To 2003cobra (mainly) and others who disagree with Inerrant Scripture doctrine:
In order to have a productive discussion, we must agree on certain terms and vocabulary. First, naturally, would be "error." If a simple misspelling is classified as "error," then you are correct. However, if a simple misspelling, or slight numerical error is not what renders something as "errant," then the doctrine of innerancy applies. Also, one must consider the historical context of the Scripture composition. The Old Testament was written, transcribed, and copied over a very long period of time, centuries in fact. The Hebrews were very meticulous when it came to preserving the Old Testament books and documents. The contents of the New Testament, however, were all copied very quickly (in the want to be able to send out as many copies as possible for converting non-Christians), thus allowing for spelling errors, possible variations in numerical representations, etc. It was in I believe 390 AD, in which St. Jerome began to compile the Greek, Aramaic, and Hebrew Manuscripts, creating the Septuagint/Vulgate. This text is regarded as being the most scholastic and complete gathering, comparison, and composition of the Scriptures. St. Jerome sought to create as close to original manuscript composition, as possible. It is from this text that various Bibles come from. (If we need to discuss various versions, such as comparatively the Douay-Rheims, King James, New International, English Standard, Wycliffe, etc)
Now, the doctrine of inerrancy, can be found in two locations, with strict definition. We have the Chicago Statement on Biblical Inerrancy, declaring the doctrine that the Protestant Bible "is without error or fault in all its teaching"; or, at least, that "Scripture in the original manuscripts does not affirm anything that is contrary to fact" (source: wikipedia). Now, various Protestant denominations and groups have gone on to declare that Scripture is infallible, and incapable of any error, in much stricter confines.
We also have the Catholic Church's declaration expressed by the Second Vatican Council, citing earlier Catholic declarations, in the following: "Since everything asserted by the inspired authors or sacred writers must be held to be asserted by the Holy Spirit, it follows that the books of Scripture must be acknowledged as teaching solidly, faithfully and without error that truth which God wanted put into sacred writings for the sake of salvation".The Council adds: "Since God speaks in Sacred Scripture through men in human fashion, the interpreter of Sacred Scripture, in order to see clearly what God wanted to communicate to us, should carefully investigate what meaning the sacred writers really intended, and what God wanted to manifest by means of their words." (source: Catechism of the Catholic Church, also supported on wikipedia)
If you note, neither one of the above declares that there are no spelling errors, or absolute infallibility. Yet, logically, it makes sense to work one's way forward through history, in order to find why such declarations were made.
Here is where we get to where we must also agree on a particular theological principle. We must agree that Jesus is God Incarnate. If we disagree on this, then it is pointless to progress on the attributes of Scripture, since we do not agree on one of the (if not, as I would argue, the) central figures in Christianity.
Assuming that we agree, we would then say that Jesus, as God Incarnate, is infallible. Jesus will never, in past, present, or future, declare or teach something that is false. From this, we can jump to when Jesus endows the Apostles with the Holy Spirit (again, infallible). From here, we progress to the Apostles (Matthew and John) composing their respective Gospel accounts. If, guided by the Holy Spirit, while composing their accounts, we can definitively say that their accounts are inerrant, due to the Holy Spirit being inerrant/infallible. Historically, we can also trust the Apostles' disciples, who would want to as accurately as possible, transcribe future Gospel accounts.
So, to trust Jesus, is to trust the Apostles, which leads to trusting the Scriptures to be inerrant.
Here ends my opening statement. The floor is yours.
