Aquinas’ followers, commonly referred to as the Thomists, accused the Ockhamists of Pelagianism for basing the infusion of grace on man's works. The Ockhamists defended themselves from charges of Pelagianism by arguing that, in the Ockhamist system, God was not bound to award the infusion of grace on the basis of congruent merit; rather, God's decision to award the infusion of grace on the basis of congruent merit was an entirely gracious act on God's part.
