Possibly Arinze but not Burke or Harvey.
But what everyone knows they need most is someone to carry out a thorough-going reform of the curia, face-down entrenched fiefdoms. Perhaps Arinze can do that, but his age militates against that. That he’s from an affirmative action class/nation, might give him some moral authority but on the other hand, the entrenched Italian mafioso curia types might just laugh at him.
Malcom Cardinal Ranjith of Sri Lanka is most like Benedict theologically, liturgically etc., would be a “protected-class” non-European (don’t criticize him or you’re racist) but whether he has the chops to take on the power-brokers, I don’t know. He might. He just might.
“Malcom Cardinal Ranjith of Sri Lanka ... would be a “protected-class” non-European (don’t criticize him or you’re racist)”
That only works if he were a liberal. Since he’s a conservative he’ll be labeled a dirty wog by the liberal press.
