Right and Wrong … who decides?
The World Book Encyclopedia states: “One of humanity’s special traits is to ask thoughtful questions about what we should or should not do.”
God's word or man's.
Once upon a time God’s word, the Bible, influenced many societies. Today humanism, secularism and freethinking are the influences.
Today is to be tolerant, not judgmental. Everything is considered relative; there is no longer any absolute in right and wrong.

“Look out: perhaps there may be someone who will carry you off as his prey through the philosophy and empty deception according to the tradition of men, according to the elementary things of the world and not according to Christ.”
Colossians 2:8
19 For it is written: “I will make the wisdom of the wise men perish, and the intelligence of the intellectuals I will reject.”*+ 20 Where is the wise man? Where is the scribe? Where is the debater of this system of things? Has not God made the wisdom of the world foolish? 21 For since, in the wisdom of God, the world did not get to know God+ through its wisdom,+ God was pleased through the foolishness+ of what is preached to save those believing. 1 Corinthians 1:19 -21
