The questions of Christianity are perennial. How are Judaism and Christianity related? Are Jesus and the Holy Spirit God? Is the end of the world imminent? How should we relate faith and reason? In this innovative work, Derek Cooper tells the story of Christian history by presenting the twenty questions (one for each century!) that shaped the Christian church throughout the world. The result is a book that narrates the exciting history of Christianity from a global perspective by means of simple questions and concerns that face the church today.
