Then came to him his mother and his brothers, and could not reach him for the crowd.
All Commentaries on Luke 8:19 Go To Luke 8
Ambrose of Milan
AD 397
The moral teacher who gives himself an example to others, when about to enjoin upon others, that he who has not left father and mother, is not worthy of the Son of God, first submits Himself to this precept, not that He denies the claims of filial piety, (for it is His own sentence, He that knows not his father and mother shall die the death,) but because He knows that He is more bound to obey His Father's mysteries than the feelings of His mother. Nor however are His parents harshly rejected, but the bonds of the mind are shown to be more sacred than those of the body. Therefore in this place He does not disown His mother, (as some heretics say, eagerly catching at His speech,) since she is also acknowledged from the cross; but the law of heavenly ordinances is preferred to earthly affection.
In a mystical sense he ought not to stand without who was seeking Christ. Hence also that saying, Come to him, and be enlightened. 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, and thought the Church to be preferred to the synagogue.
