In the first, second, and third chapters of this Book are contained
instructions and admonitions which St. John was commanded to write to
the seven bishops of the churches in Asia. And in the following
chapters, to the end, are contained prophecies of things that are to
come to pass in the Church of Christ, particularly towards the end of
the world, in the time of Antichrist. It was written in Greek, in the
island of Patmos, where St. John was in banishment by order of the
cruel emperor Domitian, about sixty-four years after our Lord's
Ascension.
