From here:

A weekend of religious-themed observances at Washington National Cathedral marking the tenth anniversary of the September 11 terrorist attacks will include a Buddhist nun and an Imam, but not an evangelical Christian, leading the head of the Southern Baptist Convention to ask President Obama to reconsider attending the event.

“A Call to Compassion” will include an interfaith prayer vigil on Sept. 11. It will feature the dean of the Cathedral, the Bishop of Washington, a rabbi, Buddhist nun and incarnate lama, a Hindu priest, the president of the Islamic Society of North America and a Muslim musician.

However, Southern Baptists, representing the nation’s largest Protestant denomination, were not invited to participate – and neither were leaders from any evangelical Christian organization.

Richard Weinberg, the Cathedral’s director of communications, confirmed that Southern Baptists were not extended an invitation to participate.

“The goal was to have interfaith representation,” he told Fox News Radio. “The Cathedral itself is an Episcopal church and it stands to reason that our own clergy serve as Christian representatives.”

Perhaps the point Richard Weinberg is missing is that, from the perspective of evangelicals, Episcopal clergy don’t serve as Christian representatives.
