Mystical uh huh . . if you say so
Christ gave her to his disciple John to be his mother;
Whoa, back up the truck. John was already Marys son. John and Jesus were half-brothers through Mary.
so all disciples find her their own.
Nowhere does the Bible say that. They all had their own mothers.
"Mary the Mother of Christ is also seen as the Mother of the Mystical Body of Christ... Mystical uh huh . . if you say so"
The Epistles of St Paul deal with this extensively (a good place to start is "In Christ we form one body, and each member belongs to all the others." Romans 12:5.) Really revealing when you look at the depth of meaning of such an image.
"Christ gave her to his disciple John to be his mother"... Whoa, back up the truck. John was already Marys son. John and Jesus were half-brothers through Mary.
You may have your Johns mixed up. We're speaking of the son of Zebedee and Salome, and the brother of James the Greater. In the Gospels the two brothers are often called "the sons of Zebedee" after their father.
"
So all disciples find her their own..". Nowhere does the Bible say that. They all had their own mothers.
You are taking an honorific title too literally. Of course the disciples had their own mothers, just as John has his mother Salome, the wife of Zebedee.
To use a rather puny analogy, it's like calling George Washington the Father of his Country. It's not that he had rampant paternity issues with pregnant women throughout the 13 colonies; it's that he played a role which brought the United States of America "to birth."
A similar thing is said of Mary. She brought the Messiah to birth. She was also espoused by the Holy Spirit, whose overshadowing of her caused her to be with Child. Notice that this "handmaid of the Lord" is also with the Apostles in the Upper Room when the Holy Spirit comes again, this time at Pentecost, the birthday of the Church. Hence the maternal title.
This is not about biology, but about grace. Mary was "Full of Grace." That should help us see the connection. We honor her with such unprecedented titles only because she --- a lowly creature --- was so honored by God.
