By Dr. Donald DeMarco, Catholic Exchange - In 1973, the internationally distinguished psychiatrist, Karl Menninger, wrote a book entitled, Whatever Became of Sin. He predicted that the time would come when people no longer believed that there is such a thing as sin. With the growth of humanism and the decline of religion, people would excuse their immorality by blaming their biology, their upbringing, their associates, or even the environment. There would, therefore, be no need for forgiveness since what was formerly known as a sin would be rationalized away.
