This chapter illuminates the relatively neglected global aspect of American Christianity and broadens the framework in which one customarily thinks about the successes, failures, and variations among faith communities. The central need is to reorient perspective in such a way that the chronology of religious events in particular national locations is understood in a wider, more diverse, and interconnected cultural context. As globalization increases, that task becomes ever more urgent. The globalization of American Christianity poses significant questions about the changing role of Christianity within the United States itself. One of these is whether being part of a church makes any difference to the way Christians think about America's role in the world, particularly on questions of international policy. An aspect of globalization that has become trite, because it is so often mentioned, is the fact that international transportation and communication have become quicker and easier.
