The National Cathedral in Washington is set to hold a special prayer service for LGBT families on the day the Supreme Court is expected to rule in two cases related to gay marriage.

The 7PM service will serve to celebrate, commiserate or anticipate the high court's rulings.

“The freedom to marry the person you love is not only a constitutional right, it's a moral right. As a straight man, my church and my government have given me those rights,” the Rev. Gary Hall, the cathedral's dean, said in a statement. “Those of us from churches and synagogues and temples and mosques are saying: our faith communities are ready to extend those rights to everyone. It's time for the government to do the same.”

In January, Hall announced that the cathedral would be among the first Episcopal congregations to implement a new rite of marriage for gay 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.
