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 may we compare any writings of men, though ever so holy, 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, 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.
