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.
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 knoweth 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 shewn 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.
