In the mid-1960's, a major shift occured in the church. Instead of calling sinful behavior "sin", it was labeled "sickness". The sexual sinner Paul wrote about (1 Corinthians 6:9) became the sex addict. The drunkard (1 Corinthians 6:9) became an alcoholic. The rebellious child (2 Corinthians 6:10) became afflicted with "Oppositional Defiant Disorder." The "deeds of the flesh, which are immorality, impurity, sensuality, idolatry" and so on (Galatians 5:19-21) have all been redefined using psychopathological words.
Now instead of seeking God's defintions and explanations of human behavior, more and more people are accepting a secular worldview based on humanistic psychology rather than the Bible.
