Abstract: In this essay I review three important volumes for the field of secular studies: Varieties of Secularism in a Secular Age, Rethinking Secularism, and The Power of Religion in the Public Sphere. All three volumes explore the nature of the secular and the status, role, and possible futures of religion in our late modern, globalized world. The volumes present 34 essays by 30 authors representing seven disciplines, and at least six end games. For some, questions of religion-secular entanglement are a historical matter and the task is to map intellectual and ideological trajectories. A second purpose is to empirically document the complexities of particular religion-secular entanglements in particular socio-cultural locations. For others, the remit is theoretical, to discern a conceptual agenda for the ongoing study of religion-secular entanglements. Others are more philosophical, chasing the existential consequences of secularity. A fifth end game is applied in nature: reflections on how political actors might best engage the religious and the secular in acts of governance and international relations. Finally, there are normative voices, those seeking to name what a good, productive religion-secular entanglement ought to look like. Taken together, the volumes mark a thriving, mature field of scholarly inquiry: secular studies has come of age.
