Or The Apocalypse, the book that winds up the accepted canon of Holy Scripture, of the fulfilment of the prophecies of which there are three systems of interpretation: the Praeteritist, which regards them all as fulfilled; the Historical, which regards them as all along fulfilling; and the Futurist, which regards them as still all to be fulfilled. The first is the one which finds favour among modern critics, and which regards it as a forecast of the struggle then impending between the Church under the headship of Christ and the civil power under the emperor of Rome, though this view need not be accepted as excluding the second theory, which regards it as a forecast of the struggle of the Church with the world till the cup of the world's iniquity is full and the day of its doom is come. The book appears to have been written on the occurrence of some fierce persecution at the hands of the civil power, and its object to confirm and strengthen the Church in her faith and patience by a series of visions, culminating in one of the Lamb seated on the throne of the universe as a pledge that all His slain ones would one day share in His glory.
