Christian history is a diverse subject that can be approached in so many ways. This research guide approaches Christian history chronologically using three major epochs--early Christianity, medieval Christianity, and post-Reformation Christianity. (There are separate guides for the Reformation period and for American Christianity.) But Christian history can also be approached through the study of denominations and movements. specific regions of the world, and through the study of significant individuals within Christian history. These subject areas approach Christian history with a "macro" approach where we study history more wholistically. We can also use "micro" approaches where we explore congregational and organizational histories, though all "micro" histories exist within larger contexts. We can also study "historical theology," the study of how Christian theology has emerged over the history of the church and its many sub-movements.
Key to the study of Christian history is primary source evidence. While history is written with a narrative approach, the validity of those narratives is measured by the quality of evidence marshaled in support of the student's or researcher's conclusions. Students should understand the differences between primary, secondary, and tertiary sources.
