It's impossible to teach morality without religion. If you leave God out of the picture, there is no morality. God and His Son Jesus taught humanity what morals are. Without God, man is a selfish, brutal, rude, cruel, greedy creature. If you don't believe me, just look at all the people running around who say they don't believe in God and who won't take what He teaches us in the Bible seriously. The only thing keeping most of them from committing terrible crimes against other people is fear of getting caught by the police and punished by the judicial system (which is founded on Biblical principles). Without government and without religion, man is little more than a brute.
