Luke 3:38

What could be more beautiful, than that this holy race should begin from the Son of God, and be continued up to the Son of God; that the creature might go before in figure, and the Son of God might follow after in reality; that he who was made after the image of God, might first appear, that the true image of his eternal Father may descend from his glory. Thus did St. Luke mean to refer the origin of Christ to God, of whom he was the true and eternal Son. To shew this still more evidently, the evangelist had before introduced the Almighty speaking from heaven: This is my beloved Son, in whom I am well pleased. (St. Ambrose)
