“For Unto Us a Child is Born” is taken from the words of the prophet Isaiah (Is 9:6):
Unto us a Son is given
And the government
Shall be upon His shoulder
And his name shall be called
The Mighty God
The Everlasting Father
The Prince of Peace
When Isaiah tells of a son being given to the faithful, he is not just talking about the neighbor’s kid. He foretells of a son presented as a gift to all who believe. And indeed, in Christ, we have not only a child but also the moment when the word became flesh and dwelt among us (Jn 1:14). And through that word, humanity is redeemed. Through Christ, death no longer has power. The gates of heaven are opened to all that would follow he who is called the Son of God.
“The kingdom of heaven is at hand,” declared John the Baptist (Mt 3:2). Yes, we believe that at the end of time Christ will establish his kingdom for all eternity (CCC 1042). But in the meantime, his kingdom exists on earth in the form of the one, holy, catholic, and apostolic Church (CCC 763). Founded by Jesus with a mission to manifest the will of God, the Church waits in hopeful anticipation for the establishment of Christ’s eternal reign.
It is very appropriate, then, for Isaiah to foretell a Prince of Peace. Not only would Jesus go on to proclaim a kingdom of love but also, when he returns, establish a heavenly domain that knows no end. At Christmas, we celebrate both a beginning and an end. We celebrate the very beginning of Christ ruling the hearts and minds of the faithful while also looking toward the end when he will come again and his “kingdom will have no end.”
