Of the Production of the Angels in the Order of Natural Being

After dealing with the nature of the angels, their knowledge and will, it now remains for us to treat of their creation, or, speaking in a general way, of their origin. Such consideration is threefold. In the first place we must see how they were brought into natural existence; secondly, how they were made perfect in grace or glory; and thirdly, how some of them became wicked.

Under the first heading there are four points of inquiry:

(1) Whether the angel has a cause of his existence?

(2) Whether he has existed from eternity?

(3) Whether he was created before corporeal creatures?

(4) Whether the angels were created in the empyrean heaven?
