Christian Fundamentalists, Jehovahs Witnesses, and some other Christian groups, hold that the Judeo-Christian Bible is the complete, 100% error-free (inerrant) word of Yahweh/Jehovah God. This doctrine is sometimes referred to as the "inerrancy doctrine," and its adherents are sometimes referred to as "inerrantists." "Inerrantists" are not necessarily "apologists." "Errancy," then, is the viewpoint that the Bible is not error-free. Thus, an "errantist" might believe that the Bible contains errors in history, science, geography, taxonomy, prophecy, and so forth, and s/he may well set out to prove the existence of such errors in the Bible to others. "Apologists," in turn, may set out to discredit any claims made by "errantists" by explaining why an apparent error is not an actual error. And on and on it goes.
