25 Again and again, my reader, I admonish you to be patient, and to learn what I also have learned through patience; and yet, before I take the veil off the dragon's face, and briefly explain Origen's views respecting the resurrection (for you cannot know the efficacy of the antidote unless you see clearly what the poison is), I beg you to read his statements with caution, and to go over them again and again. Mark well that, though he nine times speaks of the resurrection of the body, he has not once introduced the resurrection of the flesh, and you may fairly suspect that he left it out on purpose.
Well, Origen says in several places, and especially in his fourth book “Of the Resurrection,” and in the “Exposition of the First Psalm,” and in the “Miscellanies,” that there is a double error common in the Church, in which both we and the heretics are implicated: “We, in our simplicity and fondness for the flesh, say that the same bones, and blood, and flesh, in a word, limbs and features, and the whole bodily structure, rise again at the last day: so that, forsooth, we shall walk with our feet, work with our hands, see with our eyes, hear with our ears, and carry about with us a belly never satisfied, and a stomach which digests our food.
Consequently, believing this, we say that we must eat, drink, perform the offices of nature, marry wives, beget children. For what is the use of organs of generation, if there is to be no marriage? For what purpose are teeth, if the food is not to be masticated? What is the good of a belly and of meats, if, according to the Apostle, both it and they are to be destroyed? And the same Apostle again exclaims, 'Flesh and blood shall not inherit the Kingdom of God, nor shall corruption inherit incorruption.'”
This, according to him, is what we in our rustic innocence maintain. But as for the heretics, among whom are Marcion, Apelles, Valentinus, Manes (a synonym for Mania), he says that they utterly deny the resurrection of the flesh and of the body, and allow salvation only to the soul, and hold that it is futile for us to say that we shall rise after the pattern of our Lord, since our Lord also Himself rose again in a phantom body, and not only His resurrection, but His very nativity was docetic or imaginary; that is, more apparent than real.
Origen himself is dissatisfied with both opinions. He says that he shuns both errors, that of the flesh, which our party maintain, and that of the phantoms, maintained by the heretics, because both sides go to the opposite extremes, some wishing to be the same that they have been, others denying altogether the resurrection of the body. “There are four elements,” he says, “known to philosophers and physicians: earth, water, air, and fire, and out of these all things and human bodies are compacted.
We find earth in flesh, air in the breath, water in the moisture of the body, fire in its heat. When, then, the soul, at the command of God, lets go this perishing and feeble body, little by little all things return to their parent substances: flesh is again absorbed into the earth, the breath is mingled with the air, the moisture returns to the depths, the heat escapes to the ether. And as if you throw into the sea a pint of milk and wine, and wish again to separate what is mixed together, although the wine and milk which you threw in is not lost, and yet it is impossible to keep separate what was poured out; so the substance of flesh and blood does not perish, indeed, so far as concerns the original matter, yet they cannot again become the former structure, nor can they be altogether the same that they were.”
Observe that when such things are said, the firmness of the flesh, the fluidity of the blood, the density of the sinews, the interlacing of the veins, and the hardness of the bones is denied.
