134 Indeed, when we open our hearts to those who are different, this enables them, while continuing to be themselves, to develop in new ways. The different cultures that have flourished over the centuries need to be preserved, lest our world be impoverished. At the same time, those cultures should be encouraged to be open to new experiences through their encounter with other realities, for the risk of succumbing to cultural sclerosis is always present. That is why “we need to communicate with each other, to discover the gifts of each person, to promote that which unites us, and to regard our differences as an opportunity to grow in mutual respect. Patience and trust are called for in such dialogue, permitting individuals, families and communities to hand on the values of their own culture and welcome the good that comes from others’ experiences”.
