Friedrich Schweitzer 
Postmodern Life Cycle [PDF ebook] 

Schweitzer’s goal in this book is to explore what postmodernity actually means for theology and how theology and the church may respond to its challenges. He focuses on the life cycle as it is changing with the advent of postmodernity, looking sequentially at segments of the life cycle using different lenses: modernity, postmodernity, and responses from church and theology. Schweitzer concludes with a theology of the life cycle.
