Private property

Ah ! I was wondering what was the position of Christian religion on private property. Here is a quote from Pope Jean-Paul II, reported by Howard Zinn in "Passionate Declarations" (in Chapter "Communism and anti-communism"):

For instance, in 1981, Pope John Paul II issued a papal encyclical On Human Work, in which he said the Church believed in ownership and private property, but that "Christian tradition has never upheld this right as absolute and untouchable... The right to private property is subordinated to the right to common use, to the fact that goods are meant for everyone."
