The KJV, like all Protestant Bibles, is missing several Old Testament books.
As a believer in Luther’s dogma of “the Bible ALONE,” you lack an infallible authority to determine the cannon of Scripture. As R.C. Sproul once said, the Protestant Bible is “a fallible collection of infallible books.”
Then how do you know, infallibly, whether the Protestant cannon is correct? It’s logically impossible, given your presuppositions, and Luther’s dogma collapses.
Your proof-texts for Luther’s doctrine of the Bible ALONE prove nothing. You are pre-supposing the validity of his teaching.
Defendining “the Bible ALONE” and defending Christianity are NOT the same thing.
I care not whether your Bible has more OT books than mine. It’s not a contest. Those books may/may not be credible. I’m not losing any sleep over it. You talk of Luther and RC Sproul, let them work out their own salvation. I didn’t quote them. You are hung up on infallibility and that is what your church wants. For you to need them. I need Christ and Him alone. There is still time if you are willing. God calls “ Come out of her, my people, that ye be not partakers of her sins, and that ye receive not her plagues”. Read your Bible and not your church literature and walk away from the rituals, statuary, St. Christopher charms, prayer beads, rosaries and amulets. Meet God, one on one and see Him differently.
