BERLIN—Pope Benedict XVI warned against the growing apathy toward religion in his homeland on the first day of his first state visit to Germany that has drawn both the faithful and angry protesters.

"We are witnessing a growing indifference to religion in society, which considers the issue of truth as something of an obstacle in its decision-making, and instead gives priority to utilitarian considerations," Pope Benedict said after meeting with German President Christian Wulff. "Religion is one of these foundations for a successful social life."
