Book excerpt: From Pulitzer Prize-winning author and former Christian Scientist Caroline Fraser comes the first unvarnished account of one of America's most controversial and little-understood religious movements. Millions of Americans – from Lady Astor to Ginger Rogers to Watergate conspirator H. R. Haldeman – have been touched by the Church of Christ, Scientist. Founded by Mary Baker Eddy in 1879, Christian Science was based on a belief that intense contemplation of the perfection of God can heal all ills – an extreme expression of the American faith in self-reliance. In this unflinching investigation, Caroline Fraser, herself raised in a Scientist household, shows how the Church transformed itself from a small, eccentric sect into a politically powerful and socially respectable religion, and explores the human cost of Christian Science's remarkable rise. Fraser examines the strange life and psychology of Mary Baker Eddy, who lived in dread of a kind of witchcraft she called Malicious Animal Magnetism. She takes us into the closed world of Eddy's followers, who refuse to acknowledge the existence of illness and death and reject modern medicine, even at the cost of their children's lives. She reveals just how Christian Science managed to gain extraordinary legal and Congressional sanction for its dubious practices and tracks its enormous influence on new-age beliefs and other modern healing cults. A passionate exposé of zealotry, God's Perfect Child tells one of the most dramatic and little-known stories in American religious history.
