From Pope Benedict XVI’s Christmas homily:
The first thing we are told about the shepherds is that they were on the watch — they could hear the message precisely because they were awake.
We must be awake, so that we can hear the message. We must become truly vigilant people. What does this mean? The principal difference between someone dreaming and someone awake is that the dreamer is in a world of his own. His “self” is locked into this dreamworld that is his alone and does not connect him with others. To wake up means to leave that private world of one’s own and to enter the common reality, the truth that alone can unite all people.
Conflict and lack of reconciliation in the world stem from the fact that we are locked into our own interests and opinions, into our own little private world. Selfishness, both individual and collective, makes us prisoners of our interests and our desires that stand against the truth and separate us from one another.
Awake, the Gospel tells us. Step outside, so as to enter the great communal truth, the communion of the one God. . . .
