Background

Carcinoembryonic Antigen-related Cell Adhesion Molecule 3 (CEACAM-3), or CD66d, is part of the CEA protein family consisting of CEACAMs and the pregnancy-specific glycoproteins (PSGs). Both CEACAM and PSG molecules have been identified in humans and belong to the much larger glycosylphosphatidylinositol (GPI)-linked immunoglobulin (Ig) superfamily. Human CEACAM-3 is ~35 kDa, consisting of an extracellular domain (ECD) containing one IgV-like domain, a single transmembrane domain and a cytoplasmic tail. CEACAM family members are widely expressed in epithelial, endothelial, and hematopoietic cells, including neutrophils, T-cells, and NK cells. CEACAMs appear to be capable of transmitting signals that result in a variety of effects depending on the tissue, including tumor suppression, tumor promotion, angiogenesis, neutrophil activation, lymphocyte activation, regulation of the cell cycle, and regulation of adhesion. CEACAMs have now been associated with numerous intracellular signaling processes including cell adhesion, cell growth, recognition and differentiation, angiogenesis, and apoptosis. CD66d antibody increases neutrophil adhesion to the monolayer of human umbilical vein endothelial cells.

Thoughtful, Challenging, Research-Based, and Compelling: Joash P. Thomas' "The Justice of Jesus"
Format: Paperback
I cannot recommend this book enough! Especially for Christian's actively involved in a church community. In The Justice of Jesus, Joash offers a compelling and challenging vision of what authentic, Christ-centered justice truly looks like. What I loved most about this book is how directly Joash engages with the reader to reflect on what justice means, what it looks like, and why that can sometimes be an uncomfortable topic, especially for White, Western Christians like myself; and Joash masterfully addresses the topic in a way that's sensitive yet direct and firm, allowing readers from all backgrounds to thoughtfully consider his argument without feeling targeted or turned off. I also really appreciate the quality of his evidence and argument, especially as it relates to anecdotal experience. He provides countless examples of Church communities engaged in the work of justice Jesus' way. There is so much I wish I could dive deeper into, but one of the key takeaways from this book that I appreciate is that, as hard and uncomfortable it can be to acknowledge, Christian's in the West (especially white) are deeply privileged and carry with them a colonized theology that's more often led to harm, oppression, and violence than it has to love, peace, and brotherhood. We've over emphasized the salvation of souls to the detriment of care for physical bodies, perfectly content to keep people in bondage so long as they say some magic words or profess belief. Joash rightly challenges this, calling on Western Christian's to 1) acknowledge their privilege and history of colonial conquest, 2) hold freedom of the body just as highly as salvation of the soul, 3) prioritize unity as beloved children of God over theological/liturgical differences, and 4) do the hard work necessary to address the harm our past has done (a task for which Joash provides many examples/suggestions) as we move forward as the Body of our Lord. Joash includes thoughtful reflection questions at the end of each chapter, making this the perfect book for a book group or study. I recommended it to the pastor of my church and look forward to engaging with it even more!

Worthwhile read.
Format: Kindle
The first few chapters would perhaps been worth 10 stars the remaining chapters not so much although it was good information. It became a bit monotonous but all in all it’s still a five star book.

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.
