After reading the Vicar of Christ's interview, if I understand him rightly, he is not saying anything new but the interview is highly problematic.
There is a particularly Jesuit flavour to what he is saying, which boils down to bringing people to know and experience Jesus' mercy, then they will want to know the finer details of our faith. The details, the dogma serve to fine tune our knowledge of him.
At the heart of Jesuit spirituality is this encounter with the mercy of God, met in his Son on the Cross, which is life changing. Hence his motto: Miserando Atque Eligendo. There is a problem of course for those who don't believe in this mercy, for Francis God's mercy flowers in the Sacrament of Penance, that is problematic for those who have a muddled understanding of the nature of this sacrament, especially for those who would want limit it to forgiveness of major sins only or turn it into a counselling session, rather than primarily Christ's forgiveness of the tedious oft repeated lists of sins most of us come out with. There is also a problem for those who do not believe that the Gospel demands choice.
Francis' teaching can certainly be interpreted in Relativistic terms and it certainly will be but Francis is not a Relativist, he understands the principle of the hierarchy of doctrine. Not the mistaken idea that some doctrines are disposable or ignorable but that they are all subservient to the fundamental doctrine that God has Revealed His Mercy in His Son Jesus Christ. For fringe group Catholics who are obsessed with reorganisation of Church structures, superficially there might appear crumbs of comfort but actually Francis is calling us back to the centre, which is the person of Jesus Christ and to a radical following of the person of Christ. In Francis' theology a true encounter with Jesus always results in conversion.
Francis is a breath of fresh air to those on the fringes or even outside of the Church but for many inside especially many younger priests and theologians, especially those formed under JPII and Benedict, he is disconcerting. In his attempt to get the Church to turn away from the obsession with itself that has haunted it since Vatican II -see the agendas of geriatric organisations like ACTA that stink of churchiness- his message is to focus on the Church's mission, the movement to the messiness of the poor at the peripheries. For him this is more important than even pro-life lobbying, or opposition to experiments with marriage or anything else.
The problem Francis presents us with is that he presents himself as being almost a war with the institution of which he is the visible head, there is something in scripture about the dangers of a kingdom divided. The Telegraph amused me recently with a pod-cast entitled 'Can Francis save the Catholic Church?', well, only Jesus Christ can save anything, but the Church's leaders, especially the Pope, have a duty to make themselves lovable,
There are dangers for a Peronist in the Vatican, especially in a Church that still has not learnt the principle of subsidiarity and is still sees the Petrine office in Ultramontane terms. There are serious dangers too in a Pope who seems to have scant regard for both Tradition and tradition(s). There dangers too in much talked about concepts of Collegiality when one forgets that such a concept embraces not just the horizantal dimension of being in communion with the bishops throughout the world but also the vertical dimension of being in Commuion with ages past.
The answer: Pray for our Pope
