Deus Unus Est:Aquinas on Divine UnityArchbishop Rowan Williams"The Lord our God is one LORD," says the Shema (Deut 6:4), echoed by Christians and Muslims alike. "We believe in one God," the Nicene Creed announces; and the Shahada's "There is no deity but God" affirms the same. But at first sight, Christian theology looks like the outlier here, as St. Thomas obliquely acknowledges when, early in (...) his discussion of the Trinity (Summa theologiae [ST] I, q. 30, a. 1, obj. 1 and ad 1), he quotes Boethius: "That [alone] is truly one in which there is no numeration" (obj. 3). If there is a plurality of relation in God, there is something that can be enumerated, says Thomas. This objection is duly met by distinguishing between "absolute" plurality and the mutually definitory relations of the Trinitarian life which rule out any "composition" in God. But, for this fully to make sense, we must return to Thomas's explicit discussion of divine unity (ST I, q. 11). The present essay attempts a brief examination of how divine unity is understood in this quaestio, in the hope of clarifying an aspect of Aquinas's Trinitarian thought, and also of suggesting ways of developing an implicit theme of some significance for contemporary theology.It is still a textbook commonplace that "Western" Trinitarian theology begins from the divine unity and treats the distinction of the divine persons only in the light of this prior reality. The eloquent polemic of Orthodox theologians like Vladimir Lossky has played a major role in canonizing this supposed opposition. He writes, for example, that Western Trinitarianism treats the relationships of the divine hypostases as "a system of relationships within the one essence: something logically posterior to the essence," with [End Page 555] the distinguishing "relations of origin" (originary fatherhood, generatedness, procession) as "more or less swallowed up in the nature or essence."1 Examples could be multiplied, from Lossky and many others, and from Western theologians influenced by this characterization.2 The very structure of Aquinas's Summa theologiae, with the quaestiones de Deo uno preceding those de Trinitate, is sometimes adduced in support of this analysis of the ambiguities and inadequacies of Thomist Trinitarianism, and of a general Western resistance to the radical personalism of authentic patristic theology.But, polemic apart, what is Aquinas actually saying in his treatment of divine unity, primarily in ST I, q. 11? The four articles of the quaestio deal with whether saying that something is "one" actually tells us anything beyond the postulation of something as a coherent subject/substance; with whether unity and plurality are simply opposed and incompatible notions; with whether it is right to say that God is one, and if so, whether he is maxime unus, one in a unique and unsurpassable sense. Basic to his argument, as we shall see, is something touched on briefly in ST I, q. 30, a. 1, where his response (ad 3) to the Boethian formulation associates divine unity with simplicity—that is, with non-composition:3 affirming the divine unity is, crucially, denying the applicability of certain kinds of discourse in theology. But, as we shall see, part of the abiding importance of Aquinas's discussion is, perhaps unexpectedly, to open the door to a new ontological perspective in which laying out the difference between different senses of "unity" allows for the development of a more systematically relational metaphysics. Related to this is the distinction drawn (especially in ad 2 of [End Page 556] a. 3) between "mathematical" and "metaphysical" unity; one of the problems with a good deal of modern criticism of Western Trinitarianism is a failure to reckon with the diversity of ways in which "unus est" might be used, and St. Thomas is in fact abundantly clear about the senses that must be ruled out in theology—including any sense that would oppose an "individual" essence to "multiple" hypostases, as if the divine essence were itself a sort of numerically identified individual.The ground for this is laid in the first article. If we say that something is "one," we are surely offering a determination of it, specifying one way of... (shrink)

Human beings exist in one of two sorts of solidarity, according to St. Paul—the solidarity of sin or alienation ‘in Adam’ or the solidarity of life-giving mutuality in Christ. There can be no Christian theology of the human that is not a theology of communion—which converges with the conviction that our creation in the divine image is creation in relationality. The image of God is not a portion or aspect of human existence but a fundamental orientation towards relation. This understanding (...) of the divine image in turn points to the way in which—as the Orthodox theologian Vladimir Lossky stresses—a proper understanding of the nature of personal being depends upon a proper grasp of the divine image, including the fact that it is always an image of the divine ‘filiation’—the eternal relation of Word to the Father in the Trinity. Our personal flourishing is a filial dependence that liberates and empowers. And what is ‘empowered’ is the human vocation to make reconciled sense of the material world of which we are part, articulating and serving its Godward meaning, so that we may see our humanity as essentially a priestly calling within the reconciling priesthood of Christ, in whom all things cohere.

The characteristic claim of Christianity, as codified at Chalcedon, is that God the Son, the second person of the Trinity, is numerically the same person as Jesus of Nazareth. This article raises three questions that appear to threaten the coherence of orthodox Chalcedonian incarnationalism. First, how can one person exemplify seemingly incompatible natures? Second, how can one person exemplify seemingly incompatible non-nature properties? Third, how can there be one person if the concept of incarnation implies that one person incarnates (...) himself as another person? The attempts of C. S. Lewis and T. V. Morris to deal with these difficulties are examined and found inconclusive. (shrink)

This volume presents fourteen of William E. Mann's essays on three prominent figures in late Patristic and early medieval philosophy: Augustine, Anselm, and Peter Abelard. The essays explore some of the quandaries, arguments, and theories presented in their writings. The essays in this volume complement those to be found in Mann's God, Modality, and Morality. While the essays in God, Modality, and Morality are primarily essays in philosophical theology, those found in the present volume are more varied. Some still deal (...) with issues in philosophical theology. Other essays are aporetic in nature, discussing cases of philosophical perplexity, sometimes but not always leaving the cases unresolved.All the essays display, directly or indirectly, the philosophical influence that Augustine has had. His Confessions is a rich source for philosophical puzzlement. Individual essays examine his reflections on the alleged innocence of infants, which raises questions about cognitive, emotional, and linguistic development; his juvenile theft of pears and its relation to moral motivation; and his struggle with and resolution of the problem of evil. One essay presents the rudiments of an Augustinian moral theory, rooted in his understanding of the Sermon on the Mount. Another essay illustrates the theory by discussing his writings on lying. Mann argues that Abelard amplified Augustine's moral theory by emphasizing the crucial role that intention plays in wrongdoing.Augustine bequeathed to Anselm the notion of. (shrink)

Aquinas' theology can be understood only if one comes to grips with his metaphysics of being. The relevance of this perspective is exhibited in his treatment of topics like creation, goodness, happiness, truth, freedom of the will, the unity of the human being, prayer and providence, God's personhood, divine love, God and violence, God's unknowablility, the Incarnation, the Trinity, God's existence, theological language and even laughter. This book endeavors to treat these questions in a clear and convincing language. Is (...) there a better method for improving one's own theology than by grappling with the arguments of Thomas Aquinas? (shrink)

HaskerI argue that Scott M. Williams’s “Latin/Conciliar Social Trinity” is unable to give a coherent account of some undisputed divine actions. The reason for this lies in Williams’s failure to recognize the different senses in which the trinitarian Persons can be said to have “powers.”.

This chapter is about personhood in relation to ethics and to conciliar Christian theology, and how concepts of personhood may discriminate against profoundly cognitively disabled human beings. (By ‘conciliar Christian theology’ I mean the Christian theology that is articulated in, or endorsed by, the first seven ecumenical councils.) -/- I believe we can learn several things about personhood by looking at these two topics together. By examining ancient and medieval concepts of personhood and some modern conceptions of personhood we gain (...) a better grasp of the variety of concepts and what substantive work they were intended to do. By becoming familiar with (part of) the history of concepts of personhood we are better situated to appreciate and judge the theoretical work that these concepts were intended to do and what consequences they have in ethical and theological theorizing. -/- In the first section I tell a select history of moral philosophers theorizing about personhood and discuss these in relation to human beings with profound cognitive disability. I focus on John Locke, Immanuel Kant, and Mary Anne Warren. In the “When Personhood Is Discriminatory” section I argue that concepts of personhood, especially modern concepts of personhood, are typically used in a manner that discriminates against human beings with profound cognitive disabilities. I give two arguments against discriminatory uses of personhood, the Moral Shift Argument and the Argument against Exclusive Personhood. Although the Moral Shift Argument is deductively valid, it probably has little persuasive power over those who do not share the moral belief that profoundly cognitively disabled human beings are equal members of the moral community. However, the Argument against Exclusive Personhood has more argumentative force because it denies the claims that personhood is “self-evident” and that it is “obvious” to everyone. In the following section I survey a select history of concepts of personhood in order to establish the claims that concepts of personhood are not self-evident and are not obvious to everyone. This history of personhood goes back to ancient and medieval Christian theorizing and debating about personhood. It shows that concepts of personhood are not “self-evident” but rather are theoretical posits that are posited in theory construction in order to explain certain putative theological facts. Given that personhood is a theoretical posit and is not “self-evident,” moral philosophers who aim to determine the extent of the moral community on the basis of a supposedly “self-evident” concept of personhood are not justified in doing so. Moreover, given the Argument against Exclusive Personhood, philosophical theologians who wish to articulate models of the Trinity or Incarnation that are consistent with the seven ecumenical councils will find that they, like moral philosophers, are not justified to assume, or to insist on, modern personhood for their models of the Trinity or Incarnation. My overall conclusion, then, is that modern personhood is bad for ethics and unnecessary for conciliar ecumenical Christian theology. (shrink)

The practice of model-building is very common in analytic philosophical theology. Yet many other theologians worry that any attempt to model God must be hubristic and idolatrous. A better understanding of scientific modeling can set the stage for a more fruitful engagement between analytic theologians and their critics. I first present an account of scientific modeling that draws on recent work in the philosophy of science. I then apply that account to a prominent analytic model of the trinity, Michael (...) Rea and Jeffrey Brower’s “material constitution model.” I argue that modeling – whether scientific or theological – need not be understood as a hubristic enterprise. A model does not always try to grasp its target at all, let alone grasp it fully and completely. Even theologians who are committed to a strong doctrine of divine mystery can therefore find value in analytic modeling. (shrink)

The doctrine of the processions of the Son and the Holy Spirit from the Father, long an integral part of the trinitarian tradition, has recently been challenged by a number of philosophers and theologians, as is shown in the preceding article by Ryan Mullins.

This is followed by a consideration of the three principal objections to the doctrine developed by Mullins. (...) Next, there is a discussion of the difficulties for the doctrine of the Trinity if the doctrine of processions is rejected. Finally, I provide a positive account of the coherence and evidential support for the doctrine of processions. (shrink)

There are two general routes that Augustine suggests in De Trinitate, XV, 14-16, 23-25, for a psychological account of the Father's intellectual generation of the Word. Thomas Aquinas and Henry of Ghent, in their own ways, follow the first route; John Duns Scotus follows the second. Aquinas, Henry, and Scotus's psychological accounts entail different theological opinions. For example, Aquinas (but neither Henry nor Scotus) thinks that the Father needs the Word to know the divine essence. If we compare the theological (...) views entailed by their psychologies we find a trajectory from Aquinas, through Henry, and ending with Scotus. This theological trajectory falsifies a judgment that every Augustinian psychology of the divine persons amounts to a pre-Nicene functional Trinitarianism. This study makes clear how one's awareness of the theological views entailed by these psychologies enables one to assess more thoroughly psychological accounts of the identity and distinction of the divine persons.

A central figure in Victorian science, William Whewell held professorships in Mineralogy and Moral Philosophy at Trinity College, Cambridge, before becoming Master of the college in 1841. His mathematical textbooks, such as A Treatise on Dynamics, were instrumental in bringing French analytical methods into British science. This three-volume history, first published in 1837, is one of Whewell's most famous works. Taking the 'acute, but fruitless, essays of Greek philosophy' as a starting point, it provides a history of the physical (...) sciences that culminates with the mechanics, astronomy, and chemistry of 'modern times'. Volume 1 studies Greek physics and metaphysics, attributing their failure to a method that derived its principles from the common use of language. It surveys the state of the physical sciences in the middle ages, and deals with the rise of 'formal' astronomy - based on observation rather than calculation - as exemplified by Copernicus.

For decades now some Christian theologians, and some philosophers of religion, have labored at distinguishing Social Trinitarianism and non-Social Trinitarianism. Many have revised their models of the Trinity in light of counter-arguments or counter-evidence. For Christian theologians, or philosophers of religion, what counts as a good counter-argument or counter-evidence may (but need not) depend on respected theological authorities. Recently, some focus has been paid to what is called Conciliar Trinitarianism, which is the name for whatever is endorsed by, or (...) rejected by, the first seven ecumenical councils regarding the Trinity. For those who respect these ecumenical councils as authoritative (to some extent), it would be useful to get a clearer understanding of Conciliar Trinitarianism in order to assist in evaluating contemporary models of the Trinity. In what follows I argue that the Sixth Ecumenical Council (Constantinople III, in 680-681ce) made important contributions, and clarifications (for the contemporary reader), to Conciliar Trinitarianism. Surprisingly, there is no secondary literature regarding these contributions. So, the historical evidence given in this article is evidence that almost nobody has been aware of - apart from the editors of the critical edition of the Acts of Constantinople III. After having made the historical case, I discuss the implications of Constantinople III for (i) our understanding of the place of the Pseudo-Athanasian creed in Trinitarian speculation, (ii) standard narratives about the division between Greek and Latin Trinitarian theology, and (iii) contemporary models of the Trinity.

As one of the most influential thinkers in Christian history, St. Augustine (354–430) had a flair for teaching and meditated deeply on the mysteries of the human heart. This study examines a little-known side of his career: his work as a teacher of candidates for baptism. ln the revised edition of this seminal book, both the text and notes have been revised to better reflect the state of contemporary scholarship on Augustine, liturgical studies, and the catechumenate, both ancient and modern. (...) This edition also includes new findings from some of the recently discovered sermons of Augustine and incorporates new perspectives from recent research on early Christian biblical interpretation, debates on the Trinity, the evolution of the liturgy, and much more. This reconstruction of Augustine’s catechumenate provides fresh perspectives on the day-to-day life of the early church and on the vibrancy and eloquence of Augustine the preacher and teacher.

His mathematical textbooks, such as A Treatise on Dynamics, were instrumental in bringing French analytical methods into British science. This three-volume history, first published in 1837, is one of Whewell's most famous works. Taking the 'acute, but fruitless, essays of Greek philosophy' as a starting point, it provides a history of the physical (...) sciences that culminates with the mechanics, astronomy, and chemistry of 'modern times'. Volume 2 focuses on the rise and development of modern mechanics in the seventeenth century. Whewell shows how Galileo's laws of motion exemplify a paradigmatic shift from 'formal' to 'physical' sciences - a new approach concerned with explaining causes rather than merely observing phenomena. It also discusses the implications for physical astronomy of Newton's discoveries. (shrink)

Volume 3 first covers the mechanico-chemical sciences, emphasizing the convergence of mechanical and chemical theories in discoveries pertaining to electricity, magnetism and thermodynamics. A section on chemistry surveys Becher and Stahl's phlogiston theory, Lavoisier's theory of oxygen, and Faraday's laws of electromagnetic induction. The volume also covers mineralogy, botany, zoology, and anatomy. (shrink)
