Scott Alexander reviews Rodney Stark's 'The Rise of Christianity', which examines factors contributing to Christianity's growth from a small cult to a dominant religion in the Roman Empire. Longer summary

Scott Alexander reviews 'The Rise of Christianity' by Rodney Stark, which explores how Christianity grew from a small cult to dominate Western history. Stark, a sociologist, applies modern religious study insights to early Christianity. The book argues that Christianity's growth was steady and explainable through factors like social networks, appeal to women, fertility differences, plague survival, and moral teachings. Scott analyzes each argument, finding some more convincing than others, and ultimately suggests that Christianity's unique emphasis on love and virtue may have been its most significant advantage.
