Something I have learned over the years is that some Christians do not know the name of their own god. While I’m not familiar with Jewish and Muslim familiarity with “His” common name, I find this tantamount to a child not knowing the name of its father. He doesn’t have a name, he’s just “Dad.” In this case, He’s just “God.” This is not the case.
The name of the Abrahamic god is Yahweh. Pronunciation is 100% up in the air since the Roman’s did a very good job of making sure that everyone who knew how to pronounce the name became exhumed and if anyone still does know the proper pronunciation, they aren’t talking (Come on Jews! Throw the Biblical scholars a fucking bone! Unless you don’t have one, in which case, carry on). Nonetheless, that’s his name, don’t wear it out.
On a side note, Christians, you are unequipped to take the Lord’s name in vain. You are your god’s proverbial redheaded step children. He didn’t even tell you his name. You CAN’T take it in vain. You can’t even pronounce it correctly. Many of you don’t even know it. Either way, “goddamn” is not a swear in Christianity. “Fuck Yahweh and his tyrannical bullshit” on the other hand would be a swear. That would be taking the Lord’s name in vain. A more applicable blaspheme would be “Damn you by Yahweh.” After the person you used it on figures out what you’re talking about, they’ll be highly offended and you’ll be highly damned. If you believe in that stuff.
And now you know!
