The Queen Mother?
Uniting John's portrayal of Mary at the wedding at Cana (the beginning of Jesus' earthly ministry) and at the foot of the cross (the end) is what we might call "the theme of the royal mother." John stresses Mary's maternal relationship to Jesus; his use of the term "mother of Jesus" seems to convey a certain reverence, much as it does in Luke's portrayal of the nascent Church gathered in the upper room, waiting for the coming of the Holy Spirit (Acts 1:14).

This maternal relationship of Mary to Jesus is linked to John's emphasis on Jesus' kingship, particularly in the context of his passion.

The Roman soldiers mock Jesus with the words, "Hail, King of the Jews!" (19:2) At the last it is Jesus' assertion of his kingship that becomes the decisive charge leading directly to his condemnation (19:12-15).

In John's account Jesus is even buried in a garden (19:41), like His royal ancestors, the covenanted kings of Judah (2 Kings 21:18, 26). Jesus' cross, then, is inseparable from his kingship.
Now it is in connection with Jesus' kingship on the cross that John speaks of "the mother of Jesus" (19:25). In placing this description of Mary in this context of kingship, John ...
