A kingdom divided against itself cannot stand
Jesus went home with his disciples, and such a crowd collected that they could not even have a meal. When his relatives heard of this, they set out to take charge of him, convinced he was out of his mind.
The scribes who had come down from Jerusalem were saying, ‘Beelzebul is in him’ and, ‘It is through the prince of devils that he casts devils out.’ So he called them to him and spoke to them in parables, ‘How can Satan cast out Satan? If a kingdom is divided against itself, that kingdom cannot last. And if a household is divided against itself, that household can never stand. Now if Satan has rebelled against himself and is divided, he cannot stand either – it is the end of him. But no one can make his way into a strong man’s house and burgle his property unless he has tied up the strong man first. Only then can he burgle his house.
‘I tell you solemnly, all men’s sins will be forgiven, and all their blasphemies; but let anyone blaspheme against the Holy Spirit and he will never have forgiveness: he is guilty of an eternal sin.’ This was because they were saying, ‘An unclean spirit is in him.’
His mother and brothers now arrived and, standing outside, sent in a message asking for him. A crowd was sitting round him at the time the message was passed to him, ‘Your mother and brothers and sisters are outside asking for you.’ He replied, ‘Who are my mother and my brothers?’ And looking round at those sitting in a circle about him, he said, ‘Here are my mother and my brothers. Anyone who does the will of God, that person is my brother and sister and mother.’

Mary – “ever-virgin”
499 The deepening of faith in the virginal motherhood led the Church to confess Mary’s real and perpetual virginity even in the act of giving birth to the Son of God made man. In fact, Christ’s birth “did not diminish his mother’s virginal integrity but sanctified it.” And so the liturgy of the Church celebrates Mary as Aeiparthenos, the “Ever-virgin”.
500 Against this doctrine the objection is sometimes raised that the Bible mentions brothers and sisters of Jesus. The Church has always understood these passages as not referring to other children of the Virgin Mary. In fact James and Joseph, “brothers of Jesus”, are the sons of another Mary, a disciple of Christ, whom St. Matthew significantly calls “the other Mary”. They are close relations of Jesus, according to an Old Testament expression.
501 Jesus is Mary’s only son, but her spiritual motherhood extends to all men whom indeed he came to save: “The Son whom she brought forth is he whom God placed as the first-born among many brethren, that is, the faithful in whose generation and formation she co-operates with a mother’s love.”
A song of ascents. Much have they oppressed me from my youth, now let Israel say.
Much have they oppressed me from my youth, yet they have not prevailed.
Upon my back the plowers plowed, as they traced their long furrows.
But the just LORD cut me free from the ropes of the yoke of the wicked.
May they be scattered in disgrace, all who hate Zion.
May they be like grass on the rooftops withered in early growth,
Never to fill the reaper’s hands, nor the arms of the binders of sheaves,
With none passing by to call out: “The blessing of the LORD be upon you! We bless you in the name of the LORD!”
