And as the Gentiles did vulgarly conceive the Imagery of the brain, for things really subsistent without them, and not dependent on the fancy; and out of them framed their opinions of Daemons, Good and Evill; which because they seemed to subsist really, they called Substances; and because they could not feel them with their hands, Incorporeall:  so also the Jews upon the same ground, without any thing in the Old Testament that constrained them thereunto, had generally an opinion, (except the sect of the Sadduces,) that those apparitions (which it pleased God sometimes to produce in the fancie of men, for his own service, and therefore called them his Angels) were substances, not dependent on the fancy, but permanent creatures of God; whereof those which they thought were good to them, they esteemed the Angels of God, and those they thought would hurt them, they called Evill Angels, or Evill Spirits; such as was the Spirit of Python, and the Spirits of Mad-men, of Lunatiques, and Epileptiques:  For they esteemed such as were troubled with such diseases, Daemoniaques.

But if we consider the places of the Old Testament where Angels are mentioned, we shall find, that in most of them, there can nothing else be understood by the word Angel, but some image raised (supernaturally) in the fancy, to signifie the presence of God in the execution of some supernaturall work; and therefore in the rest, where their nature is not exprest, it may be understood in the same manner.

For we read Gen. 16. that the same apparition is called, not onely an Angel, but God; where that which (verse 7.) is called the Angel of the Lord, in the tenth verse, saith to Agar, “I will multiply thy seed exceedingly;” that is, speaketh in the person of God.  Neither was this apparition a Fancy figured, but a Voice.  By which it is manifest, that Angel signifieth there, nothing but God himself, that caused Agar supernaturally to apprehend a voice supernaturall, testifying Gods speciall presence there.  Why therefore may not the Angels that appeared to Lot, and are called Gen. 19.13.  Men; and to whom, though they were but two, Lot speaketh (ver. 18.) as but one, and that one, as God, (for the words are, “Lot said unto them, Oh not so my Lord”) be understood of images of men, supernaturally formed in the Fancy; as well as before by Angel was understood a fancyed Voice?  When the Angel called to Abraham out of heaven, to stay his hand (Gen. 22.11.) from slaying Isaac, there was no Apparition, but a Voice; which neverthelesse was called properly enough a Messenger, or Angel of God, because it declared Gods will supernaturally, and saves the labour of supposing any permanent Ghosts.  The Angels which Jacob saw on the Ladder of Heaven (Gen. 28.12.) were a Vision of his sleep; therefore onely Fancy, and a Dream; yet being supernaturall, and signs of Gods Speciall presence, those apparitions are not improperly called Angels.  The same is to be understood (Gen.31.11.) where Jacob saith thus, “The Angel of the Lord appeared to mee in my sleep.”  For an apparition made to a man in his sleep, is that which all men call a Dreame, whether such Dreame be naturall, or supernaturall:  and that which there Jacob calleth an Angel, was God himselfe; for the same Angel saith (verse 13.) “I am the God of Bethel.”
