Der Spiegel has an in-depth article on the dysfunctions of the Vatican, arising from all the scandals this year. Ultimately, they write, the cause is Benedict's failure to lead the Vatican administration. An excerpt:
When compared with expectations, the results of Benedict XVI's seven years as pope have been rather modest. The German pope will not be remembered much for his avowed fight to preserve the unity of the Church. Instead, he will be remembered as a victim of circumstances and of fragmented, competing factions, as a pontiff plagued by scandals, mistakes and gaffes. He even built walls back up that seemed to have been worn down long ago. His papacy has consisted of years of ongoing apologies and alleged or actual misunderstandings.
He has annoyed the Protestants by declaring that denominations other than his own are not true churches. He has alienated Muslims with an inept speech in the Bavarian city of Regensburg. And he has insulted Jews by reinserting a prayer for the conversion of the Jews into the Good Friday liturgy.
