'In big cities, beneath the roar of traffic, beneath “the rapid pace of change”, so many faces pass by unnoticed because they have no “right” to be there, no right to be part of the city. They are the foreigners, the children who go without schooling, those deprived of medical insurance, the homeless, the forgotten elderly. These people stand at the edges of our great avenues, in our streets, in deafening anonymity. They become part of an urban landscape which is more and more taken for granted, in our eyes, and especially in our hearts'.
Pope Francis, Homily, 25th September 2015.
