This lively book not only unpacks the history of Christianity, but also explains how church history is created and organized. Different from traditional church history textbooks, the book: Has a global emphasis, rather than an exclusively Euro-American one; Explains the discipline of church history in addition to the content; Is readable, engaging, and inviting to new students; Makes church history accessible rather than stressing obscure dates and names. Conceptually, this book is revolutionary. The story of Christianity is never complete: it only expands. By allowing fresh players into the story, broadening our perspective to include women, the working class, heretics, and priests outside mainstream orthodoxy, we become open to new ways of understanding. And these new perspectives enhance our comprehension of the endlessly surprising story of Christianity's past.
