Thompson concentrates on two things: Benedict's wish to improve liturgical practice, and his likely intention to liberalise the rules that govern the celebration of the old rite. I guess the former has the greater potential for impact on users of this forum.
Thompson believes "it has become clear that Benedict's agenda remains essentially the same as it was when he was Cardinal Ratzinger", and that his target is "not so much people as bad habits - rambling sermons; smug, self-centred celebrations of the Mass; ugly music and architecture that, in his opinion, insults God." This seems to me to be a valid observation: Benedict's carefully argued words in Sacramentum Carititatis reflect Ratzinger's published views.
As Thompson points out, the document "contained explicit instructions about the greater use of Latin and plain chant". It is therefore reasonable to expect to sing and hear more Gregorian in English parishes in the future. This was one of the main reasons for the founding of the Society, and the users of this discussion board would necessarily be involved in the process. It would therefore be interesting to hear people's views on how this can best be achieved, and the practical things the Society and the Liturgy Office might do to encourage it.
Thompson believes it might be an uphill struggle in England, observing in passing that the Exhortation has been "ignored by the English bishops." That may be true, up to a point. The summary of the document published on the Liturgy Office's website mentions music once, almost in passing. The words 'latin', 'gregorian' and 'chant' don't appear at all. To be fair, there may be nothing deliberate in this; it may just reflect the background and priorities of those involved. As John Ainslie has observed elsewhere on this board:
In Scotland there is an official national committee for church music, part of the Commission for Liturgy of the Bishops' Conference. In Ireland there is a National Centre for Liturgy at Maynooth, which runs a diploma in church music; there are similar structures in many other European countries.
In England there has been no official permanent secretariat or commission specifically for the promotion of church music at national level since the 1970s...
However, I find an uphill walk easier with the wind behind me, and in this case we know the way it's blowing. So, suggestions please ...
