Ian Oliver, the pastor for the University Church at Yale has written a marvelous poem called “A Christmas Prayer.” For the whole poem, see here. A part of it reads:
If God can lie down in a cattle-trough,
is any object safe from transformation?
If peasant girls can be mothers to God,
Is any life safe from the invasion of the eternal?
If all this could happen, O God,
What places of darkness on our earth
are pregnant with light waiting to be born this night?
Susan Stabile quotes the same excerpt at Creo en Dios. Her brief reflection is worth reading.
