Whether original sin is a habit?

❌ Objection 1 : It would seem that original sin is not a habit. For original sin is the absence of original justice, as Anselm states (De Concep. Virg. ii, iii, xxvi), so that original sin is a privation. But privation is opposed to habit. Therefore original sin is not a habit.

❌ Objection 2 : Further, actual sin has the nature of fault more than original sin, in so far as it is more voluntary. Now the habit of actual sin has not the nature of a fault, else it would follow that a man while asleep, would be guilty of sin. Therefore no original habit has the nature of a fault.

❌ Objection 3 : Further, in wickedness act always precedes habit, because evil habits are not infused, but acquired. Now original sin is not preceded by an act. Therefore original sin is not a habit.
