26 “For another reason,” he says, “we confess the resurrection of our bodies, those which have been laid in the grave and have turned to dust; Paul's body will be that of Paul, Peter's that of Peter, and each will have his own; for it is not right that souls should sin in one body and be tormented in another, nor is it worthy of the Righteous Judge that one body should shed its blood for Christ and another be crowned.” Who, hearing this, would think he denied the resurrection of the flesh?
“And,” he says, “every seed has its own law of being inherent in it by the gift of God, the Creator, which law contains in embryonic form the future growth. The bulky tree, with its trunk, boughs, fruit, leaves, is not seen in the seed, but nevertheless exists in the seed by implication or, according to the Greek expression, by the spermatikos logos. There is within the grain of grain a marrow, or vein, which, when it has been dissolved in the earth, attracts to itself the surrounding materials, and rises again in the shape of stalk, leaves, and ear; and thus, while it is one thing when it dies, it is another thing when it rises from the dead; for in the grain of wheat, roots, stalk, leaves, ears, trunk are as yet unseparated.
In the same manner, in human bodies, according to the law of their being, certain original principles remain which ensure their resurrection, and a sort of marrow, that is a seed-plot of the dead, is fostered in the bosom of the earth. But when the day of judgment shall have come, and at the voice of the archangel, and the sound of the last trumpet, the earth shall totter, immediately the seeds will be instinct with life, and in a moment of time will cause the dead to burst into life; yet the flesh which they will reconstitute will not be the same flesh, nor will it be in the old forms.
To give you the assurance that we speak the truth, let me quote the words of the Apostle: 'But some one says, How shall the dead rise? And with what body will they come? You fool, that which you sow, you sow not that body which shall be, but a bare grain, it may be of wheat, or the seed of a vine and a tree.' And as we have already made the grain of wheat, and to some extent the planting of trees, the subject of our reasoning, let us now take the grape-stone as an example. It is a mere granule, so small that you can scarcely hold it between your two fingers.
Where are the roots? Where the tortuous interlacing of roots, of trunk and off-shoots? Where the shade of the leaves, and the lovely clusters teeming with coming wine? What you have in your fingers is parched and scarcely discernible; nevertheless, in that dry granule, by the power of God and the secret law of propagation, the foaming new wine must have its origin. You will allow all this in the case of a tree; will you not admit such things to be possible in the case of a man?
The plant which perishes is thus decked with beauty; why should we think that man, who abides, will receive back his former meanness? Do you demand that there should be flesh, bones, blood, limbs, so that you must have the barber to cut your hair, that your nose may run, your nails must be trimmed, your lower parts may gender filth or minister to lust? If you introduce these foolish and gross notions, you forget what is told us of the flesh, namely, that in it we cannot please God, and that it is an enemy; you forget, also, what is told us of the resurrection of the dead: 'It is sown in corruption, it shall rise in incorruption.
It is sown in dishonour, it shall rise in glory. It is sown in weakness, it shall rise in power. It is sown a natural body, it shall rise a spiritual body.' Now we see with our eyes, hear with our ears, act with our hands, walk with our feet. But in that spiritual body we shall be all sight, all hearing, all action, all movement. The Lord shall transfigure the body of our humiliation and fashion it according to His own glorious body. In saying transfigure he affirms identity with the members which we now have.
But a different body, spiritual and ethereal, is promised to us, which is neither tangible, nor perceptible to the eye, nor ponderable; and the change it undergoes will be suitable to the difference in its future abode. Otherwise, if there is to be the same flesh and if our bodies are to be the same, there will again be males and females, there will again be marriage; men will have the shaggy eyebrow and the flowing beard; women will have their smooth cheeks and narrow chests, and their bodies must adapt themselves to conception and parturition.
Even tiny infants will rise again; old men will also rise; the former to be nursed, the latter to be supported by the staff. And, simple ones, be not deceived by the resurrection of our Lord, because He showed His side and His hands, stood on the shore, went for a walk with Cleophas, and said that He had flesh and bones. That body, because it was not born of the seed of man and the pleasure of the flesh, has its peculiar prerogatives. He ate and drank after His resurrection, and appeared in clothing, and allowed Himself to be touched, that He might make His doubting Apostles believe in His resurrection.
But still He does not fail to manifest the nature of an aërial and spiritual body. For He enters when the doors are shut, and in the breaking of bread vanishes out of sight. Does it follow then that after our resurrection we shall eat and drink, and perform the offices of nature? If so, what becomes of the promise, 'The mortal must put on immortality.'”
