Cardinal Daniel DiNardo, of the Galveston - Houston Archdiocese, is making his final preparations before heading to Rome, to help select the next pope.
Pope Benedict XVI will resign the papacy, next week, and Cardinal DiNardo will be locked in the Sistine Chapel for the secret conclave to choose a successor.
It will be the first time he's participated in the ancient proceedings, since being elevated five years ago.
He says none has offered him instruction, but is ready to do his part.
"The structure of the conclave, I have to say, is going to be totally new to me," says DiNardo, "The first time I walk into the Sistine Chapel, and you see that Last Judgement against the wall; Nothing clears the mind like the prospect of a conclave when you walk in there and they close those doors."
While the Cardinal will not discuss any specific names, he does offer an idea that the next pope must be able to appeal to Catholics beyond the developed world.
