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.
(in Serm. Nativ. 4.) But if perhaps the swaddling clothes are mean in thy eyes, admire the Angels singing praises together. If thou despisest the manger, raise thy eyes a little, and behold the new star in heaven proclaiming to the world the Lord’s nativity. If thou believest the mean things, believe also the mighty. If thou disputest about those which betoken His lowliness, look with reverence on what is high and heavenly.
