I do not approve of infanticide. And even if I did, in your view it could not be morally repugnant because there is no God to set the standards of morality. Also, I am a great proponent of Mormonism. If there is no penalty or eternal consequence, there is no law. As the Book of Mormon prophet Alma wrote:
The assertion that god is required for morality is completely unsupported. infanticide is wrong not because god says so, but because I myself was once an infant and I wouldn't much have liked to have been killed. If you need a penalty or eternal consequence not to behave like an evil person, then that just means you're an evil person and a wuss.
If there is no God, then there can be no law; so where else can the law come? From men. But men aren't consistent in their laws or moral outlooks. In the Canaanite religions, it was okay to commit infanticide and to combine it with torture and to have orgies as part of the religious order. If there's no God, then the laws of men could be reprehensible to me, but A-Okay with our society. In either way, Cofty, what gives you the right to set the precepts of morality? Or to condemn the infanticide of the Canaanites? I could feed kittens to bulldogs and who could condemn it if I thought it was okay? The only way man instinctively knows right from wrong is through the Light of Christ, which is given to all men. And you condemn the author of that light which you misuse to judge God which is the greatest irony of your argument.
I, for one, am quite grateful that men aren't consistent in their laws and moral outlooks. If they'd stuck with it, then rape would still be a viable way to choose your wife (read your bible, if an isrealite rapes a woman he gets to marry her and she has no say) and we'd be stoning people to death because their father stole a robe. There are certainly many laws that I find reprehensible, but other support. why is that proof that god exists? Everyone has the right to determine their own morality, just so long as it doesn't interfere with the reasonable rights of others.
You make a blind assertion that instinctive morality can only come from god, I make the evidence-based assertion that instinctive morality comes from evolution. Species that didn't have some instinctive desire to help each other out and not kill their own kind likely went extinct pretty quickly. It doesn't take much thought to conclude that morality is an important aspect of human (and many animals') nature and without it we would not have survived as a species. What evidence do you have that god is the origin of morality? Just going to stick with your argument from incredulity?
