And this is undeniably certain from experience. For so much as our bodies grow, so much new matter is added to them, over and beside the repairing of what is continually spent; and after a man come to his full growth, so much of his food as every day turns into nourishment, so much of his yesterday's body is usually wasted, and carried off by insensible perspiration--that is, breathed out at the pores of his body; which, according to the static experiment of Sanctorius, a learned physician, who, for several years together, weighed himself exactly every day, is (as I remember) according to the proportion of five to eight of all that a man eats and drinks. Now, according to this proportion, every man must change his body several times in a year. It is true indeed the more solid parts of the body, as the bones, do not change so often as the fluid and fleshy; but that they also do change is certain, because they grow, and whatever grows is nourished and spends, because otherwise it would not need to be repaired. 2. The body which a man hath at any time of his life is as much his own body as that which he hath at his death; so that if the very matter of his body which a man had at any time of his life be raised, it is as much his own and the same body as that which he had at his death, and commonly much more perfect; because they who die of lingering sickness or old age are usually mere skeletons when they die; so that there is no reason to suppose that the very matter of which our bodies consists at the time of our death shall be that which shall be raised, that being commonly the worst and most imperfect body of all the rest. These two things being premised, the answer to this objection can not be difficult. For as to the more solid and firm parts of the body, as the skull and bones, it is not, I think, pretended that the cannibals eat them; and if they did, so much of the matter even of these solid parts wastes away in a few years, as being collected together would supply them many times over. And as for the fleshy and fluid parts, these are so very often changed and renewed that we can allow the cannibals to eat them all up, and to turn them all into nourishment, and yet no man need contend for want of a body of his own at the resurrection--viz., any of those bodies which he had ten or twenty years before; which are every whit as good and as much his own as that which was eaten.
