And that which you sow, you sow not that body that shall be, but bare grain, it may by chance be wheat, or of some other grain:
All Commentaries on 1 Corinthians 15:37 Go To 1 Corinthians 15
John Chrysostom
AD 407
For the things before spoken meet the question, how they are raised; but this, the doubt, with what manner of body they come. But what is, you sow not that body which shall be? Not an entire ear of grain, nor new grain. For here his discourse no longer regards the resurrection, but the manner of the resurrection, what is the kind of body which shall rise again; as whether it be of the same kind, or better and more glorious. And he takes both from the same analogy, intimating that it will be much better.
But the heretics, considering none of these things, dart in upon us and say, one body falls and another body rises again. How then is there a resurrection? For the resurrection is of that which was fallen. But where is that wonderful and surprising trophy over death, if one body fall and another rise again? For he will no longer appear to have given back that which he took captive. And how can the alleged analogy suit the things before mentioned? Why, it is not one substance that is sown, and another that is raised, but the same substance improved. Else neither will Christ have resumed the same body when He became the first-fruits of them that rise again: but according to you He threw aside the former body, although it had not sinned, and took another. Whence then is that other? For this body was from the Virgin, but that, whence was it? Do you see to what absurdity the argument has come round? For wherefore shows He the very prints of the nails? Was it not to prove that it is that same body which was crucified, and the same again that rose from the dead? And what means also His type of Jonah? For surely it was not one Jonah that was swallowed up and another that was cast out upon dry land. And why did He also say, Destroy this temple, and in three days I will raise it up? For that which was destroyed, the same clearly He raised again. Wherefore also the Evangelist added, that He spoke of the temple of His body. John 2:19-21
What is that then which he says, You sow not the body that shall be? i.e. not the ear of grain: for it is the same, and not the same; the same, because the substance is the same; but not the same, because this is more excellent, the substance remaining the same but its beauty becoming greater, and the same body rising up new. Since if this were not so, there were no need of a resurrection, I mean if it were not to rise again improved. For why did He at all pull down His house, except He were about to build it more glorious?
This now, you see, he said to them who think that it is utter corruption. Next, that none again might suspect from this place that another body is spoken of, he qualifies the dark saying, and himself interprets what he had spoken, not allowing the hearer to turn his thoughts from hence in any other direction. What need is there then of our reasonings? Hear himself speaking, and explaining the phrase, You sow not the body that shall be. For he straightway adds, but a bare grain, it may chance of wheat, or of some other kind; i.e., it is not the body that shall be; not so clothed, for instance; not having a stalk and beard, but a bare grain, it may chance of wheat, or of some other kind.
