One of the popular ideas of mankind is this idea that morals are relative. That what is considered acceptable moral behavior is determined by the dominant culture. This idea that what is considered morally acceptable is determined by culture and society is called Moral Relativism or just Relativism.
The arguments often point to standards such as the Ten Commandments as antiquated and not relevant to modern society. They will call the moral standards of past generations "old fashioned". They argue that society has evolved and that the moral standards must change in our changing world.
Now here is the fundamental problem with this view. First off, part of the reason this mode of thinking has become popular is because everyone is trying to be politically correct. No one wants to offend anyone. Those that do not meet the moral standards of one society do not want to feel inferior. They want to feel better about themselves regardless of their conduct.
Secondly, they want to justify how different cultures view the world without coming to a conclusion that some cultures are better than others in a moral sense. So by making morality a flexible matter of opinion, they can justify all kinds of things by simply stating that it is acceptable in that culture.
The problem with this view is that right and wrong are in fact quite concrete. There are hard fast laws of the universe, and if these laws are either kept or broken certain consequences result. Our point of view does not alter the end results. While it is true that some forbearance is due, ultimately the eternal truths are always true, and either we find ourselves in compliance with those truths or we do not.
One example is found in today's society. The culturally accepted rules for dating, dress standards, language standards, etc. have changed dramatically from what they were say one hundred years ago. The relativist will state that because society has changed, then the new standards are not morally inferior to the previous standards. But the hard facts have not changed, and these lowered social standards have played a major part in the decay of our society. The natural consequences of these changes is an absolute. As the moral standards of the society degrade relative to the moral truth, the result is: indulgence, increased selfishness, debt, weaker relationships, increased abuse, corruption, promiscuity, reduced scholastic achievement, laziness, a sense of entitlement, etc. No matter what the society considers acceptable, the breaking of eternal laws produces certain natural consequences. Likewise, if society increases its moral standards, various blessings naturally result.
My point is that morality needs to be based upon the truth, not culturally relative ideas. The bible contains and teaches these truths. It happens that a loving God
