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.
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.
