Few matters produce more public interest and public anxiety than sex and religion. Much of the political contention and division in societies across the world centres on sexual topics, and one-third of the global population is Christian in background or outlook. In a single lifetime, Christianity or historically Christian societies have witnessed one of the most extraordinary about-turns in attitudes to sex and gender in human history. There have followed revolutions in the place of women in society, a new place for same-sex love amid the spectrum of human emotions, and a public exploration of gender and trans identity. For many the new situation has brought exciting liberation – for others, fury and fear. This book seeks to calm fears and encourage understanding through telling a three-thousand-year-long tale of Christians encountering sex, gender and the family, with noises off from their sacred texts.
