“"[Elizabeth] calls Mary the mother of her Lord. This denotes a unity of person in the two natures of Christ; as if she had said, that he who was begotten a mortal man in the womb of Mary is, at the same time, the eternal God.... This name Lord strictly belongs to the Son of God 'manifested in the flesh,' (1 Timothy 3:16,) who has received from the Father all power, and has been appointed the highest ruler of heaven and earth, that by his agency God may govern all things.”
