Open our eyes
Format: Paperback
I recently finished reading Joash's very insightful, inspirational, and encouraging book. I hope it is read and implemented far and wide. His interpretation of Jesus and "the church" is as close to the spirit of Scripture as I can find. Twenty years ago, I read "Jesus and the Disinherited" by Howard Thurman that led me to places and situations and cultures and events which were not part of my own life's context. It was Jesus' context and I began to understand his lessons through his eyes instead of my own. Joash, like Howard Thurman, is right - we colonized, Caucasian, Western civilization folks just don't get it. But we should and we need to. Open your mind to read this book and see things through God's eyes. Thank you Joash!! We should all look for ways to extend this teaching to others. "...thy will be done, on Earth [all of earth and humanity] as it is [and will be] in Heaven.

A Bold, Pastoral Call to Decolonize the Gospel
Format: Paperback, Format: Paperback
When I began my journey of theological deconstruction, I quickly realized that shedding the harmful elements of conservative white evangelicalism wasn’t enough. The deeper I went, the more I saw how white Christianity remains entangled with colonial narratives that uphold social and sexual hierarchies and distort the liberating truth of the Gospel.
Rev. Joash Thomas’s *The Justice of Jesus* is the book I didn’t know I needed. His voice has profoundly shaped my theological imagination, and this work is a masterclass in liberation ecclesial theology. With clarity and courage, he names the perversion of white, colonialist, slaveholder theology and invites readers to confront its lingering presence in our churches, our pulpits, and our lives.
What sets this book apart is its balance of prophetic fire and pastoral tenderness. Rev. Joash never veers into cynicism or outrage for outrage’s sake. Instead, he offers practical, Spirit-led guidance for reclaiming the Gospel from the sin of colonialism and whiteness. He casts a vision of Eucharistic unity, a table wide enough to defy empire and deep enough to hold our collective liberation in Christ.
This book emboldened me to use my voice and privilege to pursue the decolonization of theological practice in my own context. I cannot recommend it highly enough to anyone seeking a Gospel that liberates, heals, and restores.

Un libro necesario para la iglesia hoy
Format: Paperback, Format: Paperback
As a believer from the Global South. As a child who first heard the liberating message of Jesus through integral mission in Latin America. Yet, over the years, I was also exposed to a highly colonized version of the gospel—one that increasingly abandoned the most vulnerable and aligned itself with a form of Christianity distant from real human needs. Reading this book restores my hope, not because change will come quickly or easily, but because it opens the space for the necessary conversations of reevaluation.
Joash, in a very direct way, lays out the causes and effects of inherently unjust colonizing systems that have broken entire societies, and shows how these systems have permeated the way we live out the gospel of Jesus. By bringing these to light in various areas, he challenges the Western church to reconsider its practices, to move alongside the oppressed, and to become aware of its own shortcomings. At the same time, he reminds us that hope remains, that we have much to learn from the Global South, and that there are many silenced voices that must urgently be heard.

Generous, inclusive, and deeply Christian.
Format: Paperback
What an amazing book this is! Joash Thomas challenges western Christians to sit in dialogue with global south brothers and sisters, and to be willing to learn from them. If justice means everyone having what God wants them to have, then why is justice not a priority for so many of us? Never scolding, and never despairing, Joash walks us through the lessons we could take away from such a meeting, and offers actual strategies for incorporating "justice work" into the lives of western churches. A MUST READ!
