"If ascetical theology depends upon an accepted doctrine of the Church as the Body of Christ, then Anglicanism fares no better than Protestantism. An equally varied body of opinion may be found in the ranks of the Church of England, but the significant difference is that, however abused, misused and misunderstood, Anglican ascetic is rooted in the Book of Common Prayer, which follows the universal pattern of Eucharist, Divine Office, personal devotion and habitual recollection, traceable through St Benedict to the New Testament. As an ascetical system the Book of Common Prayer presupposes the Catholic doctrine of the Church."
