Whether God is the cause of spiritual blindness and hardness of heart?
Objections
❌ Objection 1 : It would seem that God is not the cause of spiritual blindness and hardness of heart. For Augustine says (Qq. lxxxiii, qu. 3) that God is not the cause of that which makes man worse. Now man is made worse by spiritual blindness and hardness of heart. Therefore God is not the cause of spiritual blindness and hardness of heart.
❌ Objection 2 : Further, Fulgentius says (De Dupl. Praedest. i, 19): "God does not punish what He causes." Now God punishes the hardened heart, according to Ecclus. 3:27: "A hard heart shall fear evil at the last." Therefore God is not the cause of hardness of heart.
❌ Objection 3 : Further, the same effect is not put down to contrary causes. But the cause of spiritual blindness is said to be the malice of man, according to Wis. 2:21: "For their own malice blinded them," and again, according to 2 Cor. 4:4: "The god of this world hath blinded the minds of unbelievers": which causes seem to be opposed to God. Therefore God is not the cause of spiritual blindness and hardness of heart.
