Angels have fascinated people for millennia because they point to an invisible dimension that parallels our own. This book examines the different ways that angels have been portrayed at certain key points in biblical and theological history. By tracing patterns in the appearance of higher-order beings from their ancient Near Eastern origins, the Hebrew Scriptures, the writings of Pseudo-Dionysius, Thomas Aquinas, Karl Barth, and even modern, New Age writers, Angelology demonstrates that angels allow various authors to emphasize divine transcendence, immanence, and creativity. Identifying the theological purpose underlying the depiction of angels at certain key points in the history of their use raises new questions about how angels are to be understood by people today.
