Ambrose of Milan
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.
(in Luc. 8:21.) Nor does He overthrow the duty of filial submission, which is conveyed in the command, Honour thy father and thy mother, (Ex. 20:12.) but shews that He owes more to the mysteries and relationship of His Father, than of His mother; as it follows, And stretching out his hand to his disciples, he said, Behold my mother and my brethren.
