The leadership at the Washington National Cathedral has been welcoming to same-sex couples.
The dean of Washington's National Cathedral is calling homophobia a sin.
In a sermon Sunday, the Reverand Gary Hall said the church should have the courage to call homophobia and heterosexism a sin. He says "shaming people for whom they love is a sin."
Hall spoke about the killing of gay college student Matthew Shepard 15 years ago this month in Wyoming and about Tyler Clementi, a gay student who committed suicide three years ago in New York City.
Hall also hosted a forum Sunday with Shepard's mother, Judy Shepard, and with Clementi's mother, Jane Clementi. The forum was part of a weekend of events at the church devoted to gay youth.
Earlier this year, Hall announced the cathedral would begin celebrating same-sex marriages.
