Dave Armstrong has posted a series of "25 Short Arguments on the Difficulties of Perspicuity (Clearness of Scripture for Salvation)" (link) from his book "501 Biblical Arguments Against Sola Scriptura: Is the Bible the Only Infallible Authority?" I can see that his list of arguments has received nearly a thousand views, so perhaps it makes sense to provide a response to each of these. The arguments themselves are not long - individually they are no more than smudges that aim to obscure Scripture's clarity. This is number 5/25 of my wiping away of the smudges.
5. Since Protestants can't agree in their interpretation of Scripture, of what practical use is an infallible Bible? If the interpretation is fallible and contradictory, then -- practically speaking -- the Bible in effect is no more infallible than its differing interpretations.
The practical use of the Bible is explained below:
2 Timothy 3:16-17
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: that the man of God may be perfect, throughly furnished unto all good works.
The argument, if we can call this question an argument, seems to be trying to suggest that the appropriate test of the sufficiency of a rule of faith is if everyone agrees about it. But there is no rule of faith about which everyone agrees. To take the alternative for which Armstrong is trying to argue by tearing down Scripture, Roman Catholicism provides a rule of faith in the form her allegedly infallible teachings. Nevertheless, there are differences of opinion among Roman Catholics regarding how to interpret their rule of faith. Thus, if we accept the extremely skeptical premise of this argument, the result is agnosticism: we wouldn't be able to have any rule of faith at all, because people have differences of opinion over any given rule of faith.
