If I was adding to my imaginary forthcoming volume Liturgical Birds and their Plumage there would probably be three entries under the genus Liturgica.
(i) Common Garden (Liturgica ferialis) The basic variety of the genus which just gets on with the job and 'says the black does the red' whatever it's accustomed usus. By far the most common in numbers but, unfortunately, the least influential.
(ii) Rainbow Plume (Liturgica phantasmata) Some authorities add synchrotistica to the sub genus name due to it's ability, when nesting, to beg borrow or steal from a wide variety of suprisingly innapropriate sources. Probably evolving in response largely to the external stimuli of it's unstable environment it is, surprisingly the most numerous. In a strange twist the female of the species seems to dominate in general day to day life.
(iii) Liveried Long Beak (Liturgica Machiavelliensis) Curious development of the species almost totally domesticated. It prefers to dwell indoors favouring long corridors. Not highly intelligent their diet over the years has departed from the common fodder of it's cousins with a distinct taste for sherry and rich food. It is, however, very pugnacious and any perceived threat or deviation from the 'norm' will be dealt with summarily by the pack. Because of this flaw in character it's unlikely to propogate itself beyond the current generation.
There is a danger that 'liturgy' may become an end in itself and we lose the Christocentric activity that it surely should be. When it becomes purely a careerist past time for the otherwise unemployable, when it becomes the field of battle for various ecclesiastics to settle scores and gain points against each other, we have a serious problem. It's not a modern 'thing' but a tension that has always been there. A reading of the first chapters of Christopher Page's excellent The Christian West and it's Singers gives plenty of food for thought. Self interest groups can become industries in their own right. Industries seem to amplify all the worst things human beings are capable of. This is the point where you can insert your own favourite 'liturgist' joke. The riddle in the title of this entry was formerly applied to lawyers.
