To Clementina, Patrician.
The Book of Pastoral Rule and Selected Epistles · Saint Gregory the Great (the Dialogist)
Having received your Glory’s letter speaking of the passing away of the late Eutherius of magnificent memory, we give you to understand that our mind no less than yours is disturbed by such a sorrow, in that we see how men of approved repute are by degrees removed from this world, whose ruin is already evidenced in the actual effects of the causes thereof. But it becomes us to withdraw ourselves from it by the wise precaution of conversion, lest it involve us too in its own ruin. And indeed our sorrow for the loss of friends ought to be the more tolerable as our condition of mortality requires from us that we should lose them. Nevertheless, for the loss of aid to our carnal life He Who granted permission for its removal is powerful to console, and to come Himself as a comforter into the vacant place.
GregReg 3.10.4
