Gregory the Great
Catena Aurea · Matthäusevangelium 12
While he yet talked to the people, behold, his mother and his brethren stood without, desiring to speak with him. Then one said unto him, Behold, thy mother and thy brethren stand without, desiring to speak with thee. But he answered and said unto him that told him, Who is my mother? and who are my brethren? And he stretched forth his hand toward his disciples, and said, Behold my mother and my brethren! For whosoever shall do the will of my Father which is in heaven, the same is my brother, and sister, and mother.
(ubi sup.) Thus also His mother is declared to stand without, as though she was not acknowledged, because the synagogue is therefore not acknowledged by its Author, because it held to the observance of the Law, and having lost the spiritual discernment thereof, kept itself without to guard the letter.
