Opponents of gay marriage are expressing disappointment but not surprise at the announcement that the Washington National Cathedral will now wed same-sex couples, CBN News reports. Peter Sprigg of the Family Research Council said the Episcopal Church, which operates the cathedral, "has been moving away from Christian orthodoxy on the subject of sexuality" for years. He predicted the decision would accelerate the denomination's long-running decline in membership. Thomas Peters of the National Organization for Marriage said the cathedral's announcement showed that "marriage is really an all-or-nothing deal." He added that Americans must ask whether they want to retain traditional marriage or "fundamentally give it up."
