Does this not mean that humanity's moral compass comes from Satan, and not God? Or at the very least, was it not Satan who instilled this moral compass in us, where God would have seen us live without one?
I'm Christian (catholic), but I don't know perfectly my own religion (that being possible is another very interesting debate). I really don't know what credit one should give to the Torah (aka the 5 oldest, hebrew books of the Bible, including the Genesis where you find the Adam and Eve thing). Taking them in a litteral way creates a toooon of problems. For example there isn't
one God in the Torah ; Yahvé is only
one of
them.
From a catholic point of view, the power of creating something is exclusive to God. Satan can't create something. This means that he might have lead us to know what's good and bad (which, again, isn't all that clear), but that the possibility of this distinction was created by God.
I will be refering to Saint Augustine all the way here (mostly
De Libero arbitrio). What I know for a fact is that "Moral", as you rightfully call it (as it is a very Christian concept (Nietzsche)), is the fact that your will can decide wether or not it gets along with God's will. The closer your will is to God's will, the more saint you are. For that to make sense, God
created the "free will", the capacity for every man to determine oneself.
God didn't create "moral", as it is just a way of seing things, and not a
thing on its own. He created something in us that allows moral to make sense. Otherwise the Judgement and God's justice wouldn't make any sense. A Divine Restribution (haha) can exist only if men are responsible for what they do.
Conclusion : According to Augustine, God is the one and only origin (not creator) of moral.
Problem : What about Satan ? Did God create the evil ? Why ?
Satan, in the Bible, is litterally "the accuser". He invites God to tempt men to test their will. His only will is to separate men from God ("stn" in hebrew = separation). He is the origin of
some cases of sin. He really doesn't help answering your question imo. In the Bible, he definetly has less importance than people tend to think (ofc he's important, but he's not the cause of all sins, he's not the only demon).
Going back to Augustine for the second question. God created the possibility of choosing. He created good and evil with the free will. The possibility for you to join him on yourself (which is beautiful tbh) necessarily includes the possibility of not joining him ie of sin.
Hope that was clear. Sorry for my bad English. Ask any question.
