Ambrose of Milan
Catena Aurea · Lukasevangelium 8
Then came to him his mother and his brethren, and could not come at him for the press. And it was told him by certain which said, Thy mother and thy brethren stand without, desiring to see thee. And he answered and said unto them, My mother and my brethren are these which hear the word of God, and do it.
In a mystical sense he ought not to stand without, who was seeking Christ. Hence also that saying, Come unto him, and be enlightened (Ps. 34:6. Vulg.). For if they stand without, not even parents themselves are acknowledged; and perhaps for our example they are not. How are we acknowledged by Him if we stand without? That meaning also is not unreasonable, because by the figure of parents He points to the Jews of whom Christ was born, (Rom. 9:5.) and thought the Church to be preferred to the synagogue.
