On the plane, 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," he said. In a speech after talks with the pontiff at the Elysee Palace, Sarkozy promoted his idea of "positive secularism" -- upholding the separation of church and state, while considering religions as beneficial for society, not a danger. The French president said positive secularism could allow for a dialogue "on the meaning we want to give to our existences."

In a speech following Sarkozy's, the pontiff said he was convinced of the need for "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 in order to preserve both the religious freedom of citizens and the responsibility of the State towards them. But he added that societies must also be "more aware of the irreplaceable role of religion for the formation of consciences and the contribution which it can bring to -- among other things -- the creation of a basic ethical consensus within society."
