Okay Post..,I think I have irrefutable proof for you, that the Ten Commandments are...shall we say, "Grandfathered", into the New Covenant.
Eternal life was not promised to those under the Law of Moses..correct?
So....Eternal Life was only offered under the New Covenant.
When a man asked Jesus, What he must do to have Eternal life?...The answer Jesus gave him, was by accord of the New Covenant.
His answer...."Keep the Commandments". The Man then asked, "Which ones?" Jesus said unto Him, “‘Thou shalt do no murder; thou shalt not commit adultery; thou shalt not steal; thou shalt not bear false witness; honor thy father and thy mother (Matthew 19:18&19)
Jesus gave this man five of the Ten Commandments...to keep.
If he told this man the truth, the Ten Commandments are still in play. If he lied to this man, the Ten Commandments are obviously not part of the New Covenant....for it would show that Jesus sinned.
Now...you must decide, Did Jesus tell him the Truth, or did Jesus bear false witness?
Yes..or No?
