Catena Aurea · Lukasevangelium 2
And there were in the same country shepherds abiding in the field, keeping watch over their flock by night. And, lo, the angel of the Lord came upon them, and the glory of the Lord shone round about them: and they were sore afraid. And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people. For unto you is born this day in the city of David a Saviour, which is Christ the Lord. And this shall be a sign unto you; Ye shall find the babe wrapped in swaddling clothes, lying in a manger.
(Geometer.) They were alarmed at the miracle, as it follows, And they were afraid, &c. But the Angel dispels their rising fears. He not only soothes their terrors, but pours gladness into their hearts; for it follows, For, behold, I bring you good tidings of great joy, &c. not to the Jewish people only, but to all. The cause of their joy is declared; the new and wonderful birth is made manifest by the very names. It follows, For unto you is born this day in the city of David a Saviour, which is Christ the Lord. The first of these, i. e. the Saviour, has reference to the action, the third, i. e. the Lord, to the dignity of the person.
