The authors presented in this volume deal with important cases of Protestantization of religion or of debates on religion. One chapter deals with Protestant formatting of contemporary Islam, another discusses how Pentecostal Protestantism has an important role in formatting religion outside Europe today. Two of the authors analyse contemporary debates on circumcision and investigate how Protestant preconceptions influence these debates. Finally, several authors deal with the complex question of how Protestant religion is related to modern Secularity: either as a point of departure for “non-religion”, or as a point of departure for a Protestant understanding of secularity.
