46 Why should more be said? By the death of One the world was redeemed. For Christ, had He willed, need not have died, but He neither thought that death should be shunned as though there were any cowardice in it, nor could He have saved us better than by dying. And so His death is the life of all. We are signed with the sign of His death, we show forth His death when we pray; when we offer the Sacrifice we declare His death, for His death is victory, His death is our mystery, His death is the yearly recurring solemnity of the world. What now should we say concerning His death, since we prove by this Divine Example that death alone found immortality, and that death itself redeemed itself. Death, then, is not to be mourned over, for it is the cause of salvation for all; death is not to be shunned, for the Son of God did not think it unworthy of Him, and did not shun it. The order of nature is not to be loosed, for what is common to all cannot admit of exception in individuals.
