From Our Reformed Doctrinal Standards
Belgic Confession of Faith
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, Rom. 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.
