Thou shalt not take the name of the LORD thy God in vain; for the LORD will not hold him guiltless that taketh his name in vain. Exodus 20:7
On to number 3, god still seems majorly concerned with his how people view him. Considering he is now 3 for 3 he seems to have a major preoccupation with himself.
The main thing to note here is that this commandment referred to a use of god’s proper name, of course which proper name is a debate in and of itself. One that can, and has, filled entire books on ancient Jewish religion. God was referred to by many names in the Christian Old Testament, especially the earlier parts which has caused some scholars to speculate on whether early Judaism might have been polytheistic. I don’t personally have an opinion on this as I am not well versed enough in the history, nor do I really care, polytheism is no more rational then monotheism in my book.
Most modern Christians spin this to speak about using swear words, specifically things like “god damn it” or “god is a fucking asshole.” Christians always hate it when I say that last one for some reason…
Well, for one, its a threat. God doesn’t really say what his is going to do, but considering some of the other stuff he does in the bible it probably won’t be good.
Now we reach the first commandment to actually make it into American law in some form. I speak, of course, of blasphemy laws. Of course the federal government never had such laws as they would have violated the first amendment. However state governments often have had such laws. Though as far as I know no one has been successfully prosecuted for them since the 14th amendment extended the effects of the bill of rights to all levels of government.
I would say that the 1st amendment puts our law, in a philosophical sense, in a rather strong opposition to this commandment. The government, unlike god, choose to not criminalize what people say in and of itself.
