This article explores three historical components of Pentecostal theology that influenced Pentecostal missionary women by examining missions after the Pentecostal revival of the early twentieth century. This article presents four case studies of such Pentecostals and their responses to Pentecostal experiences and missionary careers for ongoing theological consideration about what it means to 'Go into all the world' as a Pentecostal.
