The Holy Spirit who worked on the first Christian Pentecost continues to work in the church and the world today. This being so, the field of pneumatology—the theology of the Holy Spirit—should pique the interest of both the "average" Christian and the academic theologian, perhaps more than it has in recent times. This collection of chapters brings pneumatology into conversation with a wide variety of disciplines, including scripture, patristic and medieval theology, and history. The result is a scholarly monograph that enriches both pneumatology and the fields with which each contributor engages. Furthermore, with its attention on the work of the Spirit in the sacraments and the life of the church, Pneumatology at the Beginning of the Third Millennium will help pastors and catechists in their ministries to understand more deeply the riches of the theology of the Third Person of the Trinity.
