Послание 7 Григория Нисского

And grave-digging itself is divided into forgivable and unforgivable. For if someone, sparing the honor of the dead and not touching the body hidden in the tomb, so that the ugliness of nature does not appear before the sun, uses some of the stones placed on the tomb for some kind of construction, then this, although not commendable, however, as usual, has become excusable when this substance is turned into something better and more generally useful. And to torture the ashes of a body that has been buried in the ground, and to disturb the bones in the hope of acquiring some ornament buried with the deceased, is subject to the same judgment as simple fornication, observing the distinction shown in the previous word, that is: let the primate consider the healing of the healed from his very life in such a way that he can shorten the continuation of penances determined by the rules.
