The Action of the Angels on Man

We now consider the action of the angels on man, and inquire: (1) How far they can change them by their own natural power; (2) How they are sent by God to the ministry of men; (3) How they guard and protect men.

Under the first head there are four points of inquiry:

(1) Whether an angel can enlighten the human intellect?

(2) Whether he can change man's will?

(3) Whether he can change man's imagination?

(4) Whether he can change man's senses?
