John Eastman, the chairman of the National Organization for Marriage (NOM), has knocked the National Catheral's decision to perform gay weddings.

The church announced last week that it will be among the first Episcopal congregations to implement a new rite of marriage for LGBT members. However, the 106-year-old cathedral which has a storied history steeped in presidential tradition is not expected to hold a same-sex ceremony any time soon. The District of Columbia-based church only marries church members and has a lengthy waiting list.

Appearing on Fox News, Eastman suggested the Episcopal Church was harming itself.

The Episcopal Church “has increasingly embraced homosexuality, going back 10 years with Eugene Robinson's elevation to bishop of New Hampshire. And there's been a huge outcry in the church. So much so that their membership numbers are down 16 percent over the last decade. A number of local congregations have broken off and aligned themselves with other more traditional branches of the international Anglican Communion.”

“The step that the church has taken, the national church in the United States, is directly in violation of international Anglican law and the Book of Common Prayer. So, they can do this if they want but I think redefining marriage to be something it was never understood to be is going to have dramatic consequences both in this country and in their church.” (The video is embedded on this page.
