"Moreover, they ratify and confirm all these with the powers of diverse Intelligences, through the sacred ceremonies of religions. The order and process of all these I shall endeavor to deliver in these three books: Whereof the first contains Natural Magic, the second Celestial, and the third Ceremonial. But I know not whether it be an unpardonable presumption in me, that I, a man of so little judgment and learning, should in my very youth so confidently set upon a business so difficult, so hard and intricate as this is. Wherefore, whatsoever things have here already, and shall afterward be said by me, I would not have anyone assent to them, nor shall I myself, any further than they shall be approved of by the universal church and the congregation of the faithful."
