The movement that was known as the New Order of the Latter Rain is one of the few elements of the twentieth century Pentecostal revival for which Canada, for better or worse, must accept primary responsibility. Not only did the movement begin in Canada, but in Western Canada specifically. Therefore, a consideration and review of its nature and effects is particularly relevant on this occasion of the convening of the Pentecostal World Conference on Canada's west coast. In this paper we will first review some of the historical backgrounds of the movement, and then we will make an attempt to understand it and evaluate its influence upon the thinking and practices of Pentecostal Christians. In the matter of terminology, the expressions "New Order," and "Latter Rain," as well as "New Order of the Latter Rain" were variously applied by the movement to itself in its formative years. Today's writers from within the movement's ranks now use terms such as "the move," or "the Move of the Spirit," or "the move of 1948." In this paper we will use the older terms.
