Angels were created by God--They were created immediately by Him--They were created in the Empyrean sky--They were created in grace--They were created in imperfect beatitude. After a severe chain of reasoning, he shows that angels are incorporeal compared to us, but corporeal compared to God. An angel is composed of action and potentiality; the more superior he is, he has the less potentiality. They have not matter properly. Every angel differs from another angel in species. An angel is of the same species as a soul. Angels have not naturally a body united to them. They may assume bodies; but they do not want to assume bodies for themselves, but for us. The bodies assumed by angels are of thick air. The bodies they assume have not the natural virtues which they show, nor the operations of life, but those which are common to inanimate things. An angel may be the same with a body. In the same body there are, the soul formally giving being, and operating natural operations; and the angel operating supernatural operations. Angels administer and govern every corporeal creature. God, an angel, and the soul, are not contained in space, but contain it. Many angels cannot be in the same space. The motion of an angel in space is nothing else than different contacts of different successive places. The motion of an angel is a succession of his different operations. His motion may be continuous and discontinuous as he will. The continuous motion of an angel is necessary through every medium, but may be discontinuous without a medium. The velocity of the motion of an angel is not according to the quantity of his strength, but according to his will. The motion of the illumination of an angel is threefold, or circular, straight, and oblique. In this account of the motion of an angel we are reminded of the beautiful description of Milton, who marks it by a continuous motion, "Smooth-sliding without step." The reader desirous of being _merry_ with Aquinas's angels may find them in Martinus Scriblerus, in Ch. VII. who inquires if angels pass from one extreme to another without going through the _middle_? And if angels know things more clearly in a morning? How many angels can dance on the point of a very fine needle, without jostling one another?
