According to canon 1220 of the Catholic church’s code of canon law, ‘all those responsible are to take care that in churches such cleanliness and beauty are preserved as befit a house of God and that whatever is inappropriate to the holiness of the place is excluded’. So, if Canterbury cathedral were still Catholic, as it was for 900 years before the discordant event of the Reformation, it is fair to say that the ghost of Thomas Becket would not have been disturbed by the rave in the nave which took place last night and is repeated tonight.
