Oh, we poor men that we should be so cold and indifferent to this great joy which has been given us. This indeed is the greatest gift, which far exceeds all else that God has created. And we believe so feebly even though the angels proclaim and preach and sing, and their song is fair and sums up the whole of Christian religion, for ‘glory to God in the highest’ is the very heart of worship. This they wish for us and bring to us in Christ.

Martin Luther
Christmas Eve 1538
