Few men have watched the religious tendencies of the time with a keener eye than Cardinal Newman, and no man hated with a more intense hatred the latitudinarian tendencies which he witnessed. His judgment of their effect on the Establishment is very remarkable. In a letter to his friend Isaac Williams he says: 'Everything I hear makes me fear that latitudinarian opinions are spreading furiously in the Church of England. I grieve deeply at it. The Anglican Church has been a most useful breakwater against Scepticism. The time might come when you, as well as I, might expect that it would be said above, "Why cumbereth it the ground?" but at present it upholds far more truth in England than any other form of religion would, and than the Catholic Roman Church could. But what I fear is that it is _tending_ to a powerful Establishment teaching direct error, and more powerful than it has ever been; thrice powerful because it does teach error.'[60] It is, however, of course, evident that the latitude of opinion which may be reasonably claimed by the clergy of a Church encumbered with many articles and doctrinal formularies is not unlimited, and each man must for himself draw the line. The fact, too, that the Church is an Established Church imposes some special obligations on its ministers. It is their first duty to celebrate public worship in such a form that all members of the Church of England may be able to join in it. Whatever interpretations may be placed upon the ceremonies of the Church, those ceremonies, at least, should be substantially the same. A stranger who enters a church which he has never before seen should be able to feel that he is certain of finding public worship intelligibly and decently performed, as in past generations it has been celebrated in all sections of the Established Church. It has, in my opinion, been a gross scandal, following a gross neglect of duty, that this primary obligation has been defied, and that services are held in English churches which would have been almost unrecognisable by the churchmen of a former generation, and which are manifest attempts to turn the English public worship into an imitation of the Romish Mass. Men have a perfect right, within the widest limits, to perform what religious services and to preach what religious doctrines they please, but they have not a right to do so in an Established Church. The censorship of opinions is another thing, and in the conditions of English life it has never been very effectively maintained. The latitude of opinion granted in an Established Church is, and ought to be, very great, but it is, I think, obvious that on some topics a greater degree of reticence of expression should be observed by a clergyman addressing a miscellaneous audience from the pulpit of an Established Church than need be required of him in private life or even in his published books.
