12 Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all people, because all sinned
13 To be sure, sin was in the world before the law was given, but sin is not charged against anyones account where there is no law. 14 Nevertheless, death reigned from the time of Adam to the time of Moses, even over those who did not sin by breaking a command, as did Adam, who is a pattern of the one to come.
That describes original sin we inherit from Adam, and Christ cleanses. This does not describe, or contradict, the makeup of man in the divine image.
While on this topic: one must distinguish evil inclinations, such as homosexual attraction, or propensity to alcoholism, or broken concept of dignity of man. These are very unfortunate, but they are not yet sin. They become sin when a homosexual act is committed, or drunkenness takes over a life, or a murder occurs. It is the job of schools to steer young people away from evil inclinations they may have before they become actual sins. The problem with anti-bullying campaign is not that it, on its face, calls for mutual respect among the children, but that it, combined with the prevailing culture, confirms homosexuality as a lifestyle choice and teaches that that choice — rather than the man erring in his choice, — needs to be respected. That is what is evil about it. However, the fundamental evil of American schools is not that they are places where sexual deviance is promoted, — they are that, but that is merely a consequence. The fundamental evil of American schools is that they do not teach Christianity. It is not more complicated than that.
