“ Further, every holy angel is nearer to God than Satan is. Yet Satan assisted God, according to Job 1:6: "When the sons of God came to stand before the Lord, Satan also was present among them." Therefore much more do the angels, who are sent to minister, assist.
Objection 4: Further, if the inferior angels do not assist, the reason is because they receive the Divine enlightenment, not immediately, but through the superior angels. But every angel receives the Divine enlightenment from a superior, except the one who is highest of all. ”

“ It may also be said that the superior angels communicate their own proper gifts whereby they are denominated, through the ministry of the inferior angels. Thus one of the Seraphim is described as purifying by fire the prophet's lips, not as if he did so immediately, but because an inferior angel did so by his power; as the Pope is said to absolve a man when he gives absolution by means of someone else. ”

“ This explanation rests on the opinion of the Platonists, who said that the nearer things are to the one first principle, the smaller they are in number; as the nearer a number is to unity, the lesser it is than multitude. ”

“ That the man born blind was enlightened, that Lazarus was raised from the dead, was accomplished immediately by God without the action of the heavenly bodies. Moreover both good and bad angels can work some effect in these bodies independently of the heavenly bodies, by the condensation of the clouds to rain, and by producing some such effects. Nor can anyone doubt that God can immediately reveal things to men without the help of the angels, and the superior angels without the inferior. ”

“ Satan is not described as having assisted, but as present among the assistants; for, as Gregory says (Moral. ii) , "though he has lost beatitude, still he has retained a nature like to the angels."
Reply to Objection 4: All the assistants see some things immediately in the glory of the Divine Essence; and so it may be said that it is the prerogative of the whole of the highest hierarchy to be immediately enlightened by God; while the higher ones among them see more than is seen by the inferior ”

“ Dionysius, however, (Coel. Hier. xiv) declares that the multitude of angels surpasses all the multitude of material things; so that, as the superior bodies exceed the inferior in magnitude to an immeasurable degree, so the superior incorporeal natures surpass all corporeal natures in multitude; because whatever is better is more intended and more multiplied by God. Hence, as the assistants are superior to the ministers there will be more assistants than ministers. ”
