Sin corrupts every institution and every system because, one way or another, sinful human beings are involved. This means that laws, policies, habits, and customs are also corrupted by sin. We are called to do everything within our power to expunge sin from the structures of our society. Christians know that the justice of God demands that we do so. At the same time, we cannot accept that the structural manifestations of sin are the heart of the problem. No, the heart of the problem is found in the sinfulness of the individual human heart.
