Morality doesnt prove a god. You can get these teachings from any book from even modern authors. Jumping from this to "Know what there has to be a single ominpotent being that made everything but he wont do anything nowadays because reasons." is what has a lot of people so miffed.
If the bible was just presented as a book of the teachings and how you should learn how to behave and not all this other fantastical bullshit about a god that clearly isnt there and doesnt give a shit, I think a lot of "atheists" would be just fine with it. Nobody would be out there trying to prove or disprove anything. But no, we gatta have all this shit.
objective morality does necessarily require God. a book itself isn't the origin of morality, just because another book can repeat the same truth doesn't mean morality itself is justified in a particular book. morality is grounded in the being of God.
your worldview murder = "i don't like murder", it's a preference
the argument is as follows:
A is the necessary precondition for B
B, therefore A
God is the necessary precondition for immaterial transcendental categories
immaterial transcendental categories exists, therefore God exists.
if you disagree, what is your epistemic justification for truth, reason, meaning, purpose, objective morality, induction and universals in your worldview? I don't mean "you can't do a particular moral action unless you personally believe in God". Use is not a justification, I am asking how in your materialistic worldview where there is no God how do you know these things exist and what is your justification for their existence?
