The sixth article addressing the authority of God's Word, we consider how catechisms, confessions, and even creeds, hold authority only to the extent that they properly reflect Scripture. Article 7: The Sufficiency of Scripture 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 the Word of God, or take anything away from it, it is plainly demonstrated 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 times 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 whether they are from God,” and also, “Do not receive into the house or welcome anyone who comes to you and does not bring this teaching.”
