We call on Christians around the world, and particularly Christian leaders, to oppose the extreme and violent “Anti-Homosexuality Bill” proposed in Uganda. We call on the Archbishop of Canterbury, Rowan Williams, to end his silence on the matter, to condemn the bill in public and to urge Ugandan Christians to oppose it. In addition to life imprisonment for consensual sexual activity between people of the same sex, the bill would introduce the death penalty for anyone whose same-sex partner is disabled. It would introduce imprisonment for anyone in authority – such as a priest or minister - who knew of homosexual activity but failed to report it. Most Christians, who hold a range of views on sexual ethics, will be horrified by these measures. By speaking out, Christian leaders can expose the hollowness of the religious rhetoric used by the bill’s supporters. Given the place of Anglicanism in Uganda, it is important that Rowan Williams adds his voice to the opposition to the bill.
