“Renunciation is nothing else than a manifestation of the cross and of a dying. Therefore you should know that on this day you have died to the world and to its deeds and desires and that, according to the Apostle, you have been crucified to this world and this world to you.
Consider, then, what the cross implies, within whose mystery it behooves you henceforth to proceed in this world, since you no longer live, but he lives in you who was crucified for you.” (John Cassian, The Institutes: Ancient Christian Writers, pg. 96)
