He’s replacing Cdl Martino, a real left-wing loon who had never met an NGO or a statist program that he didn’t love. However, I think a lot of Africans are a little shaky on this doctrine stuff, including some who have made it fairly far up in the Church. I think there was a bit too much haste to get Africans into the heirarchy and in some cases they are not very orthodox (their doctrine is all over the place, and they support condoms, polygamy, witch doctors, etc.).
This might be a smart move. Pope want to keep on eye on Cardinal Turkson by giving him office in Vatican. Such tactic might open a door for some more committed bishop to run this African country.
