You appear to be under the understanding that morality is objective; (something that can be demonstrated as right/wrong) rather than subjective (something that is believed to be right/wrong).
If you had asked, I would have explained clearly, that the Christian worldview entails BOTH objective and subjective morality, not either OR, the objective is accounted for in God, and the subjective in His creatures. How simple is that? Bet you cannot account for or justify any objective good or evil within your worldview without borrowing from mine, which you do, like it or not.
I understand morality to be subjective; meaning it doesn’t exist outside the context of human thought and because human thought is constantly changing, the human concept of morality (the only concept that exists) is constantly changing. What people believe about morality is based on the society they were raised in, not fact.
Interesting, I wasn't raised in Hebrew society, and yet that is what my morality is based on, Biblical ethics. As a matter of fact, the Biblical morality I agree with, goes against the morality of the society I was raised in, and laws related to ethics have been changed, which are against ethics taught in Scripture. Further, the Biblical/Christian ethic, has never changed, that Christians fail to consistently and always be true to a Biblical code of ethics, is quite different than the ethics themselves, and Christians will confess their sins and failures and admit fault.
Math is objective, and math equations can be demonstrated as accurate 100% of the time. Cyanide will kill you 100% of the time and it can be demonstrated why it happens.
Unfortunately, within your worldview, even math is subjective, because you see, mathematics are conceptual and immaterial in nature, and like the law of non-contradiction (which every person posting here has assumed without question) assume the necessary preconditions for intelligibility, namely the God of Christianity whom exists outside of self and the necessary supremely intelligent mind having comprehensive knowledge of the entire universe, including ethics, mathematics, laws of logic, etc.
But can you demonstrate rape as evil? I think not; we believe rape to be evil, but we can’t demonstrate 100% of the time that it is evil.
You forgot an important word to my claim, the word "infant", which makes a world of difference. This isn't my first rodeo, I've been down this road many times. If I had worded it differently, you might try arguing that it could potentially be necessary for the survival or continuation of a race, family line, etc. That argument cannot be used with infants.
Can you provide proof that it is sick and disgusting? Or is this your subjective beliefs.
There is no need to provide proof, but it's interesting you should ask.
But my point was that which is believed to be wrong today was believed to be right yesterday; and that which is believed to be wrong yesterday, is seen as right today
So basically morality is a human construct, an illusion, a way of describing behavior, but essentially it is no different than what we evolved from, and ultimately matters about as much as the stardust that everything will eventually return to?
