while an error-free book won't alone prove it as divine, errancy from any kind should get the book under suspicion ..
both the bible and The Quran claims inerrancy:
Holy Quran 41:42 No falsehood can approach it(the Quran) from before or behind it: It is sent down by One Full of Wisdom, Worthy of all Praise.
in the clearest of terms the bible also claims to be the verbal ,plenary inspired word of God
2 Timothy 3:16 All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness.
not only inerrancy is specifically affirmed in the bible and the Quran but an inference as well:
the belief of a divine, error-free book is the one that is held by the church for seventeen centuries.
Due to the produced indisputable evidence of inaccuracies in the bible, a tiny minority of modern Christian scholars , began to be more realistic denying the concept that the bible is an error-free book…. Such concept, though realistic, has a tremendous obstacle to gain popularity among Christians ,as it Ignores the serious consequences for declaring that the bible is errant,the consequences would be the answer to the question:
Does Biblical Errancy matter?
quotes by some of the scholars of mainstream Christianity :
“the very nature of inspiration renders the bible infallible, inspiration involved infallibility from start to finish, if inspiration allows for possibility of errors ;then inspiration ceases to be inspiration.
Harold Lindsell, The Battle for the Bible
“Even if the errors are supposedly in ‘minor’ matters, any error opens the Bible to suspicion on other points which may not be so ‘minor.’ If inerrancy falls, other doctrines will fall too.” If we can’t trust Scripture in things like geography, chronology, and history, then how can we be sure we can trust it in its message of salvation and sanctification?
Charles C. Ryrie, Basic Theology, Victor Books, Wheaton, IL, 1987, electronic media.
Again. a belief in limited inerrancy demands the impossible__that a fallible exegete become an infallible discerner and interpreter of (the word of God)within the scripture .This opens the door for confusion and uncertainty ,undergirded by either subjectivism or personal bias.
Indeed can the holy spirit inspire error; can the spirit of truth inspire untruth.?
Handbook of Biblical Evidences By John Ankerberg, John Weldon
“By this word ( inerrancy) we mean that the Scriptures possess the quality of freedom from error. They are exempt from the liability to mistake, incapable of error. In all their teachings they are in perfect accord with the truth.
E. J. Young, Thy Word Is Truth, Eerdmans, Grand Rapids, 1957, p. 113
‘Being wholly and verbally God-given, Scripture is without error or fault in all its teaching, no less in what it states about God’s acts in creation, about the events of world history, and about its own literary origins under God, than in its witness to God’s saving grace in individual lives’ (James Montgomery Boice, Does Inerrancy Matter?, Oakland: International Council on Biblical Inerrancy, 1979, p. 13.)
If the biblical record can be proved fallible in areas of fact that can be verified, then it is hardly to be trusted in areas where it cannot be tested. As a witness for God, the Bible would be discredited as untrustworthy. What solid truth it may contain would be left as a matter of mere conjecture, subject to the intuition or canons of likelihood of each individual. An attitude of sentimental attachment to traditional religion may incline one person to accept nearly all the substantive teachings of Scripture as probably true. But someone else with equal justification may pick and chose whatever teachings in the Bible happen to appeal to him and lay equal claim to legitimacy. One opinion is as good as another. All things are possible, but nothing is certain if indeed the Bible contains mistakes or errors of any kind (Gleason Archer ,Encyclopedia of Bible Difficulties pp. 23-24).
Some say that the Bible is inspired in the same sense that great literature is inspired, as the plays of Shakespeare or the poems of Tennyson and Browning. Such people sometimes say, "I know the Bible is inspired because it inspires me." Really they mean that the Bible is not the infallible Word of God but that it is a good inspiring book even though it has mistakes. Some say that God gave the general thought and left it to men to write it down so that of necessity there would be some slight errors. Some say that the New Testament is authoritative and true, but the Old Testament is imperfect and is simply a survival of primitive religious thinking. Some so-called scholars, who are not scholars enough to know what the Bible claims for itself nor the evidence that it is true, teach a so-called "progressive revelation" and say that none of the Bible is reliable except the very words of Jesus, and they doubt many of the statements of the gospels. Many good men are deceived by these theorists and quote them. Some people say that the Bible contains the Word of God but that not all of it is the Word of God. If one must find for himself or depend upon some modernistic scholar to say just how much of the Bible is really the Word of God and authoritative, of course no two living men, on that plan, would perfectly agree as to what was true and what was not. Some good men very foolishly say that the Bible is inspired and reliable for religious knowledge but is not necessarily true in scientific matters, or in history (John R. Rice, Verbal Inspiration of the Bible, Sword of the Lord Publishers, p. 1).
"The Bible is the inerrant... Word of God. It is absolutely infallible, without error in all matters pertaining to faith and practice, as well as in areas such as geography, science, history, etc." (Jerry Falwell,Finding Inner Peace and Strength,Doubleday, 1982, p. 26, ).
It(The Bible) does not err in its revelation, its assertions relative to doctrine, ethics, history, et al. The autographs were absolutely and totally free from error. The Bible gives a faultless record of everything with which it deals (including lies and faults, at times); it chronicles the record of those errors but does not sanction them. It does claim infallibility in all that it does teach, however. Further, when accurately transmitted/translated, the translation is also inspired, the Word of God" (Biblical Inerrancy: The First Annual Gulf Coast Lectures, Church of Christ, Portland, Texas, 1993, pp. 33-34).
I believe that God moved the men who wrote the Holy Bible so that the very words they wrote and the very thoughts they expressed were given to them by God and miraculously preserved from every possibility of error. I further believe that Holy Scriptures "since they are the Word of God, contain no errors or contradictions, but are in all their parts and words infallible truth, also in those parts that treat of historical, geographical, and other secular matters" . I will go even further since Jesus went further. I believe that the Bible is not only verbally inspired, but is also totally accurate in its tense, mood, voice, and case (in the original autographs) because Jesus says so
William Bischoff, a pastor in Bridgeton, Missouri.
"... But how do you know Jesus except as he is presented to you in the Bible? If the Bible is not God's Word and does not present a picture of Jesus Christ that can be trusted, how do you know it is the true Christ you are following? You may be worshipping a Christ of your own imagination." (Does Errancy Matter by James Boice, page 24)
Once conceding there are errors in the Bible, you have opened a Pandora's Box. How do you know which parts are true if you admit some parts are false. As ICBI said: "... But this position (claiming truthfulness for those parts of the Bible where God, as opposed to men has spoken-ed). is unsound. People who think like this speak of Biblical authority, but at best they have partial Biblical authority since the parts containing errors obviously cannot be authoritative. What is worse, they cannot even tell us precisely what parts are from God and are therefore truthful and what parts are not from God and are in error. Usually they say that the "salvation parts" are from God, but they do not tell us how to separate these from the non-salvation parts." (Does Errancy Matter by James Boice, page 8)
