The Christmas Oratorio (Weihnachts-Oratorium) BWV 248, is a piece by J.S. Bach intended for performance in church during the Christmas season. It was written for the Christmas season of 1734 incorporating music from earlier compositions, including three secular cantatas written during 1733 and 1734 and a now lost church cantata, BWV 248a. The date is confirmed in Bach's autograph manuscript. The next performance was not until 17 December 1857 by the Sing-Akademie zu Berlin under Eduard Grell.
