By St. Cyril of Alexandria
(Commentary on Luke, Sermon 4)
The Prophet Isaiah says, "Beautiful are the feet of them that bring good tidings of good." And what could there be so sweet to learn as that God has saved the world by the mediation of the Son, in that He was made like unto us? For it is written, "that there is one God, and one Mediator of God and men, the man Jesus Christ, Who gave Himself a ransom for us." For of His own accord He descended to our poverty, that He might make us rich by our gaining what is His. Behold Him therefore as one in our estate presented unto the Father, and obedient to the shadows of the law, offering sacrifice moreover according to what was customary, true though it be that these things were done by the instrumentality of His mother according to the flesh. Was He then unrecognized by all at Jerusalem, and known to none dwelling there? How could this be the case? For God the Father had before proclaimed by the holy prophets, that in due season the Son would be manifested to save them that were lost, and to give light to them that were in darkness. By one too of the holy prophets He said, "My righteousness approaches quickly, and My mercy to be revealed, and My salvation shall burn as a torch." But the mercy and righteousness is Christ, for through Him have we obtained mercy and righteousness, having washed away our filthy vileness by faith that is in Him. And that which a torch going before them is to those in night and darkness, this has Christ become for those who are in mental gloom and darkness, implanting in them the divine light. For this reason also the blessed prophets prayed to be made partakers of His great grace, saying, "Show us Your mercy, O Lord, and grant us Your salvation."
