Personally, I hope the pope does not act on this petition. I see it as theologically problematic, due to the high likelihood of it being misunderstood and misconstrued by Catholics and non-Catholics alike. The petition is pastorally unnecessary and hugely inopportune.
Patrick is a good Catholic man and one of the great Catholic apologists of our time. He is also my friend. The position he is espousing here is taken by many other good Catholics as well so I am not questioning his Catholicity or his faithfulness to the Church. But on this matter I must take exception with him.
I don't agree. Every Mariology text book in the last 100 years has included the rationale for seeing the BVM as Co-Redemptrix and Mediatrix of all Graces. The Patristic evidence for the Spiritual Motherhood of Mary dates back to the mid 2nd Century and includes statements by St. Justin Martyr and St. Irenaeus. The Popes in the last 160 years -- up to and including Pope John Paul II -- have been strong supporters of the Spiritual Motherhood of the BVM and taught such in their encyclicals. The Eight Chapter of Lumen Gentium specifically gave the BVM the titles Advocate, Auxiliatrix, Adjutrix, and Mediatrix. This statement by a General Council means that the Spiritual Motherhood of the BVM is already OFFICIAL CATHOLIC TEACHING. Raising such a teaching to a dogma therefore adds nothing to the Catholic faith that has not already been proclaimed by the Magisterium but it does make it clear that the BVM has a role to play in salvation and that this is a central tenet of the Holy Catholic Faith that is not negotiable.
The opinions and sensibilities of Protestants and other non-Catholics about Catholic teaching should be of no concern to the Catholic Church. These outsiders are a mish-mash of unbeleivers, heretics, apostates, and schismatics albeit most of them are only materially so. Are we not to proclaim the divinity of Christ because the Jehovah's Witnesses might take offense? Are we going to suppress calling Jesus the Son of God because it makes the Muslims unhappy? Do we avoid calling Jesus the Messiah because the Jews will balk?
What other things are we going to suppress to assuage the Protestants? The Substantial Presence of Christ in the Eucharist? Apostolic Succession? The indissolubility of SACRAMENTAL marriage? The anathemas of Trent?
If we Catholics are people of faith, we must profess a robust faith, not one that bends to the objections of infidels. My experience with anti-Catholic bigots is that they have no scruples about dissing us no matter what concessions we make. So we should make no concessions. None of them have any scruples about mocking Catholics, our Church and our beliefs. I am unaware of any Protestant denomination that has refrained from taking a doctrinal position becasue it might offend Catholics. Think of it: women priests, women bishops, LESBIAN bishops, abortion, contraception, divorce with remarriage, Homosexuality, IVF, defective forms of baptism. If they do not restrict their doctrine to assuage us, why are we doing so to assuage them?
Vatican II made a few off-hand comments that anyone with savvy would have recognized as attacks on Communism. Yet it never attacked the Communists by name. Many Traditionalists saw this as a capitulation to the enemy. Now 40 years later we can see it for what it was. Communism was a flash in the pan and it did not deserve anymore than trivial attention. Mere men did not know that in the 1960s. They did not know that within 25 years, Communism would be relegated to the ash-heap of history. But the Holy Spirit knew, and he moved the Council to basically ignore Communism except as a trivial nuisance. Protestantism deserves the same kind of pejorative neglect.
Meanwhile the BVM in her own words "magnifies the glory of God". She prophesied about herself that "all generations shall call me blessed".
Glory and honor is due to the greatest human person who every lived: the Blessed Virgin Miriam, Mother of God and Mother of the Church. Do not let the whining of non-Catholics silence our praises of her and her Son!
Omnes semper - ad Jesum, per Mariam, cum Petro.
