12 Unto whom it was revealed This passage has been strangely perverted by fanatics, so as to exclude the fathers who lived under the law from the hope of eternal salvation. For it does not deny that the prophets usefully ministered to their own age, and edified the church, but teaches us that their ministry is more useful to us, because we are fallen on the ends of the world. We see how highly they extolled the kingdom of Christ, how assiduous they were in adorning it, how diligently they stimulated all to seek it; but they were by death deprived of the privilege of seeing it as it now is. What else then was this, but that they spread the table, that others might afterwards feed on the provisions laid on it. They indeed tasted by faith of those things which the Lord has by their hands transmitted to be enjoyed by us; and they also partook of Christ as the real food of their souls. But what is spoken of now is the exhibition of this blessing, and we know that the prophetic office was confined as it were within limits, in order that they might support themselves and others with the hope of Christ, who was to come. They therefore possessed him as one hidden, and as it were absent — absent, I say, not in power or grace, but because he was not yet manifested in the flesh. Therefore his kingdom also was as yet hid as it were under coverings. At length descending on earth, he in a manner opened heaven to us, so that we might have a near view of those spiritual riches, which before were under types exhibited at a distance. This fruition then of Christ as manifested, forms the difference between us and the prophets. Hence we learn how they ministered to us rather than to themselves.
But though the prophets were admonished from above that the grace which they proclaimed would be deferred to another age, yet they were not slothful in proclaiming it, so far were they from being broken down with weariness. But if their patience was so great, surely we shall be twice and thrice ungrateful, if the fruition of the grace denied to them will not sustain us under all the evils which are to be endured.
Which are now reported to you, or announced to you. He again marks the difference between the ancient doctrine and the preaching of the gospel. For as the righteousness of God is revealed in the gospel, having a testimony from the law and the prophets, so also the glory of Christ, of which the Spirit testified formerly, is now openly proclaimed. And at the same time he hence proves the certainty of the gospel, because it contains nothing but what had been long ago testified by the Spirit of God. He further reminds them, that under the banner of the same Spirit, by his dictation and guidance, the gospel was preached, lest they might think of anything human in this case.
Which things the angels desire to look into It is indeed the highest praise to the gospel, that it contains treasures of wisdom, as yet concealed and hidden from angels. But some one may object, and say that it is not reasonable that things should be open and known to us which are hidden from angels, who always see the face of God, and are his ministers in ruling the church, and in the administration of all his blessings. To this I answer, that things are open to us as far as we see them in the mirror of the word; but our knowledge is not said to be higher than that of angels; Peter only means that such things are promised to us as angels desire to see fulfilled. Paul says that by the calling of the Gentiles the wonderful wisdom of God was made known to angels. for it was a spectacle to them, when Christ gathered into one body the lost world, alienated for so many ages from the hope of life. Thus daily they see with admiration the magnificent works of God in the government of his church. How much greater will their admiration be, at witnessing the last display of divine justice, when the kingdom of Christ shall be completed! This is as yet hidden, the revelation of which they still expect and justly wish to see.
The passage indeed admits of a twofold meaning; either that the treasure we have in the gospel fills the angels with a desire to see it, as it is a sight especially delightful to them; or that they anxiously desire to see the kingdom of Christ, the living image of which is set forth in the gospel. But the last seems to me to be the most suitable meaning.
