Roughly 60,000 people packed a soccer stadium in Yaounde, Cameroon, today to hear Pope Benedict XVI’s first giant African mass, the BBC reports. The pontiff used his sermon to warn the throngs of the dangers of urbanization and materialism. Earlier, Benedict met with Cameroon’s Muslim leaders, and said the peaceful relationship between the country’s Christians and Muslims should be a “beacon to other African nations.” (More Pope Benedict XVI stories.)
