For He alone and singly is the Lamb without spot, without sin; not because His spots are wiped off, but because He never had a spot. He alone is the Lamb of God, for by His blood alone can men be redeemed. (c. 6). This is the Lamb whom the wolves fear; even the slain Lamb, by whom the lion was slain.
