I believe you when you say that you are good!
As you are not new on these forums then you know that Catholics believe in the natural laws. So, the fact that an atheist even cares about right or wrong is proof that there is a God.
Yesterday, my well fed cocker spaniel dug under our coop and killed 13 young hens. She didn’t eat the chickens. She just went on a bloody, killing spree.

Is my dog bad? Not really. She is following generations of instinct that has been bred into her being. I can’t really call her actions, from her point of view, moral or immoral.
There is really no reason that the actions of humans should be considered moral or immoral unless something is imprinted on our minds that make us view our actions in the light of morality.
Deb, You make an old argument. You say that because atheists believe there is such a thing as right and wrong, that means that there must be objective moral laws. You say that, by definition, all laws require a law-giver, and that law-giver must be God.
I structure my rebuttal as follows:
Reply #1 Just because human beings have developed a moral compass doesn’t mean that it must have been designed by a higher intelligence. It could have (and probably did) evolve naturally. (Elaboration below)
Reply #2 Even if your argument is valid (and it’s not), it just points to a higher intelligence, and not specifically the Christian God. (Elaboration below)
Reply #3 I address your implicit argument that if God doesn’t exist, there’s no reason to be moral.
Here goes:
Reply #1 Before I begin, let me set up my defense with a few definitions. There’s a difference between
proscriptive laws, such as the ones given by governments, and
descriptive laws, such as the ones enumerated by scientists. Descriptive laws merely observe the world around us and then come up with language to express certain patterns, whereas proscriptive laws are rules given by human beings that direct human societies or behavior. For example, laws regarding interstate commerce are proscriptive laws. The law of gravity is a descriptive law. Certainly, proscriptive laws require a lawgiver by definition, and in our example of interstate commerce it might be the state or national government. However, descriptive laws - though enumerated by certain specific scientists who discovered the particular pattern in nature - do not have a law giver. There is no “department of gravity” that checks up on the objects floating around in the universe, making sure that everyone is obeying the law. On the contrary, we simply use the word “law” to describe patterns in nature. It is short sighted to jump to the conclusion that “every law has a law-giver.” The Christian apologist merely uses wordplay to swap out our definition of “descriptive law” for “proscriptive law” at a time that is convenient for him or her. It’s not a reasonable argument.
So, can we categorize the principles of right and wrong into proscriptive or descriptive law? Well, we certainly have civil laws that govern human behavior. Murder, for example, carries a penalty of many years in prison - or even death - if convicted in court. We certainly give civil laws based on morality. But on the other hand, we obviously don’t feel hatred towards murderers
because of the written law. We would feel that
regardless of if we were living in a society with laws against murder or not. I think it would be accurate to say that almost every human being feels anger towards the act of murder, and most would only ever consider taking the life of another human being only in the most extreme of circumstances, such as war or in self-defense.
Christians have said that this must mean there is an invisible law on our heart. Well, it seems to me that most human beings do indeed feel great emotions when confronted with certain moral offenses. This is such a sweeping phenomenon in human societies that calling it a “law” might be accurate. Furthermore, it is obviously a very good law to have! A society characterized by murder would quickly destroy itself. But, just be clear, the idea that all-human-beings-have-a-moral-compass would only be a *descriptive *law, such as the law of gravity. We are merely describing something in the Universe in terms of a “law.” Once again, it’s fallacious to swap out the *descriptive *definition of law for a
proscriptive definition of a law.
So, as I stated above, I agree that there is something imprinted on our minds that makes us feel outrage when murder occurs. It’s clear, obvious, and scientifically verifiable. Indeed, there are scientists who are actively working to figure out how exactly human beings developed this human ‘moral compass’, but just because we may not know exactly how human beings developed it doesn’t mean that God *must *have created it. That’s no more sophisticated an argument than the 2nd century Greeks believing that because there is no rational explanation for lightning, it must origin with the gods.
There is certainly an active scientific community looking at this question,
and they have many rational,
non-theistic explanations.
