Not since Gegory XII resigned in 1415 has a Roman pope resigned from his office while still alive. Benedict XVI has done so. Officially, because he were too weak to carry on. But the truth may be a different one: “Fokus” 11 Febr. 2013: He did not feel liked, in particular not by the German cardinals and the Conference of Bishops. To this came that iduring the last years, his secretary of state,  Tarcisio Bertone, grew more and more hostile to him.

Pope-BertoneKevin Annett on Henry Makow´s Blog 11 Febr. 2013: What sounded the death knell on Pope Benedict was his personal involvement in the bribery and money-laundering practices of the Vatican Bank, comically known as The Institute of Religious Works (IOR); and how that dirty connection gave the anti-Ratzinger faction in the College of Cardinals the lever they needed to dump the obstinate German from the papal throne. A Roman Senators I spoke with,said
“You must understand that in my country, the Mafia and the government and the Vatican are all the same people, and they really have only one concern: protecting their assets.”

The Secretary of State and the real power behind the papacy is Cardinal Tarcisio Bertone, an old insider who also engineered the sacking of Gotti Tedeschi, head of the Vatican Bank, last May.  A politician said: “Nobody becomes pope without a sordid past, because only with such liabilities can he be controlled by the Curia. It’s the same in any big company
As with the President of the United States, the Papal role is largely figurative.  Theoretically he heads the Curia, but the real boss is Secretary of State.  The Prophecy of the Popes calls this last Pope “Peter the Roman“.  There’s been buzz today on Catholic channels about Bertone’s full name being Cardinal Tarcisio PIETRO Bertone of Romano, Turin, Italy.  Tarcisio Bertone is about as institutional as you can get, and represents the old Italian crowd of the Curia, who are part of the Mob-government-papal clique that run the country and the Roman Catholic church. However, in the Curia, Bertone does not have the majority – and he is not liked.

Wikipedia: The Cardinal criticized journalists as Vatican judges were investigating leaks to Italian journalists of dozens of documents, including letters to the pope and encrypted cables from Vatican embassies around the world, several of which hint at power struggles among officials of the Holy See

Wikipedia: Bertone has been criticized by Catholic journalist Sandro Magister for having exposed Benedict XVI to public controversies surrounding episcopal nominations in Italy and Poland. Magister also writes that the problems in communications and governance that were visible during the Williamson affair can largely be attributed to Bertone. He has been vigorously attacked for lying about the Third Secret of Fatima.  A news article quoted former Philippine ambassador to the Vatican, Howard Dee, as saying that Cardinal Ratzinger had personally confirmed to him that the messages of Akita and Fatima are “essentially the same. The Akita prophecy, in part, contains the following: “The work of the devil will infiltrate even into the Church in such a way that one will see cardinals opposing cardinals, bishops against bishops. The priests who venerate Me (Mary) will be scorned and opposed by their confreres … churches and altars sacked; the Church will be full of those who accept compromises and the demon will press many priests and consecrated souls to leave the service of the Lord”

Malachi Martin was consistent all the way through; he believed that the Third Secret of Fatima had to do [...] with the internal problems of the Catholic Church.”[28] On a syndicated radio broadcast, Father Malachi Martin was asked the following question by a caller: “I had a Jesuit priest tell me more of the Third Secret of Fatima years ago, in Perth. He said, among other things, the last pope would be under control of Satan… In a taped interview with Bernard Janzen, Fr. Martin was asked the following question: “Who are the people who are working so hard to suppress Fatima?” Fr. Martin responded, “A bunch, a whole bunch, of Catholic prelates in Rome, who belong to Satan. They’re servants of Satan. And the servants of Satan outside the Church, in various organizations; they want to destroy the Catholicism of the Church, and keep it as a stabilizing factor in human affairs. It’s an alliance. A dirty alliance, a filthy alliance, but a very good alliance. In the same interview, Fr. Martin also said with respect to Lúcia that, “They’ve (The Vatican) published forged letters in her name; they’ve made her say things she didn’t want to say. They put statements on her lips she never made.”
