A thousand years ago, the church experienced a time of tremendous upheaval called the Great Schism. The one faith became two churches, East and West, and the course of world history was forever changed. And it all swirled around one Latin word in the Nicene Creed, filioque, that indicated the Holy Spirit proceeded both from God the Father "and from the Son." From the time that phrase was officially instituted onward, the Holy Spirit's place in the Trinity and role in the lives of believers would be fiercely debated, with ramifications being felt through the centuries to this very day.

In this fascinating book, readers will encounter not just the interesting historical realities that have shaped our faith today but also the present resurgence of interest in the Holy Spirit seen in many churches across the theological spectrum. Tickle and Sweeney make accessible and relevant the forces behind the current upheaval in the church, taking readers by the hand and leading them confidently into the Age of the Spirit
