Read what I said about objective morality again. I never said Christians were perfect. Sin is vindicated by history and our societies today, why is the United States inferior to the past in most ways, because sin and hedonism was allowed.
You said that we imperfectly discover it. What is the difference between that claim and "morality is subjective". If people never "discover" the objective morality you claim exists, then from their perspective morality must be subjective. And since we are humans, our perspective is what matters. Claiming that objective morality exists separately from humanity is a completely unfounded belief.
The US bit is irrelevant as the US is a social construct and it being inferior now is your opinion, which is once again unfounded as you haven't lived in the past. People have always murdered as it is in their nature. Why should sin be prohibited, doesn't that beat the purpose of salvation? If you don't get to choose your own actions you can't claim to be more moral, you were simply frightened into submission. What you are arguing is that forced restrictions make society more comfortable for some individuals (specifically yourself, and a lot of people would disagree). Which is fine, I won't argue that and it has nothing to do with our discussion.
Teaching people to not believe in God allows them to live meaningless lives where they can think only of their physical bodies and work hard in order to imitate people richer than them.
How could they have lived meaningless lives if you believe a universal meaning for human life to exist? Wouldn't you then have to belive that they were unconsciously living out that meaning?
"True existential atheism, burning with hatred to a seemingly unjust god, is a spiritual state, it is an attempt to grapple with the true God, whose ways are so inexplainable, even to the most believing of men and it has been more than once known to end in a blinding vision of him whom the atheist truly seeks, it is Christ who works in your soul." -Nihilism, Seraphim Rose
I don't believe god to be unjust. Once again to me god is just an idea and a symbol I use to represent the concept of "being". But let's exchange god with nature. I don't believe nature to be unjust as justice is once again an idea with no physical grounding. Things simply happen. Cause and affect. Thinking about meaning is for the ones who don't live in the moment. And if there was a meaning, the ones thinking about it are less likely to be living it out.
I believe "sin" to be simply be a functional state one finds themselves in. When someone attacks you it is rage that allows you to fight back. The attraction you feel towards your wife is physically no different to the attraction you feel towards other women, which you would dub lustful. The separation between the two is manmade, in reality it is that same feeling that encourages humans to reproduce, regardless of if it's a sin or not. Once again, functional.
Ego death and adhering to an objective morality is inhumane and self-destructive. Humans aren't robots, they can't be programmed to follow written law. Their values are flexible depending on their environment. They are hypocrites and it is not a bad thing. There is a reason a christian, an atheist, a left winger and a right winger all experience the same fight or flight reaction when a pistol is pointed at their heads. If required to respond with force, they will do it, regardless of belief. Ideology gets overwritten by instinct in extreme situations. One can't help but believe that said instinct is true human nature.
Alasdair MacIntyre was a devout secular Marxist who, after researching for his book, After virtue became a Christian because he observed the lack of morality in society.
One guy I've nevet heard of converting to christianity out of literally functionality has nothing to do with me.
