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.⁷

⁷ 2 Pet. 1:19–21; 2 Tim. 3:16; 1 Thess. 2:13; 1 John 5:9

We may be moved and induced by the testimony of the church of God to a high and reverent esteem of the Holy Scriptures; and the heavenliness of the matter, the efficacy of the doctrine, and the majesty of the style, the consent of all the parts, the scope of the whole (which is to give all glory to God), the full discovery it makes of the only way of man's salvation, and many other incomparable excellencies, and entire perfections thereof, are arguments whereby it does abundantly evidence itself to be the Word of God; yet notwithstanding, our full persuasion and assurance of the infallible truth, and divine authority thereof, is from the inward work of the Holy Spirit bearing witness by and with the Word in our hearts.⁸
