The Seven Seals of God from the Bible's Book of Revelation are the seven symbolic seals (σφραγῖδα, sphragida) that secure the book or scroll that John of Patmos saw in an apocalyptic vision. The opening of the seals of the document occurs in Rev Ch 5–8 and marks the Second Coming of the Christ and the beginning of The Apocalypse/Revelation. Upon the Lamb of God/Lion of Judah opening a seal on the cover of the book/scroll, a judgment is released or an apocalyptic event occurs. The opening of the first four Seals releases the Four Horsemen, each with his own specific mission. The opening of the fifth Seal releases the cries of martyrs for the "Word/Wrath of God". The sixth Seal prompts plagues, storms and other cataclysmic events. The seventh Seal cues seven angelic trumpeters who in turn cue the seven bowl judgments and more cataclysmic events. Certain words and phrases used in The Revelation had a clearer meaning to ancient readers familiar with objects of their time. For example, important documents were sent written on a papyrus scroll sealed with several wax seals. Wax seals were typically placed across the opening of a scroll, so that only the proper person, in the presence of witnesses, could open the document. This type of "seal" is frequently used in a figurative sense, in the book of Revelation, and only the Lamb is worthy to break off these seals. From the Reformation to the middle of the 19th century, the seals in Revelation have been interpreted through various methods, such as the historicist view that most Protestants adopted and the views of preterism and futurism that post-Reformation Catholic circles promoted. Idealism was also a fairly major view that became realized since the time of Augustine, Bishop of Hippo (AD 345–430). The preterist usually views that John was given an accurate vision of a course of events that would occur over the next several centuries to fulfill the prophetic seals.
