As Americans and in other protestant countries, the Angels quote’s for Christs birth in the Christmas cards is the protestant version. “Glory to God in the highest, and on earth peace, good will toward men.” Luke 2:14..The original Catholic version was “Glory to God in the highest; and on earth peace to men of good will.” Now I won’t go so far as to say that the protestant version is heretical but if we are to take the word Good, which comes from God and replace it with the word God, you have, theirs “God will’s toward men.” and ours “peace to men of GODS will.” As you can see theirs the emphasis is on MAN and ours on GOD. Unfortunately the new Catholic Bibles have, something like, “peace to those favored men.”
Let us Catholics remember that this symbol, the Manger scene, though relatively new (being attributed to Saint Francis of Assisi) is a visible reminder of our Faith in the Word made flesh. It is surrounded with the symbolism that invokes the fulfillment of God’s promise to our first parents: “I will put enmities between thee and the woman, and thy seed and her seed: she shall crush thy head, and thou shalt lie in wait for her heel.” [Gen. 3:15] in the humility of Mary expressed in the humble circumstances of the birth in a stable, confounding the pride of Satan and his minions.
For, this day, is born to you a Saviour, who is Christ the Lord, in the city of David.  And this shall be a sign unto you. You shall find the infant wrapped in swaddling clothes, and laid in a manger.  And suddenly there was with the angel a multitude of the heavenly army, praising God, and saying:  Glory to God in the highest; and on earth peace to men of good will.
And yes according to the Bible Jesus was born somewhere between December 15 and January 10 and even though the Roman emperor Aurelian gave us a Sun God Holiday to celebrate on the 25th of December that just worked out beautifully for the Church.
A Blessed Merry Christmas and a protective New Year.
Grace be with you, through Mary our Hope. In Christ, Joseph
