SEISMOS: Christian Citizenship in a Post-Christian West

Citizenship — the relationship between the people and the powers — is dramatically changing for Christians in the West. Secularism has initiated a 'cultural climate change' with profound consequences for religion generally, and Christianity specifically.

Reviews

Dr James Orr, Associate Professor of Philosophy of Religion, University of Cambridge
Landrum has produced a masterful analysis of Christianity's evolving place in Western culture that is as sobering as it is inspiring. Elegantly mapping out the challenges confronting Christian citizenship while offering practical wisdom for faithful resistance and cultural renewal, this is an essential handbook for believers seeking to navigate our present moment with biblical wisdom, strategic insight, and the hope at the heart of the Gospel. A timely and prophetic work that promises to help shape Christian public leadership for many years to come.

Rod Dreher, author: The Benedict Option (2017), Live Not By Lies (2020), Living in Wonder (2024)
The hour is late: Landrum's urgently important book is the electrifying jolt that Christians of the West need to awaken from our complacent slumber, and take up effective resistance - while there is still time.

Lord Alton of Liverpool, Professor of Citizenship, Liverpool John Moores University
Cultural climate change is real. Read this book.

Paul Coleman, Executive Director, ADF International
A passionate and thought-provoking call to action to a church half-asleep. Essential reading for any who wish to 'understand the times, and know what to do' (1 Chron 12:32).

Dr Jenny M Taylor, Associate Fellow in Journalism, Kirby Laing Centre for Public Theology
It is tragic that this book had to be written. That it has been written is indicative of the unique integrity, insight, fury, and intelligence of its author. Dr Landrum lays out the problems of our self-destructing civilization with extraordinary, sometimes frightening acuity, and then shows us how to get involved to arrest it.

Revd. Dr Ian Paul, Adjunct Professor, Fuller Theological Seminary
There has been a seismic change in Western culture over the last 30 years, and as that change has accelerated, it has become more antagonistic to the Christian faith. This book offers a vital guide to navigating our way across the stormy seas, confident in the grace and provision of God.

David Robertson, author and broadcaster
The highest commendation I could make for this book is simply that, as someone who has been engaged in cultural observation and practice for the past four decades, I wish I had written it!

Tim Dieppe, Head of Public Policy, Christian Concern. Author of: The Challenge of Islam (2025)
This book is the ideal combination of theology, politics, and practical ideas. All Christian leaders will find his insights and perspective helpful in navigating a rapidly changing culture and thinking through their own responses to these changes.
