Jerusalem Post | Breaking News from Israel, the Middle East and the Jewish World:

"Pope Benedict XVI has told the Israeli ambassador to the Vatican he intends to visit the main synagogue in Cologne, Germany, in August, becoming the second pontiff in history to visit a Jewish place of worship."

Well, Peter was a visitor of synagogues as well. So that would make at least three. I see this repeated in all sorts of news. What they should write is "the first modern Pope".
