Denver’s Archbishop hasn’t been invited to speak, but someone else has.

This from the Cleveland Plain Dealer:

An 86-year-old nun from Cleveland who works for a Catholic anti-poverty lobbying group has been selected to deliver the closing prayers one night during the Democratic National Convention.

“I think you have a different perspective when you’ve lived some history,” says Catherine Pinkerton, a member of the Cleveland-based religious order Congregation of St. Joseph who once served as principal of the West Side secondary school it founded, St. Joseph Academy.

Pinkerton says that she has never been an activist for either political party but that she admires Barack Obama’s “vision of where we stand as a nation and where we stand among nations” and agreed to deliver the benediction at the request of his campaign.

For the past 24 years, Pinkerton has worked for Network, a national Catholic social-justice lobby in Washington, D.C., where she works to establish international trade and investment policies that benefit the United States as well as the developing world.

“We are standing at one of the critical moments of our history,” says Pinkerton, who is still drafting the remarks she’ll deliver in Denver on Wednesday, Aug. 27.

Obama’s campaign invited a diverse group of religious leaders to offer prayers at the convention and asked Pinkerton to be among them because she’s “an icon among Catholics who has really been an inspiration to women everywhere,” said spokesman Tom Reynolds.

“For decades, she has been a national leader and a champion for working families,” Reynolds said. “Catholics across Ohio should be proud to have one of their own taking center stage at this historic event.”
