The church has been under attack from its inception, but certain struggles seemed to threaten its very existence. In this inspiring book, Dr Matthew Knell celebrates some of these key figures who have kept the church alive in the midst of great adversity, exploring three major periods of persecution from the early church to the present day. This fascinating journey begins with Irenaeus of Lyon, who battled courageously against the theological threat of Gnosticism, followed by Basil of Caesarea, who defended the church from attacks on its spirituality. The book concludes with the modern Chinese church, many members of which have been attacked and even martyred for their faith. Using the examples of these defenders and many others, Dr Knell inspires readers to stand firm in the face of adversity as the global church continues to experience persecution.
