"If only we were a Christian country again!" Christians, particularly those in the West, often lament their loss of influence in modern politics and culture. It seems that everywhere one turns, Christendom in the West is dealt another blow, with Christian reactions ranging from withdrawal and entrenchment, to cries of persecution and talks of organized resistance. Pentecostalism, Secularism, and Post Christendom seeks to address these concerns via an examination of Classical North American Pentecostalism as it wrestles with the very real challenges posed by the increasing post-Christian ethos of Western culture. In addition to providing a number of concrete steps, Pentecostals may take in their efforts to better understand and connect with modern culture, this work will argue that counter-intuitively, the death of Christendom (if properly addressed), may in fact herald the arrival of the Church's finest hour.
