Cyril of Alexandria
Catena Aurea · Lukasevangelium 2
And when the days of her purification according to the law of Moses were accomplished, they brought him to Jerusalem, to present him to the Lord; (As it is written in the law of the Lord, Every male that openeth the womb shall be called holy to the Lord;) 24 And to offer a sacrifice according to that which is said in the law of the Lord, A pair of turtledoves, or two young pigeons. And, behold, there was a man in Jerusalem, whose name was Simeon; and the same man was just and devout, waiting for the consolation of Israel; and the Holy Ghost was upon him.
(ubi sup.) But let us see what these offerings mean. The turtle dove is the most vocal of birds, and the pigeon the gentlest. And such was the Saviour made unto us; He was endowed with perfect meekness, and like the turtle dove entranced the world, fillinga His garden with His own melodies.There was killed then either a turtle dove or a pigeon, that by a figure He might be shewn forth unto us as about to suffer in the flesh for the life of the world.
