All three Synoptic Gospels tell the story of Jesus's transfiguration. Yet there has been surprisingly little written about this key event, and many readers struggle to understand its significance and place in redemptive history, let alone how it might be applied. Here, Patrick Schreiner provides a clear and accessible study of the transfiguration with an eye toward its theological significance and practical application. Namely, this event points to Jesus's double sonship, revealing the preexistent glory of the eternal Son and the future glory of the suffering Messianic Son. Further, the transfiguration points to Christians' own formation and transfiguration. Schreiner traces the transfiguration theme through Scripture and employs hermeneutical, trinitarian, and christological categories to assist his exegesis, thus challenging modern readings. This enlightening study will be of interest to students, pastors, and serious lay readers.
