The controversy which had sprung up at home showed that a book written as this one had been begun would be frequently misunderstood. In that controversy it was often taken for granted that when an Ultramontane disclaims Temporal Power, he disclaims power over temporal things; and that when he writes Spiritual Power, he means only power over spiritual things; that when he writes Religious Liberty, he means freedom for every one to worship God according to his conscience; that when he writes the Divine Law, he means only the Ten Commandments and the precepts of the Gospel; that when he writes the Kingdom of God, he means righteousness and peace and joy in the Holy Ghost; and that when he writes the Word of God, he simply means the Bible. One reasoning with false interpretations like these in his mind must reason in such a fog as Dr. Newman, in his letter to the Duke of Norfolk, cleverly depicts. Ambiguity similar to that now indicated prevails over the whole field of phraseology--theological, political, and educational. English Ultramontanes are doubtless in part responsible for these misapprehensions, but only in part. If their writings are _studied_, they will be seen to use such terms differently from their fellow-countrymen. But certainly the Papal Press of Rome, and even that of France, is not in any degree responsible for our illusions, but has, on the contrary, left us without excuse. The consequence of all this is that in this book, where a mere allusion would have been made, a fact is now often related; where the sense of some particular utterance would have been condensed, that utterance is verbally recited; and where one sentence would have been culled out, more are given. Very often, where a statement of the principles of the Papal movement would have been accompanied only by a reference to a contemporary authority, that authority is made to speak for himself, and occasionally at some length. Terms and phrases, which might have been left to the chance of being understood, are either coupled with narratives or discussions, to bring out their sense, or else they are explained. When I do give explanations, let me not be trusted, but watched. Much will be found of the language both of Catholics and of Liberal Catholics, and with it the reader can confront my strange-looking explanations. In the end he will be able to do what, thank God, every Englishman is inclined to do--form an opinion for himself as to the real sense in which the speakers employed their own words.
