Ascetic Pneumatology from John Cassian to Gregory the Great presents three interconnected arguments. The first argument concerns scholarly readings of antiquity: there are developments in 5th and 6th century Latin pneumatology which we have overlooked. Theologians like John Cassian and Gregory the Great were engaged in a significant discussion of how the Holy Spirit works within Christian ascetics to reform their inner lives. Other theologians, like Leo the Great, participate to a lesser extent in a similar project. They applied pneumatology to theological anthropology. Thomas L. Humphries, Jr. labels that development "ascetic pneumatology," and beings to track some of the late antique schools of thought about the Holy Spirit. The second argument concerns the reception of Augustine in the two centuries immediately after his death: different people read Augustine differently. Augustine's theology was known and understood to varying degrees in various regions. Humphries demonstrates significant engagements with Augustine's theology as it was relevant to Pelagianism (evidenced in Prosper of Aquitaine), as it was relevant to Gallic Arians (evidenced with the Lérinian theologians), and as it was relevant to African Arians and certain questions posed of Nestorianism (evidenced with Fulgentius of Ruspe). Instead of attempting to rank various theologians as better and worse "Augustinians," Humphries argues that there were different kinds of "Augustinianisms" even in the years immediately after Augustine. The third argument concerns Gregory the Great and his sources. Once we see that ascetic pneumatology was a strain of thought in this era and see that there are different kinds of Augustinianisms, we can see that Gregory depends on both Augustine and Cassian. In the closing chapters, Humphries argues that Gregory uses Cassian's ascetic pneumatology, and this allows Gregory's synthesis of Cassian and Augustine to stand in greater relief than it has before. The study begins with Cassian, ends with Gregory, and is attentive to Augustine throughout.

This is a study of how Christians understood the Holy Spirit in the 5th and 6th centuries. Humphries argues that we can see various schools of thought within Christianity in this period but that many of them are occupied with similar questions about how to understand human life and how to understand divine life.

Sites of the Ascetic Self reconsiders contemporary debates about ethics and subjectivity in an extended engagement with the works of John Cassian (ca. 360–ca. 435), whose stories of extreme asceticism and transformative religious experience by desert elders helped to establish Christian monastic forms of life. Cassian’s late ancient texts, written in the context of social, cultural, political, doctrinal, and environmental change, contribute to an ethics for fractured selves in uncertain times. In response to this environment, Cassian’s practical asceticism provides a uniquely frank picture of human struggle in a world of contingency while also affirming human agency in ways that signaled a challenge to followers of his contemporary, Augustine of Hippo. Niki Kasumi Clements brings these historical and textual analyses of Cassian’s monastic works into conversation with contemporary debates at the intersection of the philosophy of religion and queer and feminist theories. Rather than focusing on interiority and renunciation of self, as scholars such as Michel Foucault read Cassian, Clements analyzes Cassian’s texts by foregrounding practices of the body, the emotions, and the community. By focusing on lived experience in the practical ethics of Cassian, Clements demonstrates the importance of analyzing constructions of ethics in terms of cultivation alongside critical constructions of power. By challenging modern assumptions about Cassian’s asceticism, Sites of the Ascetic Self contributes to questions of ethics, subjectivity, and agency in the study of religion today.

Oliver B. Langworthy examines the interaction of soteriology and pneumatology in Gregory of Nazianzus' thought. He shows that this interaction, Gregory's soteriological pneumatology, is a coherent, significant, but under-examined area of Gregory's thought. His study engages in a chronological treatment of a wide range of Gregory's prose and poetic works. This allows for the particular character of Gregory's soteriological pneumatology to emerge, notably his emphasis on the experience of the Spirit. The result is a more complete and nuanced picture of Gregory's theological investment in a divine and "truly holy" Spirit that is operative in the salvation of the believer.

The contributors to Grace for Grace focus on the debates on grace and free will inspired by Augustine's later teachings on grace and the various reactions to it. Based on fresh study of a wealth of primary sources, this international team of scholars explores the intra-Church debates over grace and free will after Augustine and Pelagius. In both popular and scholarly literature, the conflict has been traditionally referred to as the "Semi-Pelagian Controversy". For several decades, however, scholars have been distancing themselves from that simplistic and inaccurate portrayal. This book intends to solidify a disparate movement of scholarly thought and provide a secure basis for renewed study of the persons, texts, and events of a critical period in the reception of Augustine in the Early Middle Ages.
