Here’s an interesting dilemma for Protestants. We argue against the infallibility of the Pope on the basis that no man can perfectly hear God and infallibly declare doctrine. There’s also some confusion about the difference between infallibility on matters of doctrine and personal sinlessness but we won’t dig too much into that.
Now, at the same time, we affirm the infallibility of a book…a book written by humans that we know were not sinless, that we believe nevertheless were able to produce infallible teaching as they were guided and enabled by the Holy Spirit.
The difference in these two views is only by a matter of degrees. One accepts infallible teaching and doctrine directly from a man who occupies a specific office and believes that the Holy Spirit enables him to speak infallibly on matters of faith and practice. The other simply accepts the same thing from a variety of men in written form. And on top of that, the one that believes in the infallibility of the Pope when speaking ex cathedra on matters of faith and practice affirms that such teaching still must not contradict anything in the Bible.
So my question is, if you can accept by faith that imperfect men could be infallibly guided by the Holy Spirit to produce an infallible Bible, why is the notion that the Holy Spirit could infallibly guide a Pope in the same manner such a non-starter?
