Summa Theologica

By Thomas Aquinas

OF THE CAUSE OF PROPHECY (SIX ARTICLES)

We must now consider the cause of prophecy. Under this head there are six points of inquiry:

(1) Whether prophecy is natural?

(2) Whether it is from God by means of the angels?

(3) Whether a natural disposition is requisite for prophecy?

(4) Whether a good life is requisite?

(5) Whether any prophecy is from the demons?

(6) Whether prophets of the demons ever tell what is true?
