The Self-Donation of God, pg. 70:
"The book of Revelation centers on Jesus Christ as both the author and object of the Church's liturgical activity. By his death and resurrection Jesus Christ has actualized a new creation and determines his bride the Church as a new creation by freeing her from sin, death, and the Devil. He thereby actualizes her as a creature capable of reflecting his glory through a sacrifice of praise. This occurs when humanity is re-created in the Divine Service through Word and sacrament. Nevertheless, as the book of the seven seals reveals, the divine act of redemption has a corresponding act of judgment. By his opening the book of the testament (the book of the seven seals), God in Christ unleashes divine judgment on the dark forces of the old creation and their addiction to false worship. He also redeems his Church so that the message of judgment becomes glad tidings to the earthly and heavenly Church."
