Traditionally, Revelation was seen as an unfolding prophecy of the things which will take place between the first and second comings of Jesus Christ (Introduction, pg. 1).
See, for example, Dr. Francis Nigel Lee’s list of Apostolic and Church Fathers who interpreted biblical predictions historically, as found in Biblical Predictions Not Preterist but Historicist, Table of Contents, and examined in detail throughout the book.
“The Continuous Historical theory regards the book as giving a continuous history of the church from the first century to the end of the age. Among the leaders of this method of interpretation are Luther, Bengel, Isaac Newton, Elliott, Alford, Barnes, Grattan, Guiness. From the thirteenth century until recently this theory has had almost universal sway.”
