Prophets by the Holy Ghost: and seeing all tongues have, and do undergo various mutations, and corruptions, this alone doth alwaies continue inviolated. Moreover an evident sign of this opinion is, that though each Demon, and Intelligence do use the speech of those nations, with whom they do inhabit, yet to them that understand it, they never speak in any Idiome, but in this alone. But now how Angels speak it is hid from us, as they themselves are. Now to us that we may speak, a tongue is necessary with other instruments, as are the jaws, palate, lips, teeth, throat, lungs, the aspera arteria, and muscles of the breast, which have the beginning of motion from the soul. But if any speak at a distance to another, he must use a louder voice; but if neer, he whispers in his ear: and if he could be coupled to the hearer, a softer breath would suffice; for he would slide into the hearer without any noise, as an image in the eye, or glass. So souls going out of the body, so Angels, so Demons speak: and what man doth with a sensible voyce, they do by impressing the conception of the speech in those to whom they speak, after a better manner then if they should express it by an audible voyce. So the Platonists say that Socrates perceived his Demon by sense indeed, but not of this body, but by the sense of the etheriall body concealed in this: after which manner Avicen believes the Angels were wont to be seen, and heard by the Prophets: That instrument, whatsoever the vertue be, by which one spirit makes known to another spirit what things are in his minde, is called by the Apostle Paul the tongue of Angels. Yet oftentimes also they send forth an audible voyce, as they that cryed at the ascension of the Lord, Ye men of Galile, why stand ye there gazing into the heaven? And in the old law they spake with divers of the Fathers with a sensible voyce, but this never but when they assumed bodies. But with what senses those spirits and Demons hear our invocations, and prayers, and see our ceremonies, we are altogether ignorant.
For there is a spirituall body of Demons everywhere sensible by nature, so that it toucheth, seeth, heareth, without any medium,
