Whether faith has the effect of purifying the heart?

❌ Objection 1 : It would seem that faith does not purify the heart. For purity of the heart pertains chiefly to the affections, whereas faith is in the intellect. Therefore faith has not the effect of purifying the heart.

❌ Objection 2 : Further, that which purifies the heart is incompatible with impurity. But faith is compatible with the impurity of sin, as may be seen in those who have lifeless faith. Therefore faith does not purify the heart.

❌ Objection 3 : Further, if faith were to purify the human heart in any way, it would chiefly purify the intellect of man. Now it does not purify the intellect from obscurity, since it is a veiled knowledge. Therefore faith nowise purifies the heart.
