Happy Christmas!
Almighty God, who hast given us thy only begotten Son to take our nature upon him, and as at this time to be born of a pure Virgin: Grant that we being regenerate, and made thy children by adoption and grace, may daily be renewed by thy Holy Spirit; through the same our Lord Jesus Christ, who liveth and reigneth with thee and the same Spirit, ever one God, world without end. Amen.
(The Collect for Christmas Day)

This is what the Breaking of Bread would have sounded like on Christmas morning in about 1620 (in Germany). And don't be put off by the word 'mass' - Lutherans still used the word, but for a Protestant service of the Lord's Supper, so this is a thoroughly Protestant mass.

(And here's a Prezi with lots of information about Praetorius' mass for Christmas morning, including English translations of the texts.)
