"This Protestant fifth column is still with us. Declarations are constantly being made that the Church of England comprehends many points of view and that all of them have an equal right to exist within its borders. We are told that extreme "Evangelical" Churches are as much "Church of England" as "Anglo-Catholic" ones, perhaps even more so. But this is simply not true. This is proved by the one authoritiative document which the Church of England has issued -- the Book of Common Prayer. Doctrines which are contrary to it are disloyal. Churches which do not obey its directions represent disloyal and rebellious elements."
J. C. L. Dart, The Old Religion
But it is equally true that churches, priests and bishops who imitate the Church of Rome either in doctrine or ceremonial are equally disloyal. I am in the process of reading The Very Rev'd Vernon Staley's Studies in Ceremonial and he made it very clear that most of what those who call themselves Anglo-Catholics are not only being disloyal to the basic Anglican position, but to that of the whole Western Church before the Council of Trent. Look to see some of his work on this blog.
