Whether all the angels who are sent, assist?

Objections

Objection 1 : It would seem that the angels who are sent also assist. For Gregory says (Hom. xxxiv in Evang.): "So the angels are sent, and assist; for, though the angelic spirit is limited, yet the supreme Spirit, God, is not limited."
Objection 2 : Further, the angel was sent to administer to Tobias. Yet he said, "I am the angel Raphael, one of the seven who stand before the Lord" (Tob. 12:15). Therefore the angels who are sent, assist.
Objection 3 : 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. Therefore only the highest angel would assist; which is contrary to the text of Dan. 7:10: "Ten thousand times a hundred thousand stood before Him." Therefore the angels who are sent also assist.
