You keep saying that your OP was an on-point rebuttal of my 16 points. I'll humor you momentarily on this allegation. You said:
There are only no conceivable exception [to the maxim] if you do not believe the scriptures. Where point one falls down and can be dismissed right away is that there is only one standard for GOOD and EVIL; SIN and RIGHTEOUSNESS and that is the Word of God given through God's 10 commandments *ROMANS 3:20; ROMANS 7:7; 1 JOHN 3:4; PSALMS 119:172.
Where in that statement is even one hypothetical scenario that runs contrary to the maxim? The maxim was proposed as an obvious counterexample to Sola Scriptura. All you've done is respond, "Sola Scriptura is true, not your maxim." But you've done nothing to discredit the maxim!
You insinuate that the ten commandments tell us everything we need to know about righteousness. You mean like this command:
"Thou shall not kill."
And yet Moses and Joshua purposed to slaughter 7 nations to lay hold of Canaan. And Heb 3 and 4 says they were right to do it. God's law is unchanging only in the sense that the spirit of the law - its underlying meaning - is love. But the specifics of how to fulfill it vary from situation to situation, individual to individual, and nation to nation - and it can even involve one nation slaughtering another (viz. going to battle against Hitler).
You claim that the ten commandments are God's written Word. Actually they began as God's spoken Word. They were authoritative because the Voice is authoritative in whatever it spoke TO ISRAEL. Again, God can speak a very different set of commands to me today because I'm not Israel. The written Word can't tell me the specifics of God's will FOR ME - it can only assure me that God's will is always love and righteousness, in the final analysis.
Yes the 10 commandments began as God's voice. And your claim is that a voice must, in all cases, be tested by Scripture? But at that point Israel had no Scripture to test the voice. I guess they should have ignored it, then?
Still waiting for you to find me one hypothetical scenario that clearly calls for taking exception to the maxim.
