John Chrysostom
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.
(Hom. xliv.) But mart the loftiness of His brethrena; when they should have come in and heartened with the crowd, or if they would not this, to have waited the end of His speech, and then to have approached Him—they on the contrary call Him out to them, and do this before the multitude, therein shewing their superabundant love of honour, and also, that with all authority they lay their commands upon Christ. This the Evangelist covertly hints when he says, While he yet spake; as much as to say, Was there no other time? But what did they seek to say? Was it aught of the dogmas of truth? then should they have brought it forth before all, that all might profit thereby. But if of other things that concerned themselves alone, they should not have called Him in such haste, whence it is plain that they did this out of vain glory.
