Chapter 51.—From the Apocalypse. The Revelation of John likewise tells us that in a new song these praises are offered to Christ: “Thou art worthy to take the book, and to open the seals thereof: for Thou wast slain, and hast redeemed us to God by Thy blood out of every kindred, and tongue, and people, and nation.” 384 384     Rev. v. 9 .
