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. 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. And it was revealed unto him by the Holy Ghost, that he should not see death, before he had seen the Lord’s Christ. And he came by the Spirit into the temple: and when the parents brought in the child Jesus, to do for him after the custom of the law, Then took he him up in his arms.
Not only did Angels and Prophets, the shepherds and his parents, bear witness to the birth of the Lord, but the old men and the righteous. As it is said, And, behold, there was a man in Jerusalem whose name was Simeon, and he was a just man, and one who feared God. For scarcely is righteousness preserved without fear, I mean not that fear which dreads the loss of worldly goods, (which perfect love casteth out,) (1 John 4:18) but that holy fear of the Lord which abideth for ever, (Ps. 19:9.) by which the righteous man, the more ardent his love to God, is so much the more careful not to offend Him.
