On the Making of Man by Gregory of Nyssa — Read

Yet it may be thou thinkest, having regard to the elements of the universe, that it is a hard thing when the air in us has been resolved into its kindred element, and the warmth, and moisture, and the earthy nature have likewise been mingled with their own kind, that from the common source there should return to the individual what belongs to itself.

Dost thou not then judge by human examples that even this does not surpass the limits of the Divine power? Thou hast seen surely somewhere among the habitations of men a common herd of some kind of animals collected from every quarter: yet when it is again divided among its owners, acquaintance with their homes and the marks put upon the cattle serve to restore to each his own. If thou conceivest of thyself also something like to this, thou wilt not be far from the right way: for as the soul is disposed to cling to and long for the body that has been wedded to it, there also attaches to it in secret a certain close relationship and power of recognition, in virtue of their commixture, as though some marks had been imprinted by nature, by the aid of which the community remains unconfused, separated by the distinctive signs. Now as the soul attracts again to itself that which is its own and properly belongs to it, what labour, I pray you, that is involved for the Divine power, could be a hindrance to concourse of kindred things when they are urged to their own place by the unspeakable attraction of nature, whatever it may be? For that some signs of our compound nature remain in the soul even after dissolution is shown by the dialogue in Hades, where the bodies had been conveyed to the tomb, but some bodily token still remained in the souls by which both Lazarus was recognized and the rich man was not unknown.
