Isaiah 56:5

The house and wall that are strength and security seem to describe the church that is above somewhere in the heavens, that is, over the earth. People dwell there who have grown in holiness and virtue and who shine forth and receive the honor of self-control along with a greater inheritance. They receive from God an eternal glory. There is nothing lacking of grace in them. For the rewards of self-control are great. And not only to the guileless eunuchs does he announce the provision of illustrious dignity, but he also announces it to those who keep the [new] sabbath that Christ established. For the others kept his sabbath by the law. For what was formerly in type is now illuminated in the beauty of truth.

And what could be greater than the reward the Lord bestowed upon His mother, whom He honored above all others? For He deemed no gift more abundant than virginity, as Scripture teaches us. For thus the Lord spoke through Isaiah: Let not the eunuch say, I am but a dry tree. Thus says the Lord to the eunuchs: Whoever keeps my commandments, and chooses what I desire, and embraces my covenant, I will give them a place in my house and on my wall, a name better than sons and daughters, an everlasting name will I give them, which shall not be cut off. He promises others that they will not fail: did he allow his mother to fail? But Mary does not fail, the teacher of virginity does not fail; nor could it be possible that she who carried God would think of carrying a human being.

All the pure virgins who are betrothed to Christ shall light their lamps, and with the Bridegroom they shall go into the marriage chamber. All those who are betrothed to Christ are far removed from the curse of the law and are redeemed from the condemnation of the daughters of Eve. For they are not wedded to men so as to receive the curses and come into the pains of childbirth. They take no thought of death, because they do not deliver children who will die. And in place of a mortal husband, they are betrothed to Christ. And, "because they do not bear children, there is given to them the name that is better than sons and daughters." And instead of the groans of the daughters of Eve, they utter the songs of the Bridgroom. The wedding feast of the daughters of Eve continues for only seven days. But for these virgins, the Bridegroom never leaves. The adornment of the daughters of Eve is wool that wears out and perishes, but the garments of these does not wear out. Old age withers the beauty of the daughters of Eve, but the beauty of these shall be renewed at the time of the resurrection.
