Which argument for God is the most accessible? To really sustain the cosmic beginning argument and the cosmic fine-tuning argument, you have to learn some scientific evidence. Same for the resurrection of Jesus – you have to learn some history. But what about the moral argument? All you need to make that argument is for your opponent to think that something is morally wrong.

First, let’s review the moral argument, from William Lane Craig.

He writes:

We are going to turn now to a discussion of the moral argument for the existence of God. So far we have been looking at philosophical and scientific arguments. This is an ethical argument. There are a wide variety of moral reasons for believing in God, but this is a particularly simple moral argument that I have used over and over again with university students and I find very effective. It really grabs people where they live. This is not just a matter of scientific evidence or philosophical issues that may not impact your life. This is an issue that is vitally important because everyday as you live you make moral choices. So everyday by your behavior you answer the question whether or not you believe that God exists. The argument consists basically of three simple steps:

1. If God does not exist, objective moral values do not exist.

2. Objective moral values do exist.

3. Therefore, God exist.

That is a very simple argument for the existence of God and is easy to memorize. It is just three steps. It is logically valid. If those two premises are true then the conclusion follows necessarily and logically. The only question is: are the two premises true?

But there are some objections to the moral argument. CrossExamined.org has posted a list of five objections to the moral argument from philosopher Paul Rezkalla.

Here are the 5 points:

1. “But I’m a moral person and I don’t believe in God. Are you saying that atheists can’t be moral?”
2. “But what if you needed to lie in order to save someone’s life? It seems that morality is not absolute as you say it is.”
3. ‘Where’s your evidence for objective morality? I won’t believe in anything unless I have evidence for it.’
4. ‘If morality is objective, then why do some cultures practice female genital mutilation, cannibalism, infanticide, and other atrocities which we, in the West, deem unacceptable?’
5.  ‘But God carried out many atrocities in the Old Testament. He ordered the genocide of the Canaanites.’

That last one seems to be popular, so let’s double-check the details:

For starters, this isn’t really an objection to the moral argument. It does not attack either premise of the argument. It is irrelevant, but let’s entertain this objection for a second. By making a judgement on God’s actions and deeming them immoral, the objector is appealing to a standard of morality that holds true outside of him/herself and transcends barriers of culture, context, time period, and social norms. By doing this, he/she affirms the existence of objective morality! But if the skeptic wants to affirm objective morality after throwing God out the window, then there needs to be an alternate explanation for its basis. If not God, then what is it? The burden is now on the skeptic to provide a naturalistic explanation for the objective moral framework.

If you have heard any of these objections before when discussing the moral argument, click through and take a look.

And if you have a non-Christian in your life who likes to make moral statements, it’s a good conversation to have. Where does your standard come from? Is it from your own desires? Is it from cultural conventions, that vary by time and place? Is it from Darwinian evolution? Find out what the answer is, and then respond to it.
