Catena Aurea · Lukasevangelium 1
And the angel came in unto her, and said, Hail, thou that art highly favoured, the Lord is with thee: blessed art thou among women. And when she saw him, she was troubled at his saying, and cast in her mind what manner of salutation this should be.
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.
