Hi Neal,
Sure, I'd be happy to respond. I didn't see your initial post, to which you would like a reply.
Could you please give me your warrant for going from the fact that Christ gave Mary to John to your assertion that Jesus asks that we return to him through Mary?
Well, first of all, Jesus didn't give Mary to John. The text reads that Jesus gave Mary to the beloved disciple.
John's Gospel is mystical on numerous accounts. He narrates history in a theological manner wherein his words, phrases, and structure has an explicit intention to convey truths that are not verbally expressed as we would have them.
John begins his Gospel by presenting the redemption as a New Creation wherein Christ is the bridgegroom and the Church is the Bride - and we enter into this marriage through the sacrament of baptism.
The famous Protestant exegete Oscar Cullman has written a great commentary on the Gospel of John entitled Early Christian Worship. I wholly encourage you to check it out from your seminary library (or get it on an inter-library loan) and see what he has to say. It's also available through Amazon.com and other booksellers.
Essentially, a careful analysis of the Gospel of John and the Synoptics would lead you to see that the beloved disciple is John the Apostle (not conclusively, but convincingly enough), but that is besides the point. John has a reason for describing this particular character as "the beloved disciple". It is part of his intention in affirming theological truth - not a random coincidence to be cast aside.
As long as one reads the text on the surface without understanding the deep allusions John is making, one will fail to comprehend the height, breadth, and depth of John's Gospel, and so this remains true for what happens at the Crucifixion.
With all of that said, I propose to you that John demonstrates how Mary is the New Eve, the mother of the humanity of the New Creation (essentially, Christians), Jesus is the New Adam, and the Church is born through Eucharist (blood) and Baptism (water) from the side of Christ as Eve was born through the side of Adam as Adam slept (so Christ slept on the Cross). At least, this is how the Early Church Fathers read John's Gospel. These interpretations are not new; they're "apostolic".
Mary is, essentially, the archetype of the Church as New Eve. What can be said of Mary can be said of the Church and vice versa. This is drawn out in Revelation 12 where one would think the woman is Israel, no.. the Church, no.. Mary. Which is it? In a sense, all three - because Mary's person and character is a very sign of the nature of the Church. She is an eschatological sign. Her assumption prefigures our share in the resurrection. Her queenship prefigures our heavenly reign with Christ as his saints.
If Mary is our mother, then in what sense? This is where Marian mediation comes to the fore, which is a whole other subject. I believe - in accord with the Apostolic Tradition - that Mary has a role in heaven that corresponds to the Queen Mother's role in the Old Testament now that she is the Queen Mother who rules alongside her divine son, the Christos.
