69. Let no one suppose that this praise belongs to chastity alone. For modesty is the companion of purity, in company with which chastity itself is safer. Shame, again, is good as a companion and guide of chastity, inasmuch as it does not suffer purity to be defiled in approaching even the outskirts of danger. This it is that, at the very outset of her recognition, commends the Mother of the Lord to those who read the Scriptures, and, as a credible witness, declares her worthy to be chosen to such an office. For when in her chamber, alone, she is saluted by the angel, she is silent, and is disturbed at his entrance, S. Luke i. 29 ff. and the Virgin’s face is troubled at the strange appearance of a man’s form. And so, though she was humble, yet it was not because of this, but on account of her modesty, that she did not return his salutation, nor give him any answer, except to ask, when she had learnt that she should conceive the Lord, how this should be. She certainly did not speak merely for the sake of making a reply.
