This book offers readers a new understanding of the methods of religious instruction and the uses of religious texts in Anglo-Saxon England, capturing the lived significance of these texts to contemporary audiences. An examination of Anglo-Saxon texts based on their didactic strategies, succeed at teaching theology, and blended cultural influences allows us to evaluate both celebrated and neglected texts more even-handedly and in a new light. The book first deals with the history and character of the theology of Christ's Ascension. It traces the history of Ascension theology from its scriptural roots to its patristic elaborations and to its transmission in Anglo-Saxon England, presenting those doctrines and themes that become most relevant to insular authors. The history of Ascension theology shows that Anglo-Saxon authors make deliberate and innovative choices in how they present the inherited patristic theology to their contemporary audiences. The book then contends that both the martyrologist and the Blickling homilist recognize the importance of liminality to Ascension theology and use the footprints as the perfect vehicle to convey this. It also examines the ways in which Anglo-Saxon authors construct spatial relationships to establish symbolic relationships between three major Christological events: the Ascension, the Harrowing of Hell, and Christ's Entry into heaven. Analysing individual Rogationtide and Ascension homilies, both Latin and vernacular, the book moves from the formal preaching of theology to the spatial practices of Rogationtide liturgy to the popular beliefs about boundaries and the earth.
