“Even the practice of the reformers illuminates the deficiency of sola scriptura.  Luther’s early position proclaimed that everyone, including “the humble miller’s maid, nay, a child of nine,” could interpret the Bible.  However, as Christianity began to fracture, he radically altered his position.  He called the Bible the “heresy book.”  In 1525 he wrote: “There are as many sects and beliefs as there are heads.  This fellow will have nothing to do with baptism; another denies the sacraments; a third believes that there is another world between this and the Last Day.  Some teach that Christ is not God; some say this, some say that.  There is no rustic so rude but that, if he dreams or fancies anything, it must be the whisper of the Holy Spirit and he himself is a prophet.”104”
