I will bite Winman. Just who is the guilty party, the one responsible for the sin nature? Name that one so he can be punished!
My object was to show Skan's OP premise correct. If men are sinners by necessity, then at best they can be considered victims.
However, if man retains the true ability to choose either good or evil, then a man is 100% responsible for his own sin, and cannot blame another.
So, the Reformed/Calvinist view presents a man as a victim, the non-Cal view presents man as a transgressor.
Skan is correct.
Seeing I believe men truly make their own choices and have no one to blame but themselves, I am under no obligation to provide a cause outside the man's own volition.
It is you that believes a man is a sinner by necessity at birth and must explain what caused this.
