" Those who would argue for the infallibility or the inerrancy of scripture logically should also claim the same infallibility for the churches in the fourth and fifth centuries, whose decisions and historical circumstances left us with our present canon. This is apparently what would be required if we were to only acknowledge the twenty-seven NT books that were set forth by the church in that context. Was the church in the Nicene and post-Nicene eras infallible in its decisions or not?
