For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counselor, The mighty God, The everlasting Father, The Prince of Peace.
All Commentaries on Isaiah 9:6 Go To Isaiah 9
Ambrose of Milan
AD 397
Christ, then, is the beginning of our virtue. He is the beginning of purity, who taught maidens not to look for the embraces of humanity but to yield the purity of their bodies and minds to the service of the Holy Spirit rather than to a husband. Christ is the beginning of frugality, for he became poor, though he was rich. Christ is the beginning of patience, for when he was reviled, he reviled not again. When he was struck, he did not strike back. Christ is the beginning of humility, for he took the form of a servant, though in the majesty of his power he was equal with God the Father. From him each various virtue has taken its origin.
For this cause, then, that we might learn these different virtues, “a son was given us, whose beginning was upon his shoulder.” That “beginning” is the Lord’s cross—the beginning of strong courage, wherewith a way has been opened for the holy martyrs to enter the sufferings of the holy war.
