Pope Benedict has been meeting religious leaders, on the second day of his visit to Germany.
He told Muslim representatives in Berlin on Friday that they can expect cooperation and support from Roman Catholics, as long as they respect the country’s constitution.
Germany is home to around four million Muslims, many of whom have Turkish roots.
After the meeting, the Pope left for the eastern German city of Erfurt. He met Protestant leaders in the Augustine monastery, before attending a service. The monastery is where the 16th century reformer Martin Luther once lived.
The Pope is spending Friday concentrating on issues of Germany’s divided past, both spiritual and political.
The Pontiff also has a busy weekend ahead on Saturday, he will hold an open-air mass in Erfurt before travelling to the largely Catholic city of Freiburg.
On Sunday, he will meet judges of Germany’s constitutional court, before holding mass, as he rounds off his visit.
