So, with your logic Romans 13:4 is false teaching and there should be no penalty for any crime because Jesus bore the full penalty for every sin. Sure. Ok. /s
Lose the attitude and I’ll continue with you.
You think Romans 13:4 contradicts 1 John 2:2 and 2/3rds of the New Testament written by the same hand and inspired by the same Holy Spirit?
Romans 13:4 is talking about about man’s legitimate police authority which God backs up and is necessary in a fallen world to keep peace and order. It is NOT talking about negating the “one sacrifice for all” by Christ on the cross for all sin ever committed.
Incarceration of a dangerous criminal for the safety and welfare of the community is one thing. And if the police must use deadly force in the heat of the incident for the their and/or others’ safety, so be it. Kind of like war.
But deliberate execution of a prisoner in confinement is unjust double jeopardy.
