O EMMANUEL [God with us], our King and Lawgiver, the Expected of nations and their Savior: COME,and save us, O Lord our God!

The following commentary adapted from The Church’s Year of Grace, Fr Pius Parsch (The Liturgical Press, Collegeville, 1959):

In the previous six antiphons, our cry was directed to the Messiah as He manifested Himself to the Chosen People, to the Gentiles, and in nature; now He is addressed in person and asked to remain with us as Emmanuel. Reading this final antiphon gives the feeling that a climax has indeed come. The very term Emmanuel [God with us] reveals the kindly, human heart of Jesus–He wants to be one of us, a Child of Man, with all our human weaknesses and suffering; He wants to experience how hard it is to be human. He wants to remain with us to the end of time; He wants to dwell within us, to make us sharers of His nature.

Besides the main title, the Savior is invoked by four other names.

(1) King and Lawgiver are common enough, and the combination is found in Isaiah 32:22: “The Lord is our Judge, the Lord is our Lawgiver; the Lord is our King. He will save us.” This is a joyous expression of faith and confidence. Christ functions in all these roles for our benefit. Whatever a lawgiver like Moses, a judge like Samuel, a king like David, accomplished for the good and glory of their people, that and far more the expected Savior will accomplish for us.

(2) The Messiah is next hailed as the expectation of the Gentiles and their Savior. Remember Jacob’s dying words: “The scepter will not pass from Judah, nor a ruler from his thigh, till He comes that is to be sent. He is the expectation of all the nations.” (Genesis 49:10)

The antiphon petitions: COME AND SAVE US! King, let me be Your vassal; Lawgiver, let me be Your servant; Expected Savior, let my longings be fulfilled in You. Our song closes with the words, “O Lord our God!” It is a phrase summarizing all the names and titles used in the O-Antiphons. May our hearts be always so disposed as to use the invocations sincerely and confidently.
