But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ. But their minds were blinded - By resting in the letter, shutting their eyes against the light that was granted to them, they contracted a hardness or stupidity of heart. And the veil that was on the face of Moses, which prevented the glory of his face from shining out, may be considered as emblematical of the veil of darkness and ignorance that is on their hearts, and which hinders the glory of the Gospel from shining in.
Until this day remaineth the same veil - They are still ignorant of the spiritual meaning and intention of their own law, called here παλαια διαθηκη, the old covenant. See the word explained in the preface to St. Matthew.
In the reading of the Old Testament - Here is an evident allusion to the conduct of the Jews in their synagogues: when they read the law they cover their whole head with a veil, which they term the טלית tallith, veil, from טלל talal, to cover; and this voluntary usage of theirs, the apostle tells us, is an emblem of the darkness of their hearts while they are employed even in sacred duties.
Which veil is done away in Christ - It is only by acknowledging Christ that the darkness is removed, and the end and spiritual meaning of the law discerned.
