I think, however, the changes that have taken place have not altered the essential character of the Roman Church. I think the changes that have happened are in conformity with the nature of that church; really were to be expected, and have nothing absolutely new in them. We might, perhaps, for a long time have seen them coming; and, if we had had foresight enough, we might have seen them from the very first times of that church. Let us try to understand exactly what she is, what she means; let us try to see what there is under that name, "Roman Catholic Church." She calls herself _catholic_, which means _universal_, and at the same time she has a local name. She is for the whole world; but at the same time she belongs to one city, and she bears the name of that city. Why? This is the question; and though it seems only a question of name, I think we shall find by other ways that it is a question of facts. A second advance requires a change in our polemics with Roman authority. A new science has been created in our time, which gives us better means of judging and studying other churches than our own; that science is called the comparative history of religions. In England Max Müller, in France Burnouf, and in this country James Freeman Clarke, have compared the history of several religions. According to that comparative history, there are rules to be understood, to be acknowledged, in the development of religion. One of the rules which I think we can deduce from any comparative history of religion may be a startling one; and I will use a very homely comparison, to make myself perfectly understood. Have you ever seen over a shop door a sign-board, where the name of the old shop-keeper was painted; and, when his successor came in, he had the same board covered with a new color, and his own name painted over the old one? But in time the new paint wore off, so that the old name reappeared under the new, in such a way that it became perhaps difficult to distinguish clearly which letters or lines belonged to the old, and which to the new. If this image appears somewhat too familiar, let me ask you if you remember what scholars call a palimpsest. Sometimes in the Middle Ages it was difficult to find well-prepared parchment on which to write, and there were a great many monks who had nothing else to do--and it was the best use they could make of their time--but write or copy the Bible or other religious books. When they found parchments where were copied the comedies and tragedies or other works of the heathen, they thought those were of very little use, and they could very easily have the writing on those parchments washed out, or covered over with white paint, in such a way that what had been written there was no more visible. Then on those parchments they would write the Bible, or sermons, or any document they thought useful. But the same thing happened then that happened with the
