A Marvellous Wonder

 "A marvellous wonder has this day come to pass:

Nature is made new, and God becomes man.

That which he was, he has remained.

And that which he was not, he has taken on himself

While suffering neither confusion nor division.

How shall I tell of this great mystery?

He who is without flesh became incarnate;

 The Word puts on a body;

The Invisible is seen;

 He whom no hand can touch is handled;

And he who has no beginning begins to be.

The Son of God becomes the Son of man;

Jesus Christ, the same yesterday, today, and for ever."

-From Orthodox Vespers on Christmas Day, The Orthodox Way, Callistos Ware
