[[Dear Sister Laurel, I am not a scholar of Vatican II, but you seem to glow with enthusiasm over the potential for the Church in implementing more of its substance. I was wondering if you could say what else we might expect to evolve from the reforms begun? I would like to catch some of that glow for myself, though Pope Francis has already warmed my heart.]]
Many thanks for your question. It gives me a chance to reflect on precisely why I am so excited about the papacy of Francis and what kind of Church I do hope for precisely because of the reforms of Vatican II and the promise of their continued implementation in the future. We are used to thinking about Vatican II as a past event and already implemented. We celebrate the fiftieth anniversary of the Council this year and in many parishes there have been presentations on the council, on what was achieved and what was left to be achieved. For many attending those presentations what was clear was there was a tremendous excitement in the 60's and 70's, huge idealism and energy for a Church which could be the vehicle for the proclamation of the Gospel to a world truly yearning for it, a Church which really walked with people in their everyday situations and was more than a sacred oasis in the midst of chaotic profanity. However, what was also clear was the disappointment of the past 40 or so years as Vatican II's promise and challenge for reform was countered, eroded away, betrayed, or allowed to wither and die on the vines of either a "hermeneutic of continuity," or a "hermeneutic of rupture."
General Comments on the Ecclesiology of Vatican II:

You see, this Church was the one which took the humanity of Jesus seriously as well as his divinity and learned its lessons from his own accompanying of people, his profound listening to and understanding of them, his teaching in stories which allowed them the privileged space to make a decision for or against him and the Kingdom he proclaimed but who, at the same time therefore continued to teach the unremitting mercy of God who would not relent from loving and calling them all of their lives.
This was the Church whose Lord was the One characterized by kenosis (self-emptying) and asthenia (weakness), the One who died for them while they were YET sinners; for that reason he is the one whose servants, therefore, were characterized by the same things. Note well that there was no denigration of God's greatness in any of this, and no diminishment of Jesus' Lordship. (Some today are complaining that Francis' penchant for dressing simply, wearing no cuff links or a pectoral cross of a base metal, as well as addressing Cardinals while standing on the same level or being seen eating or drinking anything other than the Eucharist "denigrates the papacy" so this is an issue.) Instead it gave us a God and Lord whose authority was shown as countercultural, powerful and creative as love and mercy are always powerful and creative, and compelling precisely because it raised everyone up in the truly humble recognition of their true dignity --- something authority and power in the Constantinian model never does.
This Church was Catholic in the more Greek sense of the term "katholicos" than the Latin sense of "universalis". What I mean by this is that this Church was catholic in the sense of leaven in bread dough; there is nothing left untouched by its presence, no bits of unleavened bread remaining while the majority of the loaf is leavened. The Latin sense of universalis had more the sense of a gigantic circle into which people were brought; the problem though was that no matter how large one drew or expanded that circle there were always persons that stood outside it, and perhaps, were left to stand outside it because, for whatever reason, they did not hear the Gospel from which it supposedly lived. I am convinced that when Francis spoke recently of the solemn nonsense of proselytizing and distinguished that from evangelizing, coupled with his insistence on a church which is not turned in on itself, he was encouraging us to see and be the church which was truly Catholic in the more Greek sense of the term. It is a Church which knows that with Christ the veil between sacred and profane was definitively rent in two and that there is no place from which the Word of God or its servants cannot and should not go. Christ, after all, descended into hell so that God might be implicated there and transform reality with that presence. The Church must act in no less a Christlike way in her own missionary character.
Finally, therefore, this Church is the Pilgrim People of God. Most fundamentally it is not that there is a Church to which people are then added. Most fundamentally the Church IS the called and assembled People. It has a structure, yes, forms of governance, ways of doing business (many of which may change), and so forth, but it IS the people who are continually called by Christ and for this reason it is always learning and teaching, alway moving forward, always in need of reform, always seeking to respond to and serve its Lord with greater fidelity and sensitivity, always finding ways to be that People from which the entire "sense of the Faith" comes. Another way of saying this is to note that the Church is NOT the Kingdom of God here on earth. The Church is a privileged means towards the Kingdom, a proleptic expression of the Reign of God, but it is NOT the Kingdom. Instead the Church lives from and for the Gospel of God and the Reign it announces. She serves that Gospel and awaits the day when God will truly be all in all --- when there will be a "new heaven and new earth". Again, she is a privileged servant in this but she does not confuse herself with God's reign, nor her servants with Christ himself.
We codified this conclusion in the Joint Declaration on Justification, a document with far-reaching conclusions we should remember in determining what truly divides and what more fundamentally unites denominations. Vatican II taught this and we have a far piece to go before we begin to achieve what it had in mind. I think we will become a Church which more and more truly dialogues with others because that IS the way of evangelization. (Lecturing, apodictic pronouncements are the way of proselytization.) Only in this way will we also be the learning AND teaching Church the world needs us so very badly to truly be. What we cannot be is a Church with nothing to learn nor a Church with nothing to teach. Both of these have been tried and failed. The first corresponds in many ways to those teaching a hermeneutic of continuity (in the sense the SSPX understood this term, for instance), and the second by those embracing the hermeneutic of rupture.
Sometimes when New Testament scholars think about the importance of certain pieces of the Scriptures they recognize that had a single story been the only one to have survived until today it would have been enough. If Luke's writings, for instance had been lost but his parable of the Prodigal Sons/Prodigal Father survived we would still have Luke's' entire version of the Gospel in nuce. The Lord's Prayer functions the same way, but for that to be the case we must do more than repeat it unthinkingly. With Francis we have been given a clear charter of the way he desires to lead the Church and the Gospel life he wishes us each to model for others. If he never gave another interview, wrote another encyclical, rode another bus with people he considers his very own, or gave that brilliant smile which screams the joy of a man who knows the mercy of God, we have already been given a clear vision of the courageous and catholic Church VII called for. Vatican II was a beginning. Now we must implement it in the ways Francis is clearly indicating to us. A poor church, a joyful church, a church which lives from and proclaims the mercy of God universally and without qualification --- a truly Catholic Church which will set the world on fire with God's love and make all things new --- that is the vision Vatican II had and which Francis has already made QUITE clear he shares completely.
