Jamieson, Fausset and Brown on 2 Corinthians 3:14-18

14-18. Parenthetical: Of Christians in general. He resumes the subject of the ministry, 2Co 4:1.

minds--Greek, "mental perceptions"; "understandings."

blinded--rather, "hardened." The opposite to "looking steadfastly at the end" of the law (2Co 3:13). The veil on Moses' face is further typical of the veil that is on their hearts.

untaken away ... which veil--rather, "the same veil ... remaineth untaken away [literally, not unveiled], so that they do not see THAT it (not the veil as English Version, but 'THE Old Testament,' or covenant of legal ordinances) is done away (2Co 3:7, 11, 13) in Christ" or, as Bengel, "Because it is done away in Christ," that is, it is not done away save in Christ: the veil therefore remains untaken away from them, because they will not come to Christ, who does away, with the law as a mere letter. If they once saw that the law is done away in Him, the veil would be no longer on their hearts in reading it publicly in their synagogues (so "reading" means, Ac 15:21). I prefer the former.
