20.
For He was Himself the perfect Seal, and the Church is the key: "He who openeth, and no man shutteth; and shutteth, and no man openeth," 1 as John says. And again, the same says: "And I saw, on the right hand of Him that sat on the throne, a book written within and without, sealed with seven seals; and I saw an angel proclaiming with a loud voice, Who is worthy to open the book, and to loose the seals thereof?" and so forth. "And I beheld in the midst of the throne, and of the four beasts, a Lamb standing slain, having seven horns, and seven eyes, which are the seven Spirits of God sent forth into all the earth. And He came and took the book out of the right hand of Him that sat upon the throne. And when He had taken the book, the four beasts and four-and-twenty elders fell down before the Lamb, having harps and golden vials full of incense, which is the prayers of the saints. And they sing a new song, saying, 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." 2 He took the book, therefore, and loosed it, in order that the things spoken concerning Him of old in secret, might now be proclaimed with boldness upon the house-tops. 3
