For Christ is our Salvation. For He is our Salvation Who was wounded for us, and fastened with nails to the Wood, and taken down from the Wood, and laid in the sepulchre. But He rose from the sepulchre; and though His wounds were healed the scars remained. For this He judged expedient for His Disciples: that He should keep His scars to heal the wounds of their soul. Augustine, Peace Be To You / The Mystical Body, I. The Heresy of the Manicheans
