Religion is supposed to offer safety, meaning, and belonging.But what happens when faith trains the nervous system to live in fear?Religious Trauma in a Nutshell: When Faith Becomes a Threat to the Nervous System is a clear, uncompromising exploration of how religious systems can become sources of chronic threat rather than support-and why the effects persist long after belief fades.This book does not argue theology, attack religion, or reduce complex experiences to slogans. Instead, it examines mechanisms: how fear conditioning, shame, authority, and attachment shape the nervous system; why leaving religion can feel neurologically dangerous; and why symptoms are so often misdiagnosed as anxiety, depression, or personal weakness.Written with depth, precision, and clinical clarity, this book reframes religious trauma as an embodied survival adaptation, not a failure of faith or character. It explains why spiritual language can become triggering, why the body may feel unsafe without God, and what healing actually looks like when meaning itself was used as a tool of control.You will discover: How religious belief enters the nervous system through attachment and authorityWhy fear, sin, hell, and purity function as long-term threat architecturesHow shame, dissociation, and "spiritual surrender" mask freeze responsesWhy leaving religion is neurologically difficult-even when it feels necessaryHow to rebuild safety, trust, and meaning without replacing one authority with anotherThis is not a self-help book. It does not promise quick relief, spiritual reconciliation, or a new belief system. What it offers instead is something rarer: conceptual clarity that reduces shame, restores agency, and makes your experience intelligible at the level where it actually happened-in the body.If you have ever felt that religion took something from you that words couldn't quite name, this book gives you the language-and the map-to understand why.About the AuthorMaria Elwood Rivera is a writer and independent researcher whose work examines the impact of belief systems on the nervous system, identity formation, and long-term psychological regulation. Her focus lies in understanding how authority, morality, and transcendental threat are internalized at a physiological level, particularly within religious and high-control environments. Drawing from interdisciplinary research in trauma theory, attachment dynamics, and embodied cognition, she explores forms of harm that often remain unnamed because they are socially sanctioned or spiritually justified. Her writing emphasizes clarity, causal precision, and respect for lived experience, avoiding both polemic and reductionism. Religious Trauma in a Nutshell: When Faith Becomes a Threat to the Nervous System is part of her collaboration with In a Nutshell Press.
