From the interview with Msgr. Guido Marini, Master of Pontifical Ceremonies with L’Osservatore Romano. My translation, emphases and comments:
L’ OssRom: In the recent visit to Santa Maria di Leuca and Brindisi the Pope distributed Communion to the faithful on the tongue and kneeling. It his a practice destined to become habitual in papal ceremonies?
Msgr. Marini: I really think so. In this regard it is necessary not to forget that the distribution of Communion in the hand remains, even now, from the juridical standpoint, an indult from the universal law, [the exception to the rule, not the norm!] conceded by the Holy See to those bishops conferences which requested it. The method adopted by Benedict XVI tends to underscore the force of the norm valid for the whole Church. In addition, one could perhaps also note a preference for using this method of distribution [He means the Pope's own preference.] which, without taking anything from the other, [Uh huh. Right.] better sheds light on the truth of the Real Presence in the Eucharist, it helps the the devotion of the faithful, introduces them more easily to a sense of mystery. [It's all about MYSTERY folks!] Aspects which, in our time, speaking pastorally, it is urgent to highlight and recover.
Remember! He understands that liturgy is the tip of the spear!
In his Marshall Plan for the Church, the liturgy plays an essential role, without which nothing else can be accomplished.
The Pope is trying to bring us back to ad orientem worship and reception of Communion kneeling and on the tongue. This is all about the Church liturgy being a locus of encounter with MYSTERY, with a sense of awe at transcendence.
I think the Pope wants everyone to move in this direction.
Therefore, he will keep the focus on the liturgy and what he is doing, slowly but steadily walking us back from some of the things that have happened in last decades. He is changing the conversation.
To get at my thought about this, perhaps it would be useful to check this out.
On the very day that mighty gift Summorum Pontificum went into effect, 14 September 2007, I was at the parish of His Hermeneuticalness, the inimitable Fr. Tim Finigan in Blackfen, England. I gave the sermon for the Solemn Mass to mark that wonderful day. I wanted to emphasis that what we do in the Church is not about nostalgia, or curiosity, or intellectual stimulation. Instead, it has to do with the deepest needs of the human person. The Cross, and even its proper placement during Mass, brings us to an encounter with Mystery.
My recording of the actual sermon didn’t work, so I had to read record the sermon separately. I then incorporated it into a PODCAzT (which also deals with Augustine and also women’s chapel veils). Still, this could be you a glimpse at my theological understand of these liturgical moves the Pope is making and why I think they are so important.
