In this monograph, Rick Wadholm, Jr provides the most comprehensive study of the role of the Spirit in the Former Prophets to date. Beginning with a thematic survey of previous scholarship on this topic, the author then offers a Pentecostal reading strategy by which this portion of the biblical canon is assessed. Drawing on the reception history of the pneumatological texts found in the Former Prophets in early Pentecostal periodical literature, Wadholm traces their impact on these early readers and the implications of their interpretations for contemporary Pentecostal interpreters. This survey, then, is followed by a careful reading of the relevant Former Prophet passages, utilizing a literary and theological narrative approach that allows the voice of the text to be heard on its own terms. Building on the fresh insights produced by the foregoing analyses, Wadholm offers a constructive Pentecostal theology of the Spirit informed by the Latter Prophets in conversation with contemporary Pentecostal and other relevant pneumatological scholarship.
