Whence do you know this?

From the holy gospel, which God himself first revealed in Paradise; afterwards published by the holy patriarchs and prophets, and foreshadowed by the sacrifices and other ceremonies of the law; and lastly fulfilled by his only begotten Son.

Article 2: By what means God is made known unto us.

We know him by two means: first, by the creation, preservation and government of the universe; which is before our eyes as a most elegant book, wherein all creatures, great and small, are as so many characters leading us to contemplate the invisible things of God, namely, his power and divinity, as the apostle Paul saith, Romans 1:20. All which things are sufficient to convince men, and leave them without excuse. Secondly, he makes himself more clearly and fully known to us by his holy and divine Word, that is to say, as far as is necessary for us to know in this life, to his glory and our salvation.

Article 3: Of the written Word of God.

We confess that this Word of God was not sent, nor delivered by the will of man, but that holy men of God spake as they were moved by the Holy Ghost, as the apostle Peter saith. And that afterwards God, from a special care, which he has for us and our salvation, commanded his servants, the prophets and apostles, to commit his revealed word to writing; and he himself wrote with his own finger, the two tables of the law. Therefore we call such writings holy and divine Scriptures.

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 anything 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.
