No I am not. I do not believe we establish our own moral code. I believe God establishes it in each of us as He sees fit.
God’s moral code is the same for all humanity for all time.
It’s not situational ethics,one thing for pone person at one time and something different somewhere or sometime else.
He set forth His moral code in Scripture. You have no choice about what it is. You can only choose to obey it or not and pay the consequences.
If you’re looking for justification of yourself based on some kind of moral relavitism, you aren’t going to find it from God.
