One of the "four horseman of New Atheism" Daniel Dennet once remarked that the best way to establish a point is state the opposition's case as effectively as possible, almost having them remark, "Wow! I wish I said it that well!" and proceeding to tear it apart piece by piece.

In this spirit, let us recount the famed "Problem of Evil."
"One may suppose that God exists, an attribute to him the qualities of Omnibenevelence (all-goodness, James 1:17) and Supreme Justice. Subsequently observing the world as is, this seems incredibly unlikely. Everyday people are killed for qualities they are neither responsible for nor endorsing. Genocide, rape, deadly, painful disease, and more, unimaginable atrocities exist, all in the presence of this "loving god." Consider evils completely unrelated to human will: natural disasters, disease, and, perhaps most impeccably, the judgement of peoples for not believing in Christ as their savior (for they often live in situations and places that never hear, nor could they possibly be expected to believe something as crazy as a man's resurrection). Is it just OR loving to allow such evils to exist. Imagine, if you will, a world, just slightly better. A world with, say, a cure for cancer. Or perhaps a world where cancer doesn't exist. The ease at which these "better" world are conceptualized implies, at a minimum, that the world is anything but "the best possible world." These ideas, and more, beg the conclusion that no such God is possible to exist."
NOW the tearing. This is an excellent time to reiterate the importance of presuppositions. Many great Christian thinkers have noted that criticisms such as the Problem of Evil and ones like it beg the question of morality's existence. You see, if there is no "morality" without God, how can one criticize God for being "immoral" or "unjust" if those very terms are meaningless without His defining and causing them to be?
The question, it seems then, is can morality exist without the existence of a just God?
The answer is, unequivocally, "there cannot exist and objective moral system without the existence of a just God." Objectivity is the principle that an idea is unchanging based on the subject's interpretation; i.e. there exists things that are right and wrong. If morality is subjective, then no act can be considered "right" or "wrong." There would be no truth value to these claims, for each "subject" would interpret what is "right" by what is best for them given their situation. You may be thinking, "this seems plausible, a morally relative world... Think about it, why can I judge another culture's practice just because of my experience?" Interestingly enough, that rhetorical question is self-defeating. For if one supposes morality is relative, what reason is their to prefer the benefit-of-the-doubt type thinking this relativist exhibits, as opposed to, say, me, who thinks it is perfectly alright for me to judge Lord's Resistance Army (think: Joseph Kony) as performing moral atrocities. In a relative world, neither view is better, for "better" and other qualitative terms are meaningless. In fact, carrying a morally relative world to its logical conclusion forces one to concede that there exists any merit for stopping or desiring to stop the Holocaust, the Crusades, the Inquisition, the Rwandan Genocide, rape, child molestation, punching you in the face, etc. If one has more power than another, and wills something so, then they ought to do it, for it is only as wrong as (and if) they perceive it to be so.
Again, I can guess what you're thinking. That's a terribly obtuse mode of thinking. Not only are we judging those attempting to be sympathetic in their understanding of others' opinions, but we're further implying that those particular people are implicitly supporting the destruction of a people for no reason in particular. We express, as sincerely as possible, that this is not the case. We know that these conclusions are egregious. It is obvious you do not support the Nazis or the Ku Klux Klan, and yet both of these groups believed that what they were doing would make the world better and even save it from destruction. In the world with no objective morality, there can be no judgement of these actions. Consider with me for a moment the logical conclusions of such a world, a place where nothing is "right" or "wrong" but simply happens. In such a world, the Nazis are no different from the Red Cross, and the KKK and AARP are equally moral. In this world, there is no law, no morality, no hope of justice. In short, it is an absurd world in which stable existence is impossible.
Our claim is that there cannot exist objective morality without God. You may ask why can't a natural explanation give rise to an objective moral system? In this regard, we have many examples of ethos, but we'll go straight to the top. Richard Dawkins, perhaps the world's most prominent atheistic writer, claims, "life has no design, no purpose, no evil and no good, nothing but blind pitiless indifference." Dawkins has, God bless him (and have mercy on him), taken Naturalism (the worldview in which all that exists is the universe and nothing else) to its logical conclusion. Apart from intelligent and seemingly rational people subscribing to this atheistic view, it is not that hard to show how morality cannot be objective without God. Objective, by definition, means "relative to a standard." Humans, although relatively consistent in their morals (see Romans 2:13-15 for the reason) are all different, and therefore cannot function as such a standard of ourselves. The standard cannot be the "societal optimum" as many suppose. In such a system, morals are formed from social systems in order to organize peoples and improve livelihood. This still doesn't warrant morals as "objective." First, certain acts would be moral in certain time periods and immoral in others (like, for example, rape in societies that struggle to procreate). Moral theories like Kantism (Immanuel Kant), Utilitarianism (John Stuart Mill and Jeremy Bentham), and Virtue Ehtics (Aristotle) are all either inconsistent for a number of different criticisms or, by definition, subjective. (we can explain why if there are questions)
Thus, we arrive at moral theories for God. The best of these is Divine Command Theory. Divine Command Theory, correctly formulated, consistently explains an objective morality in the world. DCT explains God as "essentially good" meaning that in his perfection, it would be logically impossible to do something evil. His nature subsequently becomes the standard by which we judge the moral goodness of actions. In His creation of us, God made is such that "[we] show that the work of the law is written on their hearts, while [our] conscience also bears witness, and [our] conflicting thoughts accuse or even excuse [us]." (Romans 2). Thus we literally do make moral judgements based on innate principles, judging off the standard of God's goodness. This explains why essentially no person thinks rape or child molestations is "right" or even acceptable behavior.
For the sake of rigor, DCT's biggest criticism is the Euthyphro Dilemma. Originally posited in Plato's Euthyphro, it questions the notion of God-defined principles. Is an action "good" because it is moral by God's standard, or does the action align with God's standard because it is "good." If the first is true, God could, hypothetically, ordain the slaughter of kittens as moral. If the latter is true, God is unnecessary for moral action. The flaw in this criticism is the first formulation. The hypothetical is a ridiculous counterfactual, essentially formulated "if God is essentially good in all He does, could he ordain something as bad?" Obviously, no. Analyzing the axiom of DCT and saying it inconsistent by an illustration of Euthyphro's dilemma is purposefully contradicting the axiom, rather than actually realizing a contradiction.

1. Morality is objective.
2. Natural theories of morality do not give rise to objective moral systems.
3. DCT is a consistent, theistic moral theory allowing for and implying an objective moral system. By this conclusion, we substantiate the claim that you must first presuppose God's actual existence in reality to even consider the moral value of the attributes that follow in this world.
Hopefully, that makes sense to everyone. If you have any questions, comments, or ideas for future posts; comment or email us at theology.guys@gmail.com! Our next post will look at the problem from where we currently stand. God and objective morality exist, but how can God and his objective morality be consistent with the world we inhabit?
God Bless!
