Churches have been repenting, apologizing, and asking forgiveness for beliefs and practices they once justified. These often high-profile statements raise questions such as: Can a church repent for things that happened centuries ago? Is it possible for a church to sin or to be forgiven? What difference will repenting make? Is this just more church hypocrisy? In this book Jeremy Bergen tells the story of ecclesial repentance in recent decades and explores the theological issues its raises. He argues that because it is grounded in the doctrines of Christ and the Holy Spirit, ecclesial repentance requires the church to articulate in new ways its own nature and mission.
