The great moral question of our attitude towards the homeless, towards refugees and migrants, takes on a deeper dimension: do we really have room for God when he seeks to enter under our roof? Do we have time and space for him? Do we not actually turn away God himself?
We begin to do so when we have no time for him. The faster we can move, the more efficient our time-saving appliances become, the less time we have. And God? The question of God never seems urgent. Our time is already completely full.
–Pope Benedict, Christmas Eve, 2012
