Who speaks for the Catholic church?

The Huffington Post hosted a live video discussion, Dueling Catholics, to discuss questions raised by Sister Mary Ann Walsh, Director of Media Relations for the United States Conference of Catholic Bishops,

• "The Catholic Church has a right to its "brand," Walsh argues, "which includes getting to say who validly can use its name."

and Jon O'Brien, President of Catholics for Choice,who said:

• "The Catholic church is not Apple or Google, global corporations that zealously police the use of their brand, siccing corporate lawyers on anybody who dares use their name in vain."

Talking to Huffington Post was Bill Donohue, President of the Catholic League for Religious and Civil Rights; Bethany Blankley a HuffPost Blogger, Religion and Politics Analyst; John Gehring Faith in Public Life’s Senior Writer & Catholic Outreach Coordinator; John McCarthy- Chairman of College Democrats at Catholic University; and Niall O' Dowd- Founder of Irish Central and Irish Voice.
