"Tell me, is God good because he decides what the good is, or is He good because He is being measured to a standard other than Himself? If the first is the case, then Morality is simply an arbitration and has no objective stake in the truth. If the latter is the case, then God is no longer the basis for objective moral truth and we no longer require Him to fill such a role.
This is called the Euthyphro Dilemma, based on Plato's character of the same name, and is often given in response to the Moral Argument for the existence of God. Have fun with it."
This dilemma Euthyphro faced is used today as an attack against Christianity. An example of such attacks is that of Bertrand Russell in his argument against faith, Why I am Not a Christian.
"If you are quite sure there is a difference between right and wrong, you are then in this situation: Is that difference due to God's fiat or is it not? If it is due to God's fiat, then for God Himself there is no difference between right and wrong, and it is no longer a significant statement to say that God is good. If you are going to say, as theologians do, that God is good, you must then say that right and wrong have some meaning which is independent of God's fiat, because God's fiats are good and not good independently of the mere fact that he made them. If you are going to say that, you will then have to say that it is not only through God that right and wrong came into being, but that they are in their essence logically anterior to God."
Russell is endeavoring to undermine God, as portrayed in the Bible, by cornering believers and giving them only two options, both extremely inimical to Christian theism. The question is much like the well known, "Can God create a rock he cannot move?" These questions are enough to make you pull out your hair in despair! Which of course, is exactly their purpose. What better way to turn someone away from their faith than to give them the feeling of inferiority due to confusion and lack of answers to preposterous questions.
To choose the first option takes away God's holiness and righteousness. Though God told us that adultery and covetousness are wrong, He could have arbitrarily said otherwise. There would be no way to know if what we did was right or wrong because the concepts would be relative. God could chose at any time to change the moral standards He set up. We know that this is wrong, because the Bible makes it quite clear that God CANNOT sin. If He cannon sin, that leads us to the conclusion that He did not arbitrarily decide what was right, and what was wrong.
What then? We are left now with the second option. This too, like the first, is not in keeping with what we know from scripture. To state that God is held by a higher law is blasphemous. In the case of this being true, He loses His sovereignty and becomes no better than us. Dependent, secondary, and subject.
Christianity has now 'lost'. With only these two options, there is nowhere to turn. The God that we know and have put our faith in has seemingly been proven false. God is either not good, or He is not sovereign. Both claims refute the Bible. If the Bible is found to be untrue by any contradiction or fallacy of any kind, what is left of Christianity? It is no more. Totally and utterly made obsolete.
I am going to give the solution to this dilemma in a separate post. This is basically just to lay out the problem, let all of you think about it, and hopefully comment on it. Then in a few days (at most a week, all depending on busyness with school), I will post the follow up.
