“As the Holy Christmas Season comes round each year, the message of Jesus, Who is light in the midst of darkness, echoes once more from the Crib of Bethlehem in the ears of Christians and re-echoes in their hearts with an ever new freshness of joy and piety. It is a message which lights up with heavenly truth a world that is plunged in darkness by fatal errors. It infuses exuberant and trustful joy into mankind, torn by the anxiety of deep, bitter sorrow. It proclaims liberty to the sons of Adam, shackled with the chains of sin and guilt. It promises mercy, love, peace to the countless hosts of those in suffering and tribulation who see their happiness Shattered and their efforts broken in the tempestuous strife and hate of our stormy days. Pope Pius XII, Christmas Message of 1942
