To give a full explanation of the mystic passages of the Bible is contrary to the law and to reason; besides, my knowledge of them is based on reasoning, not on divine inspiration [and is therefore not infallible].... It is... possible that my view is wrong, and that I misunderstand passages referred to.... Those, however, for whom this treatise has been composed, will, on reflecting on it and thoroughly examining each chapter, obtain a clear insight into all that has been clear and intelligible to me. This is the utmost that can be done in treating this subject so to be useful to all without fully explaining it.
