Acritic suggested that Dom Gregory Dix in his monumental The Shape of the Liturgy had some brilliant liturgical intuitions, even though he was not always accurate or Profound in his details. This criticism may or may not be justified of the book as a whole; but there was surely a brilliancy of intuition in Fr Dix's treatment of St Cyril of Jerusalem and his relation to the development of the liturgy in the West as well as in the East. The realisation that St Cyril introduced a new type of symbolism into the universal prayer of the Church was surely something of a discovery and all its implications may not have been fully appreciated even by Fr Dix himself. At all events, it may be useful to summarise his discovery for the benefit of those unacquainted with this book, and to point to one important implication which bears upon the whole question of the way Christian men express themselves in prayer together.
