Notice there is no mention of “inerrancy” or “without
error”. The key word is “useful”, a far softer and more humble word than
“inerrant” or even “infallible”.
The other key word used by Paul is “God-breathed”, sometimes
translated “inspired”. This word is important because it gives scripture an
authority and uniqueness beyond ordinary writings and books. Still, there is
nothing in the word “God-breathed” or “inspired” that implies complete freedom
from error.
