Archbishop of Canterbury Rowan Williams criticized some Christians for feeling so "embarrassed and ashamed and disgusted" over homosexuality that they seem unwelcoming to outsiders and convey a lack of understanding, the Religion News Service reports. Addressing a group of Christian teenagers at his Lambeth Palace residence in London, the spiritual leader of the Anglican Communion said Anglicans and other Christians are still in "quite a lot of tangles" about homosexuality. The confusion sometimes leaves the church "scratching its head and trying to work out," Williams said. His comments came barely two weeks after he slammed the British government for its plans to legalize same-sex marriages -- something that Williams said would be a mistake. The Anglican Communion itself has been deeply divided over homosexuality. The Episcopal Church, the communion's U.S. branch, allows gay bishops and sanctions same-sex commitment ceremonies, while more conservative leaders in Africa strongly denounce homosexuality. According to a report in the Daily Telegraph newspaper, Williams said that "what's frustrating is that we will have Christian people whose feelings about it are so strong, and sometimes so embarrassed and ashamed and disgusted, that it just sends out a message of unwelcome, or lack of understanding, or lack of patience. ... So whatever we think about it, we need as a church to be tackling what we feel about it."
