Pentecostalism is the great religious story of the twentieth century. (P. 217)Many scholars trace the origins of Pentecostalism to early 20th Century Los Angeles (pp. 81-84), but its reach is now global. It is particularly successful in Latin America where it is challenging the long-standing religious monopoly of the Roman Catholic Church (p. 215).
The success of Pentecostalism is a strange mixture of unflinching belief and pragmatism, raw emotion and self-improvement, improvisation and organization: it is as if somebody had distilled American-style religion down to its basic elements and the set about marketing it globally. (P. 218).
The authors identify many reasons for Pentecostalism's success, and you should review what those are. One of those may be surprising to you:
Indeed, one of the things that attracts people around the world to Pentecostalism is its very Americanness. (p. 219)If that is true, it would not be the first time that a highly influential nation or empire helped cause the spread, either deliberately or inadvertently, of a particular religious group. The existence of the Roman Empire helped Christianity spread, for example. In fact, you could ask if there has ever been a case of a religious group going global that did not have behind it some helpful connection to an influential nation.
