Family, Sex, and Faith is the first systematic examination of what the Russian Orthodox Church (ROC) teaches and how believers respond to its messages regarding issues such as marriage, divorce, contraception, abortion, husband-wife relations, and LGBTQIA+ rights. According to Pål Kolstø, for the ROC, the ethics of private life involve what Michel Foucault called "biopolitics": the state regulates the sex lives of its citizens to control the development of the population. Family, Sex, and Faith offers a systematic analysis of aspects of the moral theology of the ROC, discussing the means and strategies it employs to achieve its goals, to counter resistance, and to emerge victorious from the battles in which it is embroiled. Although the constitution defines Russia as a secular state, the ROC has achieved a privileged position in society, functioning as a major provider of ideology and legitimacy for the Putin regime.
