Whether charity is lost through one mortal sin?

❌ Objection 1 : It would seem that charity is not lost through one mortal sin. For Origen says (Peri Archon i): "When a man who has mounted to the stage of perfection, is satiated, I do not think that he will become empty or fall away suddenly; but he must needs do so gradually and by little and little." But man falls away by losing charity. Therefore charity is not lost through only one mortal sin.

❌ Objection 2 : Further, Pope Leo in a sermon on the Passion (60) addresses Peter thus: "Our Lord saw in thee not a conquered faith, not an averted love, but constancy shaken. Tears abounded where love never failed, and the words uttered in trepidation were washed away by the fount of charity." From this Bernard [*William of St. Thierry, De Nat. et Dig. Amoris. vi.] drew his assertion that "charity in Peter was not quenched, but cooled." But Peter sinned mortally in denying Christ. Therefore charity is not lost through one mortal sin.

❌ Objection 3 : Further, charity is stronger than an acquired virtue. Now a habit of acquired virtue is not destroyed by one contrary sinful act. Much less, therefore, is charity destroyed by one contrary mortal sin.

❌ Objection 4 : Further, charity denotes love of God and our neighbor. Now, seemingly, one may commit a mortal sin, and yet retain the love of God and one's neighbor; because an inordinate affection for things directed to the end, does not remove the love for the end, as stated above (Article [10]). Therefore charity towards God can endure, though there be a mortal sin through an inordinate affection for some temporal good.

❌ Objection 5 : Further, the object of a theological virtue is the last end. Now the other theological virtues, namely faith and hope, are not done away by one mortal sin, in fact they remain though lifeless. Therefore charity can remain without a form, even when a mortal sin has been committed.
