The desire for sexual intimacy reflects the divine image in which human beings are made. This deep yearning for communion resides in both the erotic urge for intimacy and the soul's longing for God. The erotic character of Christian faith and spiritual practice shapes nearly every chapter of Christian history as well as the biblical witness to God's passionate desire to be in communion with God's own creation. Yet few Christians read either the Bible or Christian history through that erotic lens. Before Christian communities try to address sexual ethics, the more fundamental theological question demands attention: What can sexual intimacy tell us about God? This book invites reflection on sexual relationships within a broad theological framework marked by creation, fall, and redemption. These classical hallmarks of Christian faith are proclaimed and enacted at every liturgical celebration of the Eucharist, which offers a compelling way to engage the link between sexual intimacy and the longing for God, or the hoped-for promise of "divine communion."
