PARIS, France (AP) -- Pope Benedict XVI urges Christians to make their voices heard in France and other countries that have strong traditions of secularism. He also stated that politics and religion should be open to each other. The pope embarked last Friday on a four-day trip -- his first to France as pontiff -- that will take him from the presidential Elysee Palace to the Roman Catholic shrine in Lourdes.

Benedict expressed understanding for secular traditions, but added that, nonetheless, "Religion and politics must be open to each other. The presence of Christian values is fundamental for the survival of our nations and our societies."

After a meeting with Pope Benedict at the Elysee Palace, President Nicolas Sarkozy promoted his idea of "positive secularism" which means to uphold the separation of church and state, while considering religions as beneficial for society, instead of a danger. The French president said positive secularism could allow for a dialogue "on the meaning we want to give to our existences."

Following on the speech of Sarkozy, Benedict said he was convinced of the need for "a new reflection on the true meaning and importance" of separation of church and state. The pontiff said it was "fundamental on the one hand, to insist on the distinction between the political realm and that of religion." However societies must also be "more aware of the irreplaceable role of religion for the formation of consciences and the contribution that it can bring to -- among other things -- the creation of a basic ethical consensus within society."
