Can indirection bring us closer to Christ?

Since we speak at least one common language, perhaps this illustration will shed some light on what Catholics gain by Marian consecration.

Encapsulation

Mary is not the head of the Catholic Church, she is however, the superclass from which all Christians descend. In my Marian consecration, each day I promise to devote all my prayers, actions and sacrifices to her to further the work of her Divine Son. My public methods, my private methods and my protected methods all should point to Christ. I do all these things poorly, in imitation of she who did these things well and was blessed by God for her faith and purity of heart.

Polymorphism

Marian consecration takes on many, many forms. The form you mentioned, the form I did 9 years ago at one of the lowest spiritual points in my personal life, is the consecration of St. Maximilian Kolbe who spread devotion to the Miraculous Medal given to St. Catherine Laborre at Rue De Bac (in the middle of Paris). He took the message from Poland to Nagasaki and finally died in a concentration camp in Auschwitz, but his particular devotion of starting "Marytowns" spread all the way to Libertyville, Illinois. Marian consecration really goes back to St. Louis De Montfort in the 18th century. Devotion to the Heart of Mary comes straight out of the Bible, who Simeon foretold a sword would pierce. Is the Heart of Mary, Jesus is that passage even referring to Mary? Who can know such things. Fortunately, through the grace of polymorphism, we can overload the devotion with as much as we want and never find it failing to point to Christ.

Inheritance

Mary's ancestors, as well as Josephs were through the Davidic line. If we take her into our home, if we esteem her like Solomon esteemed his mother then we do what we can to help our cause to become coheirs to the kingdom. However, the abstraction fails, we're not gnostics, we don't gain access to Christ's protected methods (those hidden outside of revelation). But we can meditate on them.

Abstraction

I think this hits your observation about indirection. When we conform ourselves to Christ, we want to take on His attributes. You want to be in Him? You want Him to be in you? Learn from the one who took Him not only into her home, but in to her body. Mary is the Church, the Church is the bride of Christ, the Church is the Body of Christ. There's no way to understand these mysteries, except through a mirror abstractly.

I hope that helps, it was fun to write but probably exceptionally useless in the long run.

If you will indulge me in a section of "The Great Divorce," by C.S. Lewis. In chapter 3, a deceased bishop (the "Ghost") who is in hell but does not understand that he is, insists on arguing with a friend of his (the "Spirit") - a "Solid" person who wants to bring him to God. Unfortunately, the poor bishop is so wrapped up in his own theology, that he is simply unwilling to be brought into the fullness of heaven. The exchange goes as such:

"There is no meantime," replied the other. "AH that is over. We are not playing now. I have been talking of the past (your past and mine) only in order that you may turn from it forever. One wrench and the tooth will be out. You can begin as if nothing had ever gone wrong. White as snow. It's all true, you know. He is in me, for you, with that power. And- I have come a long journey to meet you. You have seen Hell: you are in sight of Heaven. Will you, even now, repent and believe?"

"I'm not sure that I've got the exact point you are trying to make," said the Ghost.

"I am not trying to make any point," said the Spirit. "I am telling you to repent and believe."

"But my dear boy, I believe already. We may not be perfectly agreed, but you have completely misjudged me if you do not realise that my religion is a very real and a very precious thing to me."

"Very well," said the other, as if changing his plan. "Will you believe in me?"

"In what sense?"

"Will you come with me to the mountains? It will hurt at first, until your feet are hardened. Reality is harsh to the feet of shadows. But will you come?"

"Well, that is a plan. I am perfectly ready to consider it. Of course I should require some assurances ... I should want a guarantee that you are taking me to a place where I shall find a wider sphere of usefulness-and scope for the talents that God has given me-and an atmosphere of free inquiry-in short, all that one means by civilisation and- er -the spiritual life."

"No," said the other. "I can promise you none of these things. No sphere of usefulness: you are not needed there at all. No scope for your talents: only forgiveness for having perverted them. No atmosphere of inquiry, for I will bring you to the land not of questions but of answers, and you shall see the face of God."

The indirection is a tool used by the Spirit to bring the Ghost towards Christ. The bishop is so unable to trust in the reality of God that he simply does not understand what he must do. So, the Spirit says to his friend, "Will you believe in me?"

This isn't entirely allegory here. People can be so far from God that they require someone they recognize to lead them back on the path towards Christ. The reason behind the incarnation was precisely that we limited human beings cannot relate to God in His fullness. So, God became man to intermediate that relationship - to put a veil on his own majesty - for the sake of bring us to him.

Thus, that indirection may be a tool by which an omnipotent God could woo rather than overpower those whom he would call to himself. If that is in the guise of Mary, as long as it leads back to Christ, then who am I to argue with his methods?
