Sometimes those words are tossed out to say, “Have a happy day on December 25th.”
But there is a much deeper meaning. Christmas is a combination of the words Christ and mass. Mass is derived from a word meaning to send or is sent. Merry relates to joy.
Let us rejoice because Christ was sent. I do hope you have a joyous day with family, a happy day of giving and receiving gifts, a cheery day of food and celebration. But more than that, I hope you rejoice because Christ was sent and You have received him in your heart!
GOD, who makest us glad with the yearly remembrance of the birth of thine only Son Jesus Christ; Grant that as we joyfully receive him for our Redeemer, so we may with sure confidence behold him when he shall come to be our Judge, who liveth and reigneth with thee and the Holy Ghost, one God, world without end. Amen.
