Ordinarily, women are more religious than men. But these are no ordinary times. In America, where Christianity is still the most common religion, women are vacating churches. In the past decade, 16 million women have left the church. Younger women are disaffiliating from religion faster than men. My forthcoming book, Damned If She Does, explores the reasons American women are leaving behind institutional Christianity and offers the new face of women’s spirituality (from unchurched belief in Jesus to astrology to atheism to ancestral veneration), and what it means for the future of religion in America.
