John Thompson describes how Martin Luther and John Calvin treated conscience. For Luther, natural conscience is beset by knowing that a person can never meet the rigorous requirements of the law. Faith can relieve a person’s downtrodden conscience, which would otherwise condemn him. Once a person accepts the favor of God that flows solely from trusting him, his conscience is liberated. He knows he can do nothing himself to merit that favor. His conscience is freed “to trust God’s promise of mercy and forgiveness.” The highest functioning conscience for Luther, then, is the one that does not depend on its own goodness or perfection. Calvin teaches that, though a person’s conscience is a natural faculty, it is marred and affected by the fall. Once a person is saved, however, his conscience is transformed so that he desires to obey the will of God found in the law. This is true even though adherence to the law will not add in the least to his salvation. For this reason, Calvin created a catechism to train and chasten Genevan Christians’ consciences. Calvin also helped to establish the Geneva consistory, which was less a disciplinary body, and rather “a school for consciences.”
