For we are not ignorant of his devices!
A part from the angels (bodiless hosts) there are demons. The Prophets, Apostles and Fathers have experience of this fact and describe the presence of demons. Appearances of demons are described throughout Holy Scripture, and St. John the Evangelist actually declares that the purpose of the Christ’s incarnation is that He might destroy the works of the devil, (i Jn 3:8).
The demons were originally angels, because God did not create evil, but through their pride they fell away from God’s glory and became demons. Christ said: I beheld Satan as lightning fall from heaven. (Lk 10:18). We shall draw attention to a few points that are relevant to the existence of the demons and their method of warfare.
As creatures of God and spirits, the demons are “ethereal beings,” but on account of their fall they do not participate in the glory of God as Light, so they are dark beings. All creation shares in the creative and sustaining energy of God, and this includes the demons. “Even the devil has a share in the uncreated energy of God,” that is to say, in His uncreated creative and sustaining energy; not in the glorifying energy of God but in the punitive energy.
