Whether all the angels of the second hierarchy are sent?

Objections

Objection 1 : It would seem that all the angels of the second hierarchy are sent. For all the angels either assist, or minister, according to Dan. 7:10. But the angels of the second hierarchy do not assist; for they are enlightened by the angels of the first hierarchy, as Dionysius says (Coel. Hier. viii). Therefore all the angels of the second hierarchy are sent in ministry.
Objection 2 : Further, Gregory says (Moral. xvii) that "there are more who minister than who assist." This would not be the case if the angels of the second hierarchy were not sent in ministry. Therefore all the angels of the second hierarchy are sent to minister.
