We next consider the degrees of the angels in their hierarchies and orders; for it was said above ( Q , A ), that the superior angels enlighten the inferior angels; and not conversely.
Under this head there are eight points of inquiry:
A Whether all the angels belong to one hierarchy?
A Whether in one hierarchy there is only one order?
A Whether in one order there are many angels?
A Whether the distinction of hierarchies and orders is natural?
A Of the names and properties of each order.
A Of the comparison of the orders to one another.
A Whether the orders will outlast the Day of Judgment?
A Whether men are taken up into the angelic orders?
