John Calvin Commentary 2 Corinthians 3:10

"For verily that which hath been made glorious hath not been made glorious in this respect, by reason of the glory that surpasseth." — 2 Corinthians 3:10 (ASV)

What was rendered glorious. This is not a correction of what came before, but rather a confirmation, for he means that the glory of the law is extinguished when the gospel comes forth. As the moon and stars, though in themselves they are not merely luminous but diffuse their light over the whole earth, do, nevertheless, disappear before the brightness of the sun, so, however glorious the law was in itself, it has, nevertheless, no glory in comparison with the excellence of the gospel. Hence it follows that we cannot sufficiently prize or hold in sufficient esteem the glory of Christ, which shines forth in the gospel like the splendor of the sun when beaming forth, and that the gospel is foolishly handled, indeed, is shamefully profaned, where the power and majesty of the Spirit do not appear, so as to lift people’s minds and hearts heavenward.
