Pope Benedict XVI's visit to the United Kingdom from 16 to 19 September 2010 was the first state visit by a pope to the United Kingdom (Pope John Paul II made a pastoral, rather than state, visit to Great Britain in 1982). The Pope Benedict XVI bibliography contains a list of works by Pope Benedict XVI.Pope Benedict XVI's visit to the United States took place from April 15, 2008 to April 20, 2008 and was his first visit to the United States. The Pope strongly condemned the Mohammed cartoons, first published by a Danish newspaper and later in other European papers, saying _In the international context we are living at present, the Catholic Church continues convinced that, to foster peace and understanding between peoples and men, it is necessary and urgent that religions and their symbols be respected._ He also added that this implies that _believers [of various religions] not be the object of provocations that wound their lives and religious sentiments._ Pope Benedict XVI noted that _for believers, as for all people of good will, the only path that can lead to peace and fraternity is respect for the convictions and religious practices of others._Pope Benedict XVI has declared his commitment to the Second Vatican Council's Ecumenism, but has stressed a hermeneutic of continuity in Catholic doctrine so that Ecumenism never really becomes a break from the bi-millennial Church tradition.The relations between Pope Benedict XVI and Judaism have remained fairly good, although concerns have been raised by Jewish leaders over the political impact of Traditionalists in the Church during the papacy of Benedict.
