The paper considers three possible definitions of what it is for an action to be ‘morally’ good: (1) that it is overall important to do; (2) that it is overall important to do in virtue of a universalisable principle; and (3) that it is overall important to do in virtue of a universalisable principle, belonging to a system of such principles, which includes almost all of certain moral fixed points. I defend (3) and show how we can reach such a system, starting from the basic beliefs with which we find ourselves, through the process of reflective equilibrium. Moral realism is then the doctrine that there is such a system of true moral beliefs. My optimistic view is that all human communities could eventually reach the same such system. But, if they cannot, then there will be two (or more) different such systems, and so two (or more) different senses of ‘moral realism’.

The nature and value of the religious priesthood have often been questioned, including after Vatican II. John Paul II, however, claims that the religious priest ‘reproduces in his life the fullness of the mystery of Christ’. Examining Aquinas’s understanding of Christ’s total self-sacrifice provides a model that explains how. In this article, I present a Christological and Thomistic approach to the question by identifying Christ as a religious priest, highlighting one of Aquinas’s patristic sources (St Gregory the Great) and one of his greatest spiritual interpreters of modern times (Bl Columba Marmion). Because of his grace of headship, Christ contains all the perfections found in his members. The perfection of Christ’s priestly and religious life consists in his total sacrifice of himself to the Father out of love. Christ firmly fixed his will to offer himself from the moment of the Incarnation. By vowing to follow the counsels, religious priests imitate the fixity of Christ’s will to offer himself as a total self-holocaust. This conclusion allows me to propose that Christ is the religious priest, which has several theological and pastoral implications.

Catholic social thought and teaching is sometimes conceptualised using an historical or principles-based approach. This paper proposes an alternative framing, construing Catholic social teaching (CST) as a multi-layered phenomenon that can be grouped into three broad tiers, each with a distinctive role. This framing is not intended to supercede the others, nor is it inconsistent with them. The proposal emerges out of a series of discussions hosted by the Catholic Agency for Overseas Development, a Catholic UK-based development agency, member of Caritas Internationalis, and an official agency of the Bishops’ Conference of England and Wales. The paper operates on two levels simultaneously: it attempts a distinctive reframing of CST using a distinctive source, and it attempts an enactment of CST methodologically and structurally. Construing CST as a multi-layered phenomenon that can be grouped into three broad tiers provides a clarity that empowers us in two ways. First, it clarifies the distinctive role of CST at each level. Second, it makes clear that CST is a work of the Spirit rather than a human phenomenon. Such an understanding of CST brings out with particular clarity a vision of the role, purpose, and even the agency of Catholic social thought in relation to a troubled world.

This paper examines, from a Thomistic perspective, the possible consequences of the twentieth-century reform of the ‘Kyrie eleison’ from ninefold set of invocations to a sixfold call-and-response structure. First, we present Aquinas’s distinctly Trinitarian exegesis of the ‘Kyrie’ in light of the history of troped liturgical texts. Next, we will account for the historical diversity of the troped ‘Kyrie’ genre while emphasizing importance of the Trinitarian elements. The third section recounts recent work on Aquinas’s theory of the passions and their effects of language formation; this leads to the fourth section, which casts a philosophical eye on the role of melisma in the liturgy. To conclude this study, we suggest the restoration of some troped ‘Kyrie’ texts in the Roman Rite.

This paper argues that being there, actually existing, is a notion that cannot be explicated by formal logicians, cannot be defined in terms of conscious perception, and cannot be satisfactorily explained using the theories of mathematics or natural science. So, must we turn to theology to make up for the deficiencies of the methods so far canvassed? The paper concludes by considering the Thomistic identification of God with existence itself, but argues that it would be a mistake to suppose that the mystery of actual existence is thereby dispelled.

Broadly drawing on the writings of Thomas Aquinas, this article is a systematic-theological (rather than historical-theological) engagement with the theme of providence and divine causality. It aims to dispel some modern misunderstandings of these topics by highlighting how pre-modern approaches differ from today's perspective. It does so by arguing, firstly, that Thomas, given his teleological focus, construes divine causality not so much as efficient causality but rather in terms of final causality. I will also make the point that Thomas's calling God a ‘universal cause’ should not be construed in terms of omni-causality, as if God predetermines every event (be it necessarily or contingently). In the final part of this contribution, I make some observations on the arbitrariness of afflictions and the connection with the gratuitousness of charity within the providential ordering.

Why celebrate Thomas Aquinas? Three eras that celebrated Aquinas in unique ways—the Fourteenth century that canonized him, the Sixteenth century that declared him a doctor of the Church, and the nineteenth century that made him patron of the schools—all struggled with the corrosive effects of nominalism and voluntarism on Western culture. With the help of G. K. Chesterton and C. S. Lewis, this essay suggests that these eras were drawn to Aquinas because his theology offers an antidote against these twin diseases. Specifically, Thomas Aquinas's theology can help us confront the ills of nominalism and voluntarism by encouraging us to celebrate nature, grace, and Christian apprenticeship in virtue as the perennial gifts of God's love.

The topic of wisdom attracted much less attention in modern thought than in ancient and medieval times. However, there has been a renewal of interest in it in recent psychology and philosophy, and a variety of questions has emerged from this current work. Aquinas has a detailed and elaborate account of the wisdom which pervades his oeuvre. This paper explores that and seeks to answer some of these contemporary questions from Aquinas's perspective.

The idea of ‘connatural knowledge’ is attributed to Aquinas on the basis of passages in which he distinguishes between scientific and affective experiential knowledge of religious and moral truths. In a series of encyclicals beginning with Leo XIII's Aeterni Patris, popes have celebrated and commended Aquinas as the supreme guide in philosophy and theology and in some of these cited his discovery of connatural knowledge. The course and context of his ‘elevation’ are explored before proceeding to a discussion of moral knowledge in which different forms of non-theoretical cognition are identified. This leads to an examination of work by Elizabeth Anscombe on the factuality of ethical judgement and connaturality. Aquinas and Anscombe offer important insights but more work remains to be done. Moral knowledge is a many-faceted thing. More accurately, it is not one thing but many things analogously related both by their modes and by their objects.

Aquinas's views about the morality of lying are well known and often discussed by commentators. But his views about the nature of lying have yet to receive the attention they deserve. In this article, I take some of the first steps necessary to correct this state of affairs by clarifying and offering a limited defense of the account of lying that Aquinas presents in in his Summa Theologiae—more specifically, in that portion of it known as the treatise on truth (Part 2-2, Questions 109–113).

‘Synod’ and ‘synodality’ have become synonymous with Pope Francis. Since Pope Paul VI instituted the Synod of Bishops as a permanent office in 1965, there hasn't been any pontificate that has given these matters as much profile and attention as his has. Why is this the case, and what is Pope Francis’ vision for a synodal Church? More fundamentally, what is synodality, according to tradition of the Church, and Pope Francis? Several years into both local and global synodal-type processes and formation gatherings, it seems many people, even prominent Church leaders, readily admit that they still do not fully understand it. For this reason, this article sets out to provide a general overview and introduction.

This paper looks first at the scope of religious experience, offering some representative examples of phenomena that typically give rise to spiritual experiences. This leads on a consideration of the phenomenology of such experiences – the particular way in which they present themselves to the conscious subject. Lastly, the paper tackles the vexed question of the source of such experiences, and suggests that this is best understood in terms of a (certain kind of) theistic framework.

In this paper I will investigate a recent development on St Thomas Aquinas’ definition of dual causality and see if it truly develops Aquinas’ thinking or departs from it. Denis Edwards made significant contributions to contemporary Catholic theology especially as it concerns the relationship between science and Christian theology. In one very interesting publication, ‘Toward a Theology of Divine Action’, Edwards employs the developments of William R Stoeger, a Jesuit theologian who has also contributed a great deal to Catholic thought on science, to reconcile Stoeger's work with the Thomist tradition. Edwards argued that Stoeger's account of the laws of nature creates a space for the development which is built on Aquinas’ account of divine causality and miracles. However, I hope to show that Edwards’ account of divine causality does not actually offer anything new and opposes key features of Thomist thought. This paper will investigate Edward's understanding of the Thomist position and the consequences of departing from it.

While the story of Thomas Aquinas and Bonaventure of Bagnoregio engaging in a friendly contest, at the behest of Pope Urban IV, to compose the Mass and Office of Corpus Christi is likely a pious fiction, one can still ponder the fascinating hypothetical scenario: had such a contest taken place, who might have won? To consider that question, this paper embarks on a close reading of Bonaventure's hymns in his Office of the Passion, comparing his poetic approaches to those of Aquinas in the hymns for Corpus Christi. After an introductory historical examination into the supposed involvement of both friars in the composition of the Corpus Christi liturgy, this article proceeds in three sections. First, a look into select excerpts from Bonaventure's Office of the Passion will establish his general poetic technique. In the transitional second section, a direct comparison between Bonaventure and Aquinas on the composition of the final doxological verses of their respective hymns will place their different poetic styles into greater relief. Third, a broader reading of Aquinas's Eucharistic hymns will highlight the unique qualities of his versified praises. Finally, in light of the foregoing analyses, a prospective winner of the hypothetical contest will be suggested.
