Being apocalyptic literature, Revelation contains symbols and numbers. It is crucial to understand that these must have been intelligible for the church of the first century (John clearly says in 1:4 and 1:11 that he is writing to first-century churches in Asia Minor). Hence, the key to a correct interpretation of any of the various images in Revelation is to first understand the meaning of the image in its literary context and early church audience and then move on to understand the implications of the church today.
