>> reporter: good evening, brian. today we finally saw the man who is causing all the commotion here. in two public appearances, pope benedict looked every one of his 85 years, but his voice and his resolve are strong. pope benedict led a packed st. peter's basilica in a moving ash wednesday mass. reminding the faithful, they are made from dust and to dust they shall return. a message of humility, answered by an unusual demonstration of affection. a spontaneous, prolonged standing ovation for the retiring pontiff, at his final public mass. a sea of cell phones appecapturing the exit of a man praised today as a symbol and humble worker.

>> reporter: but there is plenty of maneuvering. meanwhile, the current pope is trying to keep to his regular schedule. tomorrow he meets with the pastors of rome's parishes. brian?
