It is not surprising that the secular media and secular society have rejected the term sin. Instead, they have interpreted evil and misbehavior as sickness or mental illness. This has come about due to the fact that many who have rejected God's Word and the Bible's pronouncement upon human sin needed to substitute something for the problems of people. Secular thinking teaches that people are basically good.
Evil is, therefore, an aberration, a disease, a mistake.
As a result of rejecting the Bible's teaching that people are basically sinful and self-centered we have a society that is at a loss to adequately explain or deal with the human condition. It is one thing to deal with a secular society that rejects sin. It is quite another matter when we find the Church of Jesus Christ doing the same thing. Instead of acknowledging that the Bible says such choices and behavior are sinful, too many pastors and church leaders have succumbed to secular interpretation of these things. The end result is that some theologians and pastors have done Biblical gymnastics getting the text to agree with their current ideas.
