Calvin's view of Scripture

I'm a little behind on commenting, but I couldn't help but be struck by the similarity of Calvin's language concerning Scripture and that of our confession.  Of course, I'm sure the authors of the Westminster (from which the 1689 was derived) leaned heavily on Calvin.  But it's amazing how well the confession digests Calvin's thought here.

I was especially struck by these:

4.  The authority of the Holy Scripture, for which it ought to be believed, dependeth 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.

5. We may be moved and induced by the testimony of the church of God to an 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 doth 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.

There is much here to ponder.  Part of me finds this hard to swallow.  How can the authority of Scripture be Scripture?  How can it authenticate itself?  I wish I had more time to discuss this and to wrestle over it in this forum.  But in short, I found the following comments from Calvin helpful reminders:

Some worthy persons feel disconcerted, because, while the wicked murmur with impunity at the Word of God, they have not a clear proof at hand to silence them, forgetting that the Spirit is called an earnest and seal to confirm the faith of the godly, for this very reason, that, until he enlightens their minds, they are tossed to and fro in a sea of doubts.

Isaiah, moreover, while reminding us that the prophetical doctrine would prove incredible not only to strangers, but also to the Jews, who were desirous to be thought of the household of God, subjoins the reason, when he asks, “To whom has the arm of the Lord been revealed?” (Isaiah 53:1). If at any time, then we are troubled at the small number of those who believe, let us, on the other hand, call to mind, that none comprehend the mysteries of God save those to whom it is given.
