I love these short but beautiful verses that refer to Christ under a different title each day beginning on December 17 and continuing until Christmas. For me, each title reflects a different aspect of God in the person of Jesus Christ.
Here are the seven titles refered to in each of the antiphons. When the acrostic is read backward, it forms the Latin phrase Ero Cras which means Tomorrow I come.
O Wisdom that comest out of the mouth of the Most High, that reachest from one end to another, and orderest all things mightily and sweetly, come to teach us the way of prudence!
And the spirit of the Lord shall rest upon him: the spirit of wisdom, and of understanding, the spirit of counsel, and of fortitude, the spirit of knowledge, and of godliness. And he shall be filled with the spirit of the fear of the Lord, He shall not judge according to the sight of the eyes, nor reprove according to the hearing of the ears.
This also is come forth from the Lord God of hosts, to make his counsel wonderful, and magnify justice.
