"The authority of the Holy Scripture, for which it ought to be believed, depends not upon the testimony of any man or church, but wholly upon God (who is truth itself), the author thereof; therefore it is to be received because it is the Word of God."

The church doesn't make Scripture God's word. It recognizes that it is God's word. It is what it is. 2+2=4 even if the whole world says otherwise.
