16 The gratuitous negation of the supernatural principles, proper to knowledge falsely so called , has actually become the postulate of a historical criticism equally false. Everything that relates in any way to the supernatural order, either as belonging to it, constituting it, presupposing it, or merely finding its explanation in it, is erased without further investigation from the pages of history. Such are the Divinity of Jesus Christ, His Incarnation through the operation of the Holy Ghost, His Resurrection by His own power, and in general all the dogmas of our faith. Science once placed on this false road, there is no law of criticism to hold it back; and it cancels at its own caprice from the holy books everything that does not suit it or that it believes to be opposed to the pre-established theses it wishes to demonstrate. For take away the supernatural order and the story of the origin of the Church must be built on quite another foundation, and hence the innovators handle as they list the monuments of history, forcing them to say what they wish them to say, and not what the authors of those monuments meant.
