I think that you are correct in your thinking. Many people believe that using the title God automatically means their God you are cursing. Since I'm a trainee God I know what I'm talking about.<quoted text>
According to the third commandment? "Thou shall not take the name of the Lord thy God in vain?"
I always felt that meant not to profess that you align yourself with God as your lord, but then act like a complete @SS.
Seems like taking it to mean "Thou shalt not cuss" is a cheap and easy cheat - as I've come to expect from the contingent across the aisle.
Jesus hey suse, Yahweh, Jehovah are not real names of the Jewish or Christian God or G-D. So if I hit my finger with a hammer and said "dam Jesus christ" that is not talking God's name in vain. That would be only cussing.
I understand it would be disrespectful in the presence of religious ones who think your talking about their God in a disrespectful way as would a lot of plain old cussing .
"Let no corrupt speech proceed out of your mouth, but such as is good for edifying as the need may be, that it may give grace to them that hear".
As a trainee God "not really" I see nothing other than cussing in itself would qualify as taking God's name in vain. Meaning not living up to the commands required by the bible.
So I agree with your understanding on this also.
