It doesn’t, does it?? It says “all Scripture”. Period.
And since

the Deuteros **are **Scripture…

My friend, you have just put your finger on the most important point of all. Indeed, that is the very thing which decided for me, long ago, that it was folly (& worse!) to reject the Deuterocanon…Their rejection leads inexorably to the

rejection of Jesus Christ.
Now, I really don’t think that that was what Martin Luther had in mind. But--
it is the logical outcome of depending on those who reject Him, instead of leaning on those who follow after Him.
Something our friend kaycee seems not to care to ponder…
