Concerning the definition of inerrancy, Ryrie explains:
Definitions of inerrancy are not plentiful! Errantists equate inerrancy with infallibility and then limit its scope to matters of faith and practice or to revelational matters or to the message of salvation. An example of this: “The Bible is infallible, as I define that term, but not inerrant. That is, there are historical and scientific errors in the Bible, but I have found none on matters of faith and practice” At least this is an honest distinction between infallibility and inerrancy.
In view of this, when defining inerrancy, it is always important to state clearly what it means and what it does not mean.
It does not demand rigidity of style and verbatim quotations from the Old Testament.
