The planned papal November visit could be used to press Turkey on lessening restrictions on Christian churches and school, suggest Kasper. The trip to Turkey, Pope Benedict XVI's first to a Muslim country was announced just days after the Feb. 5 killing of an Italian priest, the Rev. Andrea Santoro, in the Black Sea city of Trabzon.
"Santoro's death is a shock also for Turkey to open itself a little bit to Christians," Kasper said. "I think this could be reason to reflect about it and have more openness to other religions."
