5. I confess, however, that it reaches further than my purpose can carry me to inquire whether the angels, secretly working by the spiritual quality of their body abiding still in them, assume somewhat from the inferior and more bodily elements, which, being fitted to themselves, they may change and turn like a garment into any corporeal appearances they will, and those appearances themselves also real, as real water was changed by our Lord into real wine; or whether they transform their own bodies themselves into that which they would, suitably to the particular act. But it does not signify to the present question which of these it is. And although I be not able to understand these things by actual experience, seeing that I am a man, as the angels do who do these things, and know them better than I know them, viz., how far my body is changeable by the operation of my will; whether it be by my own experience of myself, or by that which I have gathered from others; yet it is not necessary here to say which of these alternatives I am to believe upon the authority of the divine Scriptures, lest I be compelled to prove it, and so my discourse become too long upon a subject which does not concern the present question.
