Article 7: The Sufficiency of the Holy Scriptures to be the Only Rule of Faith.
We believe that those Holy Scriptures fully contain the will of God, and that whatsoever man ought to believe unto salvation is sufficiently taught therein. For, since the whole manner of worship which God requires of us is written in them at large, it is unlawful for any one, though an apostle, to teach otherwise than we are now taught in the Holy Scriptures; nay, though it were an angel from heaven, as the apostle Paul saith. For, since it is forbidden to add unto or take away any thing from the Word of God, it doth thereby evidently appear that the doctrine thereof is most perfect and complete in all respects.
Neither do we consider of equal value any writing of men, however holy these men may have been, with those divine Scriptures, nor ought we to consider custom, or the great multitude, or antiquity, or succession of times and persons, or councils, decrees, or statutes, as of equal value with the truth of God, for the truth is above all; for all men are of themselves liars and more vain than vanity itself. Therefore we reject with all our hearts whatsoever doth not agree with this infallible rule, which the apostles have taught us, saying, Try the spirits whether they are of God. Likewise, if there come any unto you, and bring not this doctrine, receive him not into your house.
 
Westminster Confession 1:6:
The whole counsel of God concerning all things necessary for His own glory, man’s salvation, faith and life, is either expressly set down in Scripture, or by good and necessary consequence may be deduced from Scripture: unto which nothing at any time is to be added, whether by new revelations of the Spirit, or traditions of men. Nevertheless, we acknowledge the inward illumination of the Spirit of God to be necessary for the saving understanding of such things as are revealed in the Word: and that there are some circumstances concerning the worship of God, and government of the Church, common to human actions and societies, which are to be ordered by the light of nature, and Christian prudence, according to the general rules of the Word, which are always to be observed.
II Timothy 3:15-17:
And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus. All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works.
I Corinthians 14:26c, 40:
Let all things be done unto edifying.
Let all things be done decently and in order.
