In A Threat to Public Piety, Elizabeth DePalma Digeser reexamines the origins of the Great Persecution (AD 303–313), the last eruption of pagan violence against Christians before Constantine enforced the toleration of Christianity within the Empire. Challenging the widely accepted view that the persecution enacted by Emperor Diocletian was largely inevitable, she points out that in the forty years leading up to the Great Persecution Christians lived largely in peace with their fellow Roman citizens. Why, Digeser asks, did pagans and Christians, who had intermingled cordially and productively for decades, become so sharply divided by the turn of the century? Making use of evidence that has only recently been dated to this period, Digeser shows that a falling out between Neoplatonist philosophers, specifically Iamblichus and Porphyry, lit the spark that fueled the Great Persecution. In the aftermath of this falling out, a group of influential pagan priests and philosophers began writing and speaking against Christians, urging them to forsake Jesus-worship and to rejoin traditional cults while Porphyry used his access to Diocletian to advocate persecution of Christians on the grounds that they were a source of impurity and impiety within the empire. The first book to explore in depth the intellectual social milieu of the late third century, A Threat to Public Piety revises our understanding of the period by revealing the extent to which Platonist philosophers (Ammonius, Plotinus, Porphyry, and Iamblichus) and Christian theologians (Origen, Eusebius) came from a common educational tradition, often studying and teaching side by side in heterogeneous groups.

How is it that some conservative groups are viscerally antigovernment even while enjoying the benefits of government funding? In Piety and Public Funding historian Axel R. Schäfer offers a compelling answer to this question by chronicling how, in the first half century since World War II, conservative evangelical groups became increasingly adept at accommodating their hostility to the state with federal support. Though holding to the ideals of church-state separation, evangelicals gradually took advantage of expanded public funding opportunities for religious foreign aid, health care, education, and social welfare. This was especially the case during the Cold War, when groups such as the National Association of Evangelicals were at the forefront of battling communism at home and abroad. It was evident, too, in the Sunbelt, where the military-industrial complex grew exponentially after World War II and where the postwar right would achieve its earliest success. Contrary to evangelicals' own claims, liberal public policies were a boon for, not a threat to, their own institutions and values. The welfare state, forged during the New Deal and renewed by the Great Society, hastened—not hindered—the ascendancy of a conservative political movement that would, in turn, use its resurgence as leverage against the very system that helped create it. By showing that the liberal state's dependence on private and nonprofit social services made it vulnerable to assaults from the right, Piety and Public Funding brings a much needed historical perspective to a hotly debated contemporary issue: the efforts of both Republican and Democratic administrations to channel federal money to "faith-based" organizations. It suggests a major reevaluation of the religious right, which grew to dominate evangelicalism by exploiting institutional ties to the state while simultaneously brandishing a message of free enterprise and moral awakening.

In The Promise of Piety, Arsalan Khan examines the zealous commitment to a distinct form of face-to-face preaching (dawat) among Pakistani Tablighis, practitioners of the transnational Islamic piety movement the Tablighi Jamaat. This group says that Muslims have abandoned their religious duties for worldly pursuits, creating a state of moral chaos apparent in the breakdown of relationships in the family, nation, and global Islamic community. Tablighis insist that this dire situation can only be remedied by drawing Muslims back to Islam through dawat, which they regard as the sacred means for spreading Islamic virtue. In a country founded in the name of Muslim identity and where Islam is ubiquitous in public life, the Tablighi claim that Pakistani Muslims have abandoned Islam is particularly striking. The Promise of Piety shows how Tablighis constitute a distinct form of pious relationality in the ritual processes and everyday practices of dawat and how pious relationality serves as a basis for transforming domestic and public life. Khan explores both the promise and limits of the Tablighi project of creating an Islamic moral order that can transcend the political fragmentation and violence of life in postcolonial Pakistan.

From Greco-Roman Antiquity through to the European Enlightenment, philosophy and religious thought were inseparably interwoven. This was equally the case for the popular natural or ‘pagan’ religions of the ancient world as it was for the three pre-eminent ‘religions of the book’, namely Judaism, Christianity, and Islam. The lengthy and involved encounter of the Greek philosophical tradition – and especially of the Platonic, Aristotelian, and Neoplatonic strands of that tradition – initially with the Hellenistic cults and subsequently with the three Abrahamic religions, played a critical role in shaping the basic contours of Western intellectual history from Plato to Philo of Alexandria, Plotinus, Porphyry, Augustine, and Proclus; from Aristotle to al-Fārābī, Avicenna, al-Ġazālī, Aquinas and the medieval scholastics, and eventually to Meister Eckhart and Nicholas Cusanus and such modern philosophers and theologians as Richard Hooker, the Cambridge Platonists, Jacob Boehme, and G. W. F. Hegel to name but a few. The aim of the twenty-four essays comprising this volume is to explore the intellectual worlds of the three Abrahamic religious traditions, their respective approaches to scriptural hermeneutics, and their interaction over many centuries on the common ground of the inheritance of classical Greek philosophy. The shared goal of the contributors is to demonstrate the extent to which the three Abrahamic religions have created similar shared patterns of thought in dealing with crucial religious concepts such as the divine, creation, providence, laws both natural and revealed, such problems as the origin of evil and the possibility of salvation, as well as defining hermeneutics, that is to say the manner of interpreting their sacred writings.

The first volume of Michael Horton’s magisterial intellectual history of “spiritual but not religious” as a phenomenon in Western culture Discussions of the rapidly increasing number of people identifying as “spiritual but not religious” tend to focus on the past century. But the SBNR phenomenon and the values that underlie it may be older than Christianity itself. Michael Horton reveals that the hallmarks of modern spirituality—autonomy, individualism, utopianism, and more—have their foundations in Greek philosophical religion. Horton makes the case that the development of the shaman figure in the Axial Age—particularly its iteration among Orphists—represented a “divine self.” One must realize the divinity within the self to break free from physicality and become one with a panentheistic unity. Time and time again, this tradition of divinity hiding in nature has arisen as an alternative to monotheistic submission to a god who intervenes in creation. This first volume traces the development of a utopian view of the human individual: a divine soul longing to break free from all limits of body, history, and the social and natural world. When the second and third volumes are complete, students and scholars will consult The Divine Self as the authoritative guide to the “spiritual but not religious” tendency as a recurring theme in Western culture from antiquity to the present.

Philo of Alexandria and the Construction of Jewishness in Early Christian Writings investigates portrayals of the first-century philosopher and exegete Philo of Alexandria, in the writings of Clement of Alexandria, Origen, and Eusebius. It argues that early Christian invocations of Philo are best understood not as attempts simply to claim an illustrious Jew for the Christian fold, but as examples of ongoing efforts to define the continuities and distinctive features of Christian beliefs and practices in relation to those of the Jews. This study takes as its starting point the curious fact that none of the first three Christians to mention Philo refer to him unambiguously as a Jew. Clement, the first in the Christian tradition to openly cite Philo's works, refers to him twice as a Pythagorean. Origen, who mentions Philo by name only three times, makes far more frequent reference to him in the guise of an anonymous "one who came before us." Eusebius, who invokes Philo on many more occasions than does Clement or Origen, most often refers to Philo as a Hebrew. These epithets construct Philo as an alternative "near-other" to both Christians and Jews, through whom ideas and practices may be imported to the former from the latter, all the while establishing boundaries between the "Christian" and "Jewish" ways of life. The portraits of Philo offered by each author reveal ongoing processes of difference-making and difference-effacing that constituted not only the construction of the Jewish "other," but also the Christian "self."

Spiritual Taxonomies and Ritual Authority recounts how philosophers of the late third century C.E. organized the spirit world into hierarchies, positioning themselves as high priests in the process. By establishing themselves as experts on sacred matters, they fortified their authority, prestige, and reputation.
