Ever since the beginning of times people have believed that morality can only be understood by religion. It is believed that religion is the basic foundation and the code they accept to set their moral aspects of life. Any nonreligious views only draw the world as a kingdom that is in complete chaos. Since morality is best understood by religion, the clergy, who are the religious authorities, are assumed to be the authorities of morality as well. The clergy consist of people who occupations revolve around religion such as priests and pastors. Even though there are only mere human beings, there are viewed to have the ultimate insight in the proper way of living.
The idea behind an all loving God and the ultimate rule maker of the moral code describes the theory of Divine Command. The Divine Command Theory states that the question of what is morally right is a matter of being commanded by God and morally wrong is a matter of being forbidden by God. This is basically saying when ethics and morality comes into question, following Gods commands is the only way of being right. Inquiring that God is all knowing which consists of possessing wisdom beyond any other, people believe God is never wrong. There is also the notion that God is the creator of all human beings and the world was created in his image therefore all the rules set by our creator seems to be the only rules that make absolute sense.
Many people find it comforting to believe that a loving God is always watching over and caring for them, and when anything good or bad happens to them, this is all part of his plan for their life. Also, religion is obviously very comforting when faced with the death of a loved one. It's much easier and more reassuring to believe that Grandma is free from pain now, up in Heaven with Jesus where she's waiting for us to join her for eternity, than to think that she has simply ceased to exist and the universe will have forgotten her in a couple of generations.
