" This was true in two areas. First of all there was nothing autonomous in the area of final authority. For the Reformation, final and sufficient knowledge rested in the Bible—that is, Scripture Alone, in contrast to Scripture plus anything else parallel to the Scriptures, whether it be the church or a natural theology. Second, there was no idea of man being autonomous in the area of salvation. In the Roman Catholic position there was a divided work of salvation—Christ died for our salvation, but man had to merit the merit of Christ. Thus there was a humanistic element involved. The Reformers said that there is nothing man can do; no autonomous or humanistic, religious or moral effort of man can help. One is saved only on the basis of the finished work of Christ as he died in space and time in history, and the only way to be saved is to raise the empty hands of faith and, by God’s grace, to accept God’s free gift—Faith Alone.
