Abstract

In this article I argue against some contemporary scholars that Thomas Aquinas holds that grace is in some way necessary for the perfection of even natural virtue, due to original sin. First I show that healing grace is necessary for the fulfillment of ordinary natural moral duties. On account of original sin, human cannot fulfill the precept to naturally love God without healing grace. Moreover, they cannot avoid committing some acts (mortal sins) whereby they are turned away from God. Second, I argue that without grace someone cannot acquire the political virtues (acquired moral virtues) that make the agent good even on a natural level, and are connected with each other through prudence.
