Modern society is formulating an “anti-Christian creed” and punishing those who resist it with “social excommunication,” Benedict XVI has said in a new biography, published in Germany May 4.

In a wide-ranging interview at the end of the 1,184-page book, written by German author Peter Seewald, the pope emeritus said the greatest threat facing the Church was a “worldwide dictatorship of seemingly humanistic ideologies.”

Benedict XVI, who resigned as pope in 2013, made the comment in response to a question about what he had meant at his 2005 inauguration, when he urged Catholics to pray for him “that I may not flee for fear of the wolves.”

He told Seewald that he was not referring to internal Church matters, such as the “Vatileaks” scandal, which led to the conviction of his personal butler, Paolo Gabriele, for stealing confidential Vatican documents.

In an advanced copy of Benedikt XVI – Ein Leben (A Life), seen by Catholic News Agency, the pope emeritus said: “Of course, issues such as ‘Vatileaks’ are exasperating and, above all, incomprehensible and highly disturbing to people in the world at large.”

He continued: “A hundred years ago, everyone would have thought it absurd to speak of homosexual marriage. Today whoever opposes it is socially excommunicated. The same applies to abortion and the production of human beings in the laboratory….”

The biography, issued by Munich-based publisher Droemer Knaur, is available only in German. An English translation, “Benedict XVI, The Biography: Volume One,” will be published in the U.S. on Nov. 17….
