Matthew 12:47

(De Nat. et Grat. 36.) But whatever may be decided concerning these brethren, yet concerning the holy Virgin Mary, (for the honour of Christ,) when sin in her is in question, I would not have it brought into doubt. For from this only we might know that more abundant grace was conferred upon her that she should overcome sin on all sides, because she merited to conceive and bring forth Him Who it is clear had no sin. It follows; Then said one unto him, Behold, thy mother and thy brethren stand without seeking thee.

(Verse 46 and following) While he was still speaking to the crowds, behold his mother and brothers stood outside seeking to speak to him. But someone said to him: Look, your mother and brothers stand outside seeking you. But he answered the one who told him, saying: Who is my mother, and who are my brothers? And stretching out his hand towards his disciples, he said. The Lord was occupied with the work of speaking, teaching the people, and fulfilling the duty of preaching, while his mother and brothers came and stood outside, desiring to speak to him. Then someone announces to the Savior that his mother and brothers are standing outside, seeking him. It seems to me that this person who announces it is not doing so by chance and simply: but is setting a trap for the Savior, whether he prefers spiritual work over flesh and blood. Therefore, the Lord, not because he denied his mother and brothers, ignored their request to go out; but because he responded to the one laying a trap, extending his hand towards his disciples, he said:

Let us also expound in another way. The Saviour is speaking to the multitude—that is, He teaches the Gentiles the inward mysteries; His mother and His brethren, that is the synagogue and the Jewish people, stand without. And when they shall have asked and enquired, and sent a messenger, they shall receive for answer, that their will is free, and that they can enter in, if they will believe.

That which I was lately saying, that when virtue is wanting all things are vain, this is now also pointed out very abundantly. For I indeed was saying, that age and nature, and to dwell in the wilderness, and all such things, are alike unprofitable, where there is not a good mind; but to-day we learn in addition another thing, that even to have borne Christ in the womb, and to have brought forth that marvellous birth, hath no profit, if there be not virtue. And this is hence especially manifest. "For while He yet talked to the people," it is said, "one told Him, Thy mother and Thy brethren seek Thee. But He saith, who is my mother, and who are my brethren?" And this He said, not as being ashamed of His mother, nor denying her that bare Him; for if He had been ashamed of her, He would not have passed through that womb; but as declaring that she hath no advantage from this, unless she do all that is required to be done. For in fact that which she had essayed to do, was of superfluous vanity; in that she wanted to show the people that she hath power and authority over her Son, imagining not as yet anything great concerning Him; whence also her unseasonable approach. See at all events both her self-confidence and theirs. Since when they ought to have gone in, and listened with the multitude; or if they were not so minded, to have waited for His bringing His discourse to an end, and then to have come near; they call Him out, and do this before all, evincing a superfluous vanity, and wishing to make it appear, that with much authority they enjoin Him. And this too the evangelist shows that he is blaming, for with this very allusion did he thus express himself, "While He yet talked to the people;" as if he should say, What? was there no other opportunity? Why, was it not possible to speak with Him in private? And what was it they wished to say? […]

Someone told him, "Your mother and brothers are standing outside, asking to speak to you." Why he said this and the need for it are explained in Luke (8:19), namely, there was such a crowd that they could not reach him. Mystically, the synagogue is …
