congruous (if lacking detail) with the symptoms of modern leprosy, but the relationship between this disease, tzaraath, and Hansen's disease has been disputed. The biblical perception that people with leprosy were unclean can be found in a passage from Leviticus 13: 44–46. While this text defines the leper as impure, it did not explicitly make a moral judgement on those with leprosy. Some Early Christians believed that those affected by leprosy were being punished by God for sinful behavior. Moral associations have persisted throughout history. Pope Gregory the Great (540–604) and Isidor of Seville (560–636) considered people with the disease to be heretics. Middle Ages The social perception of leprosy in the general population was in general mixed. On one hand, people feared getting infected with the disease and thought of people suspected of leprosy to be unclean, untrustworthy, and occasionally morally corrupt. On the other hand, Jesus' interaction with lepers, the writing of church leaders and the Christian focus on charitable works led to viewing the lepers as "chosen by God" or seeing the disease as a means of obtaining access to heaven. Early medieval understanding of leprosy was influenced by early Christian writers such as Gregory of Nazianzus and John Chrysostom, whose writings were later embraced by Byzantine and Latin writers. Gregory, for example, did not only compose sermons urging Christians to assist victims of the disease, but also condemned pagans or Christians who justified rejecting lepers on the allegation that God had sent them the disease to punish them. As cases of leprosy increased during these years in the Eastern Roman Empire, becoming a major health issue, the ecclesiastic leaders of the time discussed how to assist those affected as well as change the attitude of society towards them. They also tried this by using the name "Holy disease" instead of the commonly used "Elephant's disease" (elephantiasis), implying that God did not create this disease to punish people but to purify them for heaven. Although not always successful in persuading the public and a cure was never found by Greek medicians, they created an environment where victims could get palliative care and were never expressly banned from society, as sometimes happened in Western Europe. Theodore Balsamon, a 12th century jurist in Constantinople, noted that lepers were allowed to enter the same churches, cities and assemblies that healthy people attended. As the disease became more prevalent in Western
