The purpose of this post is to confront those Christians who are of the opinion that they can be Marxists and Christians; that is not possible. The following two very brief videos provide instruction in logic that the human rational mind uses every day; although most do not notice the processes happening. The same topic, described by two different teachers in two different settings should help readers understand why a person cannot simultaneously be an atheist and a theist – cannot be both a Marxist and a Christian.
