Luke 11:27-28
At that time, as Jesus was speaking to the multitudes, a certain woman from the crowd, lifting up her voice, said to Him: Blessed is the womb that bore Thee and the paps that gave Thee suck. But He said: Yea, rather, blessed are they who hear the world of God and keep it.

Verse 28. Menounge, imo vero, yes indeed. Our Saviour does not here wish to deny what the woman had said, but rather to confirm it: indeed how could he deny, as Calvin impiously maintained, that his mother was blessed? By these words, he only wishes to tell his auditors what great advantage they might obtain by attending to his words. For the blessed Virgin, as S. Augustine says, was more happy in having our Saviour in her heart and affections, than in having conceived him in her womb. Tirinus.

27. And it came to pass, as he spake these things, a certain woman of the company lifted up her voice, and said unto him, Blessed is the womb that bare thee, and the paps which thou hast sucked. 28. But he said, Yea rather, blessed are they that hear the word of God, and keep it.
BEDE. While the Scribes and Pharisees were tempting our Lord, and uttering blasphemies against Him, a certain woman with great boldness confessed His incarnation, as it follows, And it came to pass, as he spake these things, a certain woman of the company lifted up her voice, and said unto him, Blessed is the womb that bare thee, &c. by which she refutes both the calumnies of the rulers present, and the unbelief of future heretics. For as then by blaspheming the works of the Holy Spirit, the Jews denied the true Son of God, so in after times the heretics, by denying that the Evervirgin Mary, by the cooperating power of the Holy Spirit, ministered of the substance of her flesh to the birth of the only-begotten Son, have said, that we ought not to confess Him who was the Son of man to be truly of the same substance with the Father. But if the flesh of the Word of God, who was born according to the flesh, is declared alien to the flesh of His Virgin Mother, what cause is there why the womb which bare Him and the paps which gave Him suck are pronounced blessed? By what reasoning do they suppose Him to be nourished by her milk, from whose seed they deny Him to be conceived? Whereas according to the physicians, from one and the same fountain both streams are proved to flow. But the woman pronounces blessed not only her who was thought worthy to give birth from her body to the Word of God, but those also who have desired by the hearing of faith spiritually to conceive the same Word, and by diligence in good works, either in their own or the hearts of their neighbours, to bring it forth and nourish it; for it follows, But he said, Yea rather, blessed are they that hear the word of God, and keep it.
CHRYSOSTOM. (Hom. 44. in Matt.) In this answer He sought not to disown His mother, but to shew that His birth would have profited her nothing, had she not been really fruitful in works and faith. But if it profited Mary nothing that Christ derived His birth from her, without the inward virtue of her heart, much less will it avail us to have a virtuous father, brother, or son, while we ourselves are strangers to virtue.
BEDE. But she was the mother of God, and therefore indeed blessed, in that she was made the temporal minister of the Word becoming incarnate; yet therefore much more blessed that she remained the eternal keeper of the same ever to be beloved Word. But this expression startles the wise men of the Jews, who sought not to hear and keep the word of God, but to deny and blaspheme it.
