I believe that in the coming years the fundamental battle in the church will be over the authority, sufficiency, necessity, and clarity of the Bible. Is the Bible the final, absolute authority or can we look to tradition, ancient cultures, or other types of revelation as equal to or even superior to God’s Word ? Is the Bible sufficient for man’s salvation and to understand how to live a godly life or do we need tradition, science, psychology, or personal revelation from God? Is the Bible necessary to be saved and live a holy life or can men “who, through no fault of their own, do not know the Gospel of Christ or his Church, but who nevertheless seek God with a sincere heart, and, moved by grace, try in their actions to do his will as they know it through the dictates of their conscience – achieve eternal salvation?” Finally, is the Bible clear enough on how man is saved and how he may live a godly life or do Christians need another source to clean up the Bible for them?
Because I see this as a key front in the war on the Christian faith I have been slowly accumulating books and articles on the Scriptures from those who agree with my Protestant, Reformed convictions and from those who do not. I have also been reading the various confessions and catechisms to see what they say about this. In my reading I found this wonderful explanation of the sufficiency of Scripture in Belgic Confession Article 7. All the bold is mine.
We believe that this Holy Scripture contains the will of God completely and that everything one must believe to be saved is sufficiently taught in it. For since the entire manner of service which God requires of us is described in it at great length, no one– even an apostle or an angel from heaven, as Paul says- ought to teach other than what the Holy Scriptures have already taught us. For since it is forbidden to add to or subtract from the Word of God, this plainly demonstrates that the teaching is perfect and complete in all respects. Therefore we must not consider human writings– no matter how holy their authors may have been– equal to the divine writings; nor may we put custom, nor the majority, nor age, nor the passage of time or persons, nor councils, decrees, or official decisions above the truth of God, for truth is above everything else. For all human beings are liars by nature and more vain than vanity itself. Therefore we reject with all our hearts everything that does not agree with this infallible rule, as we are taught to do by the apostles when they say, “Test the spirits to see if they are of God,” and also, “If anyone comes to you and does not bring this teaching, do not receive him into your house.”
