(CG 1/084). That the Will of God is not of things in themselves Impossible (Book 1: Of God As He Is In Himself) (Summa Contra Gentiles) (Aquinas, Thomas, St.)

HYPOTHETICAL necessity in the cause cannot lead to absolute necessity in the effect. But God's will about a creature is not absolutely necessary, but hypothetically so (Chap. LXXXIII). Therefore the divine will is no argument of absolute necessity in creatures. But only this absolute necessity excludes contingency: for even a contingent fact may be extended either way into an hypothetical necessity: thus it is necessary that Socrates moves, if he runs. It does not therefore follow that a thing happens of necessity, if God wills it: all that holds is the necessary truth of this conditional: 'If God wills anything, the thing will be': but the 'consequent' (as distinguished from the 'consequence') need not be a necessary truth.
