Cyril of Alexandria
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.
But that which is in the middle, namely, Christ, has reference to the adoration, and signifies not the nature, but the compound substance of two natures. For on Christ our Saviour we confessthe anointing to have been performed, not however figuratively, (as formerly on kings by the oil,) and as if by prophetic grace, nor for the accomplishment of any work, as it is said in Isaiah, Thus saith the Lord to his anointed, to Cyrus; (Isa. 45.) who although he was an idolater was said to be anointed, that he might by the decree of Heaven take possession of the whole province of Babylon; but the Saviour as man in the form of a servant, was anointed by the Holy Spirit, as God He Himself by His Holy Spirit anoints those that believe on Him.
