Situation ethics has become the norm for our times, having replaced the biblical ethics of past generations. In situation ethics as long as no one is hurt one can do as one pleases. Taking drugs, watching pornography, and aborting the unborn child all can come under the flag of situation ethics.
Taking drugs is seen as morally neutral by increasing numbers of Americans. We believe no one is hurt by our drug use, while refusing to see the obvious connection between our drug purchases and the mass-killings in Mexico by drug cartels that are in the business because of the demand for drugs by American users.
Nothing wrong with watching pornography, we tell ourselves, forgetting that the demand for pornography enslaves many poor young women (and a few men) in a form of prostitution, all for our sexual gratification. Pornography has become one of the major addictions of our times, keeping large numbers of people in bondage and preventing sound, healthy relationships.
Situation ethics has convinced women that since they have the right to make decisions concerning their own bodies, aborting the fetus is allowable if their own lifestyle will be negatively affected. Nothing about the rights of the unborn, who have no voice whatsoever.
The Fathers knew that even the secret sins committed by people had an effect on the whole of the cosmos. The people who promote situation ethics would have us believe that nothing that is done in private hurts anyone. Biblical ethics tells us quite the opposite.
