Pope Warns Against Materialism This Christmas

Pope Benedict warned on Sunday against rampant materialism which he said was polluting the spirit of Christmas.

"In today's consumer society, this time of the year unfortunately suffers from a sort of commercial 'pollution' that threatens to alter its real spirit," the Pope told a large crowd gathered in St. Peter's Square to hear his weekly Angelus blessing.

He said Christmas should be marked with sober celebrations and urged Christians to display a nativity crib in their houses as "a simple but effective way of showing their faith and conveying it to their children."

Last year, under Pope John Paul, the Vatican launched a high-profile campaign to urge Roman Catholic Italy not to compromise the spirit of Christmas through excess or dilute its message out of fear of offending a growing Muslim population.
