Whether wisdom can be without grace, and with mortal sin?

Objections

Objection 1 : It would seem that wisdom can be without grace and with mortal sin. For saints glory chiefly in such things as are incompatible with mortal sin, according to 2 Cor. 1:12: "Our glory is this, the testimony of our conscience." Now one ought not to glory in one's wisdom, according to Jer. 9:23: "Let not the wise man glory in his wisdom." Therefore wisdom can be without grace and with mortal sin.
Objection 2 : Further, wisdom denotes knowledge of Divine things, as stated above (Article [1]). Now one in mortal sin may have knowledge of the Divine truth, according to Rm. 1:18: "(Those men that) detain the truth of God in injustice." Therefore wisdom is compatible with mortal sin.
Objection 3 : Further, Augustine says (De Trin. xv, 18) while speaking of charity: "Nothing surpasses this gift of God, it is this alone that divides the children of the eternal kingdom from the children of eternal perdition." But wisdom is distinct from charity. Therefore it does not divide the children of the kingdom from the children of perdition. Therefore it is compatible with mortal sin.
