Luke 2:11

11.This day is born to you Here, as we lately hinted, the angel expresses the cause of the joy. This day is born the Redeemer long ago promised, who was to restore the Church of God to its proper condition. The angel does not speak of it as a thing altogether unknown. He opens his embassy by referring to the Law and the Prophets; for had he been addressing heathens or irreligious persons, it would have been of no use to employ this mode of speaking: this day is born to you a Savior, who is Christ the Lord For the same reason, he mentions that he was born in the city of David, which could serve no purpose, but to recall the remembrance of those promises which were universally known among the Jews. Lastly, the angel adapted his discourse to hearers who were not altogether unacquainted with the promised redemption. With the doctrine of the Law and the Prophets he joined the Gospel, as emanating from the same source. Now, since the Greek word Greek, as Cicero assures us, has a more extensive meaning than the Latin word Servator, and as there is no Latin noun that corresponds to it, I thought it better to employ a barbarous term, than to take anything away from the power of Christ. And I have no doubt, that the author of the Vulgate, and the ancient doctors of the Church, had the same intention. (150) Christ is called Savior, (151) because he bestows a complete salvation. The pronoun to you (152) is very emphatic; for it would have given no great delight to hear that the Author of salvation was born, unless each person believed that for himself he was born. In the same manner Isaiah says, “Unto us a child is born, unto us a Son is given,” (Isaiah 9:6;) and Zechariah, “Behold, thy King cometh unto thee lowly,” (Zechariah 9:9.)
