The Anglican Church slapped down its American branch last month, punishing it for authorizing same-sex marriages.The church has been riven for decades over issues of female ordination, the ordination of gay clergy and, now, same-sex marriage. The issue is so incendiary that it threatened to tear the global church apart. Archbishop of Canterbury Justin Welby, the head of the church, is credited with preventing a complete implosion.Yet even in the seeming backlash to gay marriage, one of Canada’s top Anglicans says he sees signs of progress.Rev. Peter Elliott, the dean of Christ Church Cathedral in downtown Vancouver and the Number 2 Anglican in the region after the bishop, has been at the heart of this debate for years and the local diocese — for historical reasons called New Westminster — is (in)famous for its progressive stand on the topic. The diocese offers a blessing for same-sex marriages, but solemnization of marriages is a national decision and the Canadian church is expected to vote this year on the topic, potentially opening a new front in the long battle.
