Can humanity decide for itself what is good and evil? What does history tell us?
Without a Supreme Authority defining absolute good and evil, everything is a matter of opinion.
Only the Creator of good can define good. Only a creation that accepts its Creator’s definition of good can achieve true good.
“Woe to those who call evil good and good evil, who put darkness for light and light for darkness, who put bitter for sweet and sweet for bitter.” Isaiah 5:20, Torah
