Karen Armstrong spent seven years as a Roman Catholic nun. She entered the convent at seventeen, full of faith. She left at twenty-four, empty of it. The years between were, by her own account, a sustained experience of silence, discipline, and spiritual failure. She could not find God. She tried. God did not show up. The failure turned out to be the most important thing that ever happened to her.

She Failed at Being a Nun and Succeeded at Everything After

Armstrong left the convent in 1969 and had what she has described as a breakdown. She tried to build an academic career at Oxford, struggled with undiagnosed epilepsy, and published a memoir about her convent years that was brutally honest about the psychological damage of her experience. Through a Glass Darkly did not make her popular with the Catholic Church. Religious studies scholars at the University of London have traced how Armstrong's early failures shaped her later methodology. Because she could not find God through personal devotion, she began studying how other people found God. Because one tradition had failed her, she studied all traditions. She became, paradoxically, one of the world's leading experts on religious experience precisely because her own religious experience had been a disappointment. Her breakthrough came with A History of God, published in 1993, which traced the development of monotheism across Judaism, Christianity, and Islam simultaneously. The book treated all three traditions with equal seriousness and equal skepticism. It sold over a million copies. It was translated into thirty languages.

She Built a Charter for Compassion

In 2008, Armstrong won the TED Prize, which grants the winner a single wish for a project that could change the world. She wished for a Charter for Compassion, a document affirming that the core message of all major religious traditions is the Golden Rule: treat others as you would wish to be treated. Theologians at Georgetown University have studied the Charter for Compassion as one of the most significant interfaith documents of the twenty-first century. It has been affirmed by religious leaders across every major tradition. It has been adopted by cities around the world. It is, deliberately, not a theological statement. It does not say which God is real. It says that every tradition that has survived for more than a few centuries has arrived at the same ethical conclusion, and that this convergence matters more than the theological disagreements. Armstrong herself remains difficult to categorize. She is not religious in any conventional sense. She does not attend services. She does not pray in the way that most believers understand prayer. She has said that she finds God not in belief but in the practice of compassion, in the discipline of trying to understand people who see the world differently than she does. She was a nun who could not find God. She became a scholar who found God everywhere, not as a being to worship but as an idea that humanity keeps reinventing because it needs to. The failure was the education. Everything else was the exam.
