TENTH ARTICLE [I, Q. 19, Art. 10]

Whether God Has Free-Will?

Objection 1: It seems that God has not free-will. For Jerome says, in

a homily on the prodigal son [*Ep. 146, ad Damas.]; "God alone is He

who is not liable to sin, nor can be liable: all others, as having

free-will, can be inclined to either side."

Obj. 2: Further, free-will is the faculty of the reason and will, by

which good and evil are chosen. But God does not will evil, as has

been said (A. 9). Therefore there is not free-will in God.

_On the contrary,_ Ambrose says (De Fide ii, 3): "The Holy Spirit

divideth unto each one as He will, namely, according to the free

choice of the will, not in obedience to necessity."

_I answer that,_ We have free-will with respect to what we will not of

necessity, nor by natural instinct. For our will to be happy does not

appertain to free-will, but to natural instinct. Hence other animals,

that are moved to act by natural instinct, are not said to be moved by

free-will. Since then God necessarily wills His own goodness, but

other things not necessarily, as shown above (A. 3), He has free

will with respect to what He does not necessarily will.

Reply Obj. 1: Jerome seems to deny free-will to God not simply, but

only as regards the inclination to sin.

Reply Obj. 2: Since the evil of sin consists in turning away from the

divine goodness, by which God wills all things, as above shown, it is

manifestly impossible for Him to will the evil of sin; yet He can

make choice of one of two opposites, inasmuch as He can will a thing

to be, or not to be. In the same way we ourselves, without sin, can

will to sit down, and not will to sit down.
