“A post-Christian society is not merely a society in which agnosticism or atheism is the prevailing fundamental belief. It is a society rooted in the history, culture, and practices of Christianity but in which the religious beliefs of Christianity have been either rejected or, worse, forgotten.”
– John O’Sullivan

North American churches are hemorrhaging people, losing donations and struggling to stay afloat – all are consequences of Post-Christianity. The postmodern earthquake caught pastors off guard. But now something even more destructive is coming – a Post-Christian Tsunami. This book provides a blueprint for creating churches that will not only survive, but actually thrive in a world that grows increasingly indifferent – even hostile – toward Christianity.

The Coming Post-Christian Tsunami Blog is a great resource for further study on Post-Christianity, leadership, church planting, and ministry.

I’ve spent a lot of time writing about churches that want to reach people in a post-Christian, post-modern world. I’m excited that Jon is bringing his voice to this critical subject. But Jon brings more than a voice: he brings real credibility. Having ministered in Europe, he’s seen the future. Drawing from more than a decade of experience reaching the unchurched in Europe, yet firmly planted again in America, Jon offers an insightful and compelling guide for North American church leaders. He provides practical application based on his own “been there and done it” experience from which leaders will greatly benefit.

Post-Christianity is taking its toll on churches and their leaders at an unprecedented rate. As a result many pastors are calling it quits and throwing in the towel. This reality needs to change. Jon’s book inspired out of years of experience as a church planter and church leadership coach in secular Europe, lays out a roadmap for building churches that engage the unchurched people groups with an emphasis towards younger generations. I believe this book can help churches of all sizes engage and encourage their members to be called into action and impact their communities for Christ.

I am so excited that Jon has been able to write out his church planting experiences in Europe to help churches in the changing cultural landscape in North America. This book provides very practical helps for church planters and church planting launch teams.
