This address was delivered by the late Dr. Schaeffer in 1982 and is from his book: A Christian Manifesto. This is quite lengthy but worth reading.
Christians, in the last 80 years or so, have only been seeing things as bits and pieces which have gradually begun to trouble them and others, instead of understanding that they are the natural outcome of a change from a Christian World View to a Humanistic one; things such as overpermissiveness, pornography, the problem of the public schools, the breakdown of the family, abortion, infanticide (the killing of newborn babies), increased emphasis upon the euthanasia of the old and many, many other things.
All of these things and many more are only the results. We may be troubled with the individual thing, but in reality we are missing the whole thing if we do not see each of these things and many more as only symptoms of the deeper problem. And that is the change in our society, a change in our country, a change in the Western world from a Judeo-Christian consensus to a Humanistic one. That is, instead of the final reality that exists being the infinite creator God; instead of that which is the basis of all reality being such a creator God, now largely, all else is seen as only material or energy which has existed forever in some form, shaped into its present complex form only by pure chance.
