With the vote to bless same-sex marriages, the Episcopal Church becomes the largest U.S. denomination to officially sanction same-sex relationships. Homosexuality has become a flashpoint at the intersection of religion, family, and politics. A Thorn in the Flesh: How Gay Sexuality is Changing the Episcopal Church tells the story of how homosexuality has been used to further conservative political agendas, both here and abroad. It describes how African and Asian churches have been drawn into a conflict that began in the United States in the Episcopal Church, and raises vital questions of whether people with different understandings of authority and truth can live in harmony.

This provocative book is not a history of the movement for gay inclusion, nor a history of the movement for a new, conservative Anglican church in the Americas. Instead, it is a comparison of the conservative and the liberal parts of the church. There are those, such as the Church of England, who have conservative theological orientation and are most likely to oppose fully including gays and lesbians in the church. Hall, also, explores the rapid changes that have happened in Western society in the past fifty years that have led to the acceptance of same-sex marriage and homosexuality. This change has not come easily and even after nearly four decades, gay marriage remains a politically divisive issue in the United States and England.
