The Christmas Oratorio (German: Weihnachts-Oratorium), BWV 248, is an oratorio by Johann Sebastian Bach intended for performance in church during the Christmas season. It was written for the Christmas season of 1734 and incorporates 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.
