The place of Jesus mother in relationship with Jesus is debated. Jesus at times seems very rough with Mary. One thing was for sure that at an early age Jesus knew who he was and that Joseph was not his ‘father’. As Jesus begins his ministry Mary approaches him about wine at a wedding in which he clearly states to her that she is overstepping her bounds calling her ‘woman’. On one occasion Jesus brothers and mother come to take him away thinking he has gone insane. When told his mother and brothers are waiting for him he turns to his disciples an calls them brothers, sisters and mothers. One thing is clear Jesus had a grander concept of family than just those who were blood. His concept included as he said ‘those that do the will of God”
This seems like a simple story of Jesus making sure his mother is taken care of but he exercises his right as the oldest and head of household to put her in the hands, not of any of his four brothers, but a disciple and that the youngest disciple. He was more concerned that one of those who had accepted his commandments and will protected and provided for her than one that she had simply given birth to. There is the bigger issue that he mentioned of a family that was large and included all who did his Father’s will.
This is something John himself will reflect on as he will point out that anyone who hates his brother and loves God is a lair and that Jesus is the firstborn of many brethren. The point being that the cross purchases more than redemption but births a family into existence. It is a family purchased with his sacrifice. A family that any Christian should put tremendous value on given what was paid to bring it into existence.
For us this means that no person can be excluded as not part of the family of God or potentially part of that family. Love is the basis for this family and as Jesus felt obligated to take care of his mother so must we all take care of one another. Love of God and our neighbor is not optional for a Christian. Jesus purchased this family with his own body and blood and so we must consider that whenever we deal with anyone.
All Things Rabyd 
That brief scene begs a few questions:
1) Why on the cross?
2) Why did He bypass one of His own brothers?
3) Why John?
There seems to have been a special relationship between Jesus and John (the disciple whom Jesus loved).
4) Was that why He chose John?
5) Why were they four women there at the foot of the cross?
It seems to me that there is too much made of Jesus calling His mother “woman”, because, even though He called her “woman” several times, He was not being disrespectful. Maybe calling her “woman” didn’t carry the kind of negative connotation we are assuming.
God bless!
