Luke 1:29

For if Mary had known that similar words had been addressed to others, such a salutation would never have appeared to her so strange and alarming. When the angel saw that she was troubled at this unusual salutation, calling her by her name as if she was well known to him, he tells her she must not fear, as it follows; And the angel said, Fear not, Mary.

(sup.) But as she might be accustomed to these visions, the Evangelist ascribes her agitation not to the vision, but to the things told her, saying, she was troubled at his words. Now observe both the modesty and wisdom of the Virgin; the soul, and at the same time the voice. When she heard the joyful words, she pondered them in her mind, and neither openly resisted through unbelief, nor forthwith lightly complied; avoiding equally the inconstancy of Eve, and the insensibility of Zacharias. Hence it is said, And she cast in her mind what manner of salutation this was, it is not said conception, for as yet she knew not the vastness of the mystery. But the salutation, was there aught of passion in it as from a man to a virgin? or was it not of God, seeing that he makes mention of God, saying, The Lord is with thee.

(Diem Nat. Orat. in Christi.) Far different then to the news formerly addressed to the woman, is the announcement now made to the Virgin. In the former, the cause of sin was punished by the pains of childbirth; in the latter, through gladness, sorrow is driven away. Hence the angel not unaptly proclaims joy to the Virgin, saying, Hail.

Mark the virgin by her manner of life. Alone in an inner chamber, unseen by the eyes of men, discovered only by an angel; as it is said, And the angel came in unto her. That she might not be dishonoured by any ignoble address, she is saluted by an angel. But mark the Virgin by her bashfulness, for she was afraid, as it follows; And when she heard, she was troubled, It is the habit of virgins to tremble, and to be ever afraid at the presence of man, and to be shy when he addresses her. Learn, O virgin, to avoid light talking. Mary feared even the salutation of an angel. She wondered also at the new form of blessing, unheard of before, reserved for Mary alone.

Maria, in Hebrew, is the star of the sea; but in Syriac it is interpreted Mistress, and well, because Mary was thought worthy to be the mother of the Lord of the whole world, and the light of endless ages.
