143 The solution is not an openness that spurns its own richness. Just as there can be no dialogue with “others” without a sense of our own identity, so there can be no openness between peoples except on the basis of love for one’s own land, one’s own people, one’s own cultural roots. I cannot truly encounter another unless I stand on firm foundations, for it is on the basis of these that I can accept the gift the other brings and in turn offer an authentic gift of my own. I can welcome others who are different, and value the unique contribution they have to make, only if I am firmly rooted in my own people and culture. Everyone loves and cares for his or her native land and village, just as they love and care for their home and are personally responsible for its upkeep. The common good likewise requires that we protect and love our native land. Otherwise, the consequences of a disaster in one country will end up affecting the entire planet. All this brings out the positive meaning of the right to property: I care for and cultivate something that I possess, in such a way that it can contribute to the good of all.
