Who was the composer of both the "Christmas Symphony" and "Symphony No.3"?
Symphony No. 2 (Penderecki):  Sometimes referred to as the "Christmas Symphony" (quotations of the Christmas carol "Silent Night" occur repeatedly throughout the symphony), neither the score nor the parts (Schott Music, Mainz 45 791) make any reference to this moniker. Krzysztof Penderecki:  Among his best known works are his "Threnody to the Victims of Hiroshima", "Symphony No. 3", "St. Luke Passion", "Polish Requiem", "Anaklasis", "Utrenja", four operas, eight symphonies and other orchestral pieces, a variety of instrumental concertos, choral settings of mainly religious texts, as well as chamber and instrumental works.
