But lastly there is another appeal which men make in this day. We are now told that scientific history is the test of truth; and I saw the other day in a document having great pretension from a certain body of men who are troubling Germany and attempting to trouble even England with the name of Old Catholics, that the way to know the pure faith of Jesus Christ is to interpret history by science. Alas, as I said before, the world is full of pretensions to science; but those who claim to be Catholics, and who yet appeal from the living voice of the Catholic Church to any other tribunal whatsoever, are all of them identical in their principle, and that principle is heresy. Luther appealed from the voice of the Catholic Church to Scripture, and thereby became a heretic. There are others who appeal to antiquity, and the appeal is the same--it is an appeal from the living voice, from the divine authority of the Church, to something of their own choice and creation. It matters not to what the appeal is made. That which constitutes both the treason of the act and the heresy of the principle is that they appeal from the living voice, that is from the divine voice. This it is that is being done at this moment by a body of men who profess to be and to intend to live and die Catholics; and what is more, to purify and reform the Church by staying in it. What is their appeal? Their appeal is to history, to scientific history; that is, to history interpreted by themselves. Luther was much more direct and much wiser. He appealed to a book which is certainly written by the Holy Ghost; they appeal to I know not what books, but to books certainly written only by men, and not by the Spirit of God; to human history, the authenticity of which and the purity of the text of which no one can guarantee; and even this they interpret for themselves.
