Its more 'official' heads are the two Archbishops, those of Canterbury and York. With Canterbury, I believe, outranking York. There is a hierarchy that one must pass through to become an official priest in the Church of England, and wear a dog collar and a cassock and everything, that involves becoming a Deacon somewhere along the line, and making vows stating that you won't smoke pot in church or practise drawing pentagrams in the backs of the hymn books.
The service for a C of E Eucharist used to be very beautiful to listen to, with a lot of old language and some lovely music... Unfortunately, time marches on. The service has been 'modernised', the language is no longer pleasantly old, the Kyrie eleison and others are no longer sung in the church I attend from time to time (I'm an atheist, but I go to give my friend the Crucifer moral support and to have people scream 'Demon' at me). Perhaps this is a good thing. Perhaps the idea of a service more acceptable and accessible justifies the wholesale destruction of a work of verbal art.
