Henry Edward Manning's The Temporal Mission of the Holy Ghost, or Reason and Revelation examines the role of the Holy Spirit in Christian faith. Manning emphasizes that the Holy Spirit has an active role in world history, not just in spiritual life. He is involved in human life and plays a role in the process of salvation. Manning argues that the Holy Spirit is not only a spiritual force, but also has a temporal mission in the world. The book explains the relationship between reason and revelation, and how the two work together to reveal truth about God and His plan for humanity. Manning also explores the role of the Church in mediating the mission of the Holy Spirit and how the Church can help people understand and live out their faith.
