25 And behold there was a man in Jerusalem named Simeon, and this man was just and devout, waiting for the consolation of Israel; and the Holy Ghost was in him. 26 And he had received an answer from the Holy Ghost, that he should not see death, before he had seen the Christ of the Lord.
Ambrose: 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 casts out) [1 John 4:18], but that holy fear of the Lord [Ps 19:9] which abides for ever, by which the righteous man, the more ardent his love to God, is so much the more careful not to offend Him.
Well is he called righteous who sought not his own good, but the good of his nation, as it follows, Waiting for the consolation of Israel.
Gregory of Nyssa: It was not surely worldly happiness that the prudent Simeon was waiting for as the consolation of Israel, but a real happiness, that is, a passing over to the beauty of truth from the shadow of the law. For he had learnt from the sacred oracles that he would see the Lord’s Christ before he should depart out of this present life. Hence it follows, And the Holy Spirit was in him, (by which indeed he was justified), and he received an answer from the Holy Spirit.
Bede: To see death means to undergo it, and happy will he be to see the death of the flesh who has first been enabled to see with the eyes of his heart the Lord Christ, having his conversation in the heavenly Jerusalem, and frequently entering the doors of God’s temple, that is, following the examples of the saints in whom God dwells as in His temple.
