Calls for Cardinal Donald Wuerl to excommunicate or otherwise punish Vice President Joe Biden for officiating the same-sex marriage of two White House staffers this week will likely go unheeded, most church experts say.

Princeton’s Robert George called for Biden’s excommunication soon after Biden’s wedding duty was reported. But although the Catholic Church doesn’t sanctify gay marriage and considers homosexual behavior a sin, Biden didn’t actually break church law, said the Rev. James Bretzke, a theologian at Boston College.
